A79M00 SERIES NEGATIVE-VOLTAGE REGULATORS SLVS060E - JUNE 1976 - REVISED APRIL 2000 D D D D D D D KC PACKAGE (TOP VIEW) 3-Terminal Regulators Output Current up to 500 mA No External Components High Power-Dissipation Capability Internal Short-Circuit Current Limiting Output Transistor Safe-Area Compensation Direct Replacements for Fairchild A79M00 Series OUTPUT INPUT COMMON The INPUT terminal is in electrical contact with the mounting base. TO-220AB OUTPUT INPUT COMMON description This series of fixed-negative-voltage monolithic integrated-circuit voltage regulators is designed to complement the A78M00 series in a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. Each of these regulators delivers up to 500 mA of output current. The internal current-limiting and thermal-shutdown features of these regulators make them essentially immune to overload. In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents, and also as the power-pass element in precision regulators. KTP PACKAGE (TOP VIEW) OUTPUT INPUT COMMON The INPUT terminal is in electrical contact with the mounting base. OUTPUT INPUT COMMON The A79M00C series is characterized for operation over the virtual junction temperature range of 0C to 125C.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. Maximum power dissipation is a function of TJ(max), JA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) - TA)/JA. Operating at the absolute maximum TJ of 150C can affect reliability. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal-overload protection may be activated at power levels slightly above or below the rated dissipation. 2.
