KIA79M15T

SEMICONDUCTOR TECHNICAL DATA THREE TERMINAL NEGATIVE VOLTAGE REGULATORS -5V, -8V, -12V, -15V. KIA79M05T~KIA79M15T BIPOLAR LINEAR INTEGRATED CIRCUIT A B C D E F 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. G H J K L M O P 1 2 3 N 1. GND 2. INPUT 3.

Although the internal power dissipation is limited, the junction temperature must be kept below the maximum specified temperature in order to meet data sheet specifications. To calculate the maximum junction temperature or heat sink required, the following thermal resistance values should be used ; PACKAGE DPAK Tjmax - Ta JC+ CA JC Typical Applications Bypass capacitors are necessary for stable operation of the KIA79MXX series of regulators over the input voltage and output current ranges. Output bypass capacitors will improve the transient response of the regulator. The bypass capacitors (2.2 F on the input, 1.0 F on the output), Should be ceramic or solid tantalum which have good high frequency characteristics. If aluminum electrolytics are used, their values should be 10 F or larger. The bypass capacitors should be mounted with the shortest leads, and if possible, directly across the regulator terminals.

For output capacitance in excess of 100 F, a high current diode from input to output (1N4001, etc.) will protect the regulator from momentary input shorts.
