LM323, 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 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.

TECHNICAL DATA

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.

• Output Current in Excess of 3.0 A

• Available with 2% Output Voltage Tolerance

• No External Components Required

A common 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.

*C is required if regulator is located an appreciable

*distance from power supply filter. (See Applications

*Informationfor details.)

**C is not needed for stability; however, it does

**improve transient response.
