The LM323,A are monolithic integrated circuits which supply a fixed

positive 5.0 V output with a load driving capability in excess of 3.0 A. These

three–terminal regulators employ internal current limiting, thermal shutdown,

and safe–area compensation. The A–suffix is an improved device with

superior electrical characteristics and a 2% output voltage tolerance. These

regulators are offered with a 0° to +125°C temperature range in a low cost

plastic power package.

Although designed primarily as a fixed voltage regulator, these devices

can be used with external components to obtain adjustable voltages and

currents. These devices can be used with a series pass transistor to supply

up to 15 A at 5.0 V.
