MOTOROLA ANALOG IC DEVICE DATA
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.
Output Current in Excess of 3.0 A
Available with 2% Output Voltage Tolerance
No External Components Required
Internal Thermal Overload Protection
Internal Short Circuit Current Limiting
Output Transistor Safe–Area Compensation
Thermal Regulation and Ripple Rejection Have Specified Limits
Simplified Application
A common ground s required between the nput and the output voltages. The nput
voltage must remain typically 2.5 V above the output voltage even during the ow point
on the input ripple voltage.
*Cin s required f regulator s ocated an appreciable
*
distance from power supply filter. (See Applications
*
Information for details.)
**CO is not needed for stability; however, it does
**
improve transient response.
