3.0 A 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 pensation. 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 ponents 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.

A mon ground is required between the input and the output voltages. The input voltage must remain typically 2.5 V above the output voltage even during the low point on the input ripple voltage.
- Cin is required if regulator is located an appreciable
