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-126 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.
