Positive Voltage Regulators

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.
