description/ordering information
This series of fixed-voltage integrated-circuit
voltage regulators is designed for a wide range of
applications. These applications include on-card
regulation for elimination of noise and distribution
problems associated with single-point regulation.
In addition, they can be used with power-pass
elements to make high-current voltage regulators.
One of these regulators can deliver up to 100 mA
of output current. The internal limiting and
thermal-shutdown features of these regulators
essentially make them immune to overload. When
used as a replacement for a Zener diode-resistor
combination, an effective improvement in output
impedance can be obtained, together with lower
bias current.
The µA78L00C and µA78L00AC series are
characterized for operation over the virtual
junction temperature range of 0°C to 125°C. The
µA78L05AI is characterized for operation over the
virtual junction temperature range of −40°C to
125°C.
