description/ordering information

NC − No internal connection

This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of

LP PACKAGE

applications. These applications include on-card

(TO-92, TO-226AA)

regulation for elimination of noise and distribution

(TOP VIEW)

problems associated with single-point regulation. In addition, they can be used with power-pass

INPUT

elements to make high-current voltage regulators.

One of these regulators can deliver up to 100 m A COMMON

of output current. The internal limiting and

OUTPUT

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 PK PACKAGE

impedance can be obtained, together with lower (TOP VIEW)

bias current.

INPUT

The µA78L00C and µA78L00AC series are characterized for operation over the virtual

COMMON

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 OUTPUT 125°C.
