KCS (TO-220) PACKAGE (TOP VIEW) OUTPUT INPUT COMMON description/ordering information This series of fixed-negative-voltage integrated-circuit voltage regulators is designed to complement the µA78M00 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 essentially make them 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.

The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. ‡ For packages with exposed thermal pads, such as QFN, PowerPAD, or PowerFLEX, θJP is defined as the thermal resistance between the die junction and the bottom of the exposed pad. 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 µ
