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.

NOTE 1: Maximum power dissipation is a function of TJ(max), θJA, and TA. 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.
