What is the difference between 78xx and 79xx?
78xx voltage regulator ICs produce positive fixed DC voltage values, whereas, 79xx voltage regulator ICs produce negative fixed DC voltage values.
Which of the following voltage regulator IC series is complementary to 7800 series?
The 7800 series voltage regulators are ideal for providing the positive rail, and their cousins the 7900 series regulators provide the same but for negative rails. In this way the two voltage regulator chips complement each other as they were intended.
What is IC 78xx?
78xx (sometimes L78xx, LM78xx, MC78xx…) is a family of self-contained fixed linear voltage regulator integrated circuits. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.
What is LM7805 IC?
The LM7805 is a voltage regulator that outputs +5 volts. Like most other regulators in the market, it is a three-pin IC; input pin for accepting incoming DC voltage, ground pin for establishing ground for the regulator, and output pin that supplies the positive 5 volts. Product Features: 3-Terminal Regulators.
What is the advantage of LM317 over the 78XX and 79xx series?
LM317/337 regs are superior to their 78xx/79xx competition in almost every spec. Lower noise, better line rejection, and at least in the case of the LM317, significantly lower output impedance. Walt Jung, in the series on his super-regulator, included tests of the various parameters of popular regulator chips.
What are the three 3 basic types of voltage regulators?
There are three types of Switching voltage regulators: Step up, Step down, and Inverter voltage regulators.

What is 7809 IC?
7809 is a linear voltage regulator IC, 7809 is a 9V Voltage Regulator that restricts the voltage output to 9V and draws 9V regulated power supply. The 7809 is the most common, as its regulated 9-volt supply provides a convenient power source for most TTL components.
What is Lm324n IC used for?
Lm324n is widely used in transducer amplifiers. DC gain blocks and conventional amplifiers circuits are mainly consists of Lm324n. It can be used as a rectifier, oscillator and comparator.
What do the numbers mean on an IC?
All IC chips have a two-part serial number. The first part of the serial number delineates the manufacturer’s information. The second part of the serial number indicates the IC’s technical specifications. Many IC manufacturers produce identical chips with the same technical specifications.
Can I use 7805 without capacitor?
It needs the capacitors because that’s the way the 7805 has been designed. When making an IC, transistors and resistors are very easy to integrate, capacitors of any significant value are much, much harder, so manufacturers can’t use them internally.
What is the difference between 7805 and 7905?
Voltage at the output side of 7805 will be +5V and voltage at the output side of 7905 will be -5V. Common point of both ICs will be shorted and the voltage at this point will be 0V. Voltage across the output of 7805 and common will be 5V. Similarly, voltage across the common and output of 7905 will be 5V.
What is difference between 317 and 337 regulator IC?
LM317 is a positive voltage regulator and LM337 is the negative compliment voltage regulator IC of LM317. The LM317 IC is a 3-terminal voltage regulator that is designed to supply in excess of 1.5 Amps of a DC output voltage range of (1.2-30) Volts.
Are voltage regulators AC or DC?
While voltage regulators are most commonly used for DC/DC power conversion, some can perform AC/AC or AC/DC power conversion as well.
Which voltage regulator is best?

Can you put voltage regulators in series?
There is nothing wrong with cascading regulators in series. It’s done all the time in both commercial and military applications. Just keep in mind that everything connected to the 3.3V regulator will be an additional load on the 6V regulator. Make sure to size the 6V one properly and use adequate bypass caps.
Why LM358 IC is used?
LM358 can be used as transducer amplifier, DC gain block etc. It has large dc voltage gain of 100dB. This IC can be operated on wide range of power supply from 3V to 32V for single power supply or from ±1.5V to ±16V for dual power supply and it also support large output voltage swing.
What is the difference between LM324 and LM324N?
LM324 has the same function as LM324N, The difference between the two is that the LM324 does not specify the package form, and the LM324N package is a plastic dual in-line package. N suffix refers to the packaging: N is DIP.
How do I know my IC grade?
The integrated circuit grade or temperature grade (or rating) is a method of classifying ICs based on their operating temperature – typically based on the intended purpose of a particular chip .
…
Samsung.
| Grade | Operating temperature | |
|---|---|---|
| Min | Max | |
| Industrial | -40°C / -40°F | 85°C / 185°F |
| Military | -55°C / -67°F | 125°C / 257°F |
How do I know my IC value?
Take the terminal-cable from multimeter and connect it one by one to each of the pins of another side separately. If the beep sound occurs of there is a continuity in more than 50% of the combinations then there is a good chance of the IC to be shorted from inside.
Can I use 16v capacitor instead of 5v?
Generally speaking there is no problem using capacitors of a higher voltage rating. They tend to be physically larger and if you go way too high the ESR tends to be higher but in your case it is no problem at all. Too little ESR can be a problem in subcircuits that require some for stability.
Can I use a 50V capacitor instead of an 16v?
Yes, you can use the 50V version. The only difference will be bigger can size and a very slightly improved reliability which you won’t notice.
Does a 7805 need a heatsink?
yes. it requires a heatsink.
What are the 2 types of regulators?
Two types of regulators are used: step regulators, in which switches regulate the current supply, and induction regulators, in which an induction motor supplies a secondary, continually adjusted voltage to even out current variations in the feeder line.
What are the three types of regulators?
Types of Voltage Regulators: Linear vs. Switching
- Linear Regulators. A linear voltage regulator utilizes an active pass device (such as a BJT or MOSFET), which is controlled by a high-gain operational amplifier.
- Switching Regulators.
- LDO Regulators.
- Step-Down and Step-Up Converters.
- Buck-Boost Converters.
