LM325
Dual Voltage Regulator
General Description
This dual polarity tracking regulator is designed to provide
balanced positive and negative output voltages at current up
to 100 mA, and is set for ±15V outputs. Input voltages up to
±30V can be used and there is provision for adjustable cur-
rent limiting. The device is available in two package types to
accommodate various power requirements and temperature
ranges.
Features
n ±15V tracking outputs
n Output current to 100 mA
n Output voltage balanced to within 2%
n Line and load regulation of 0.06%
n Internal thermal overload protection
n Standby current drain of 3 mA
n Externally adjustable current limit
n Internal current limit

†Solid tantalum
††Short pins 6 and 7 on dip
†††RCL can be added to the basic regulator between pins 6 and 5, 1 and 2 to reduce current limit.
*Required if regulator is located an appreciable distance from power supply filter.
**Although no capacitor is needed for stability, it does help transient response. (If needed use 1 µF electrolytic.)
***Although no capacitor is needed for stability, it does help transient response. (If needed use 10 µF electrolytic.)
