description
This series of fixed-negative-voltage monolithic
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 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.
The µA79M00C series is characterized for
operation over the virtual junction temperature
range of 0°C to 125°C.

†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. 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 af fect device reliability.
NOTES: 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. 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. The package thermal impedance is calculated in accordance with JESD 51.
