7812 regulator

Description

The 7812, LM78XX series of three terminal regulators is available with several fixed output voltages making them useful in a wide range of applications. One of these is local on card regulation, eliminating the distribution problems associated with single point regulation. The voltages available allow these regulators to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. Although designed primarily as fixed voltage regulators these devices can be used with external components to obtain adjustable voltages and currents.

LM323 Datasheet PDF – 3A, 5V, Positive Voltage Regulator

Posted on by pinout

What is LM323?

It is part of the LM3xx series of regulators, which are widely used in electronic circuits to regulate and stabilize the DC voltage. This regulator has an internal current-limiting and thermal-shutdown feature that provides protection against overcurrent and overtemperature conditions. It also has a low dropout voltage, which means it can regulate a voltage that is very close to its output voltage.

LM323

Description

The LM323 are three-terminal positive voltage regulators with a preset 5V output and a load driving capability of 3A. New circuit design and processing techniques are used to provide the high output current without sacrificing the regulation characteristics of lower current devices.

The 3A regulator is virtually blowout proof.

Current limiting, power limiting and thermal shut-down provide high level of reliability. An overall worst case specification for the combined effects of input voltage, load current, ambient temperature, and power dissipation ensure that the LM323 will perform satisfactorily as a system element.
