THREE TERMINAL NEGATIVE VOLTAGE REGULATORS

-5V, -8V, -12V, -15V.

KIA79M Series of three-terminal regulators is available

with fixed output voltages of -5V, -8V, -12V, and -15V.

These devices need only one external component-a compensation

capacitor at the output. The KIA79MXX series is packaged in the

TO-220 power package, and is capable of supplying 0.5A of output

current. These regulators employ internal current limiting, safe area

protection, and thermal shutdown for protection against virtually

all overload conditions.

Low ground pin current of the KIA79MXX series allows output

voltage to be easily boosted above the preset value with a resistor

divider. The low quiescent current of these devices with a specified

maximum change with line and load ensures good regulation in the

voltage boosted mode.

FEATURES

Thermal, Short Circuit and Safe Area Protection

High Ripple Rejection.

0.5A Output Current

4% Tolerance on Preset Output Voltage.
