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 affect device reliability.
NOTES: 1. Maximum power dissipation is a function of TJ(max),
θ
JA
, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) – TA)/
θ
JA
. 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.
