What is LM340?

What is LM340?

The LM340 and LM7805 Family monolithic 3-terminal positive voltage regulators employ internal current-limiting, thermal shutdown and safe-area compensation, making them essentially indestructible. If adequate heat sinking is provided, they can deliver over 1.5-A output current.

What is a LM7805 voltage regulator?

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.

What is LM7812?

LM7812 is an accurate power transistor with synchronous rectification features as well as a wide frequency response. The maximum output voltage of LM7812 IC is around 12V DC with a minimum input voltage range of 0.25V to 3V.

Which IC is used for series voltage regulator?

LM340 IC
The voltage regulator using the LM340 IC is the mostly used voltage regulator IC.

Where is LM317 used?

The LM317 serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM317 can be used as a precision current regulator.

What is the output voltage of the lm340 and LM7805?

The LM340 and LM7805 devices are a family of fixed output positive voltage regulators with outputs ranging from 3 V to 15 V. They accept up to 35 V of input voltage and with proper heat dissipation can provide over 1.5 A of current.

What kind of voltage regulator is lm340x?

8.2.1 Fixed Output Voltage Regulator The LM340x and LM7805 Family devices are primarily designed to provide fixed output voltage regulation. The simplest implementation of LM340x and LM7805 Family is shown in Figure 18. *Required if the regulator is located far from the power supply filter.
