DESCRIPTION

FEATURES

The AMC78L05 is a 3-terminal positive regulator with

a fixed output voltage of 5V. Although it is designed as a

fixed-voltage regulator, the output voltage can be increased

by the use of a simple voltage divider. This regulator can

provide local on card regulation, eliminating the distribution

problems associated with single point regulation. In addition,

it can be used with power-pass elements to make

high-current voltage regulators with 100mA output current.

±5% tolerance of output voltage

Wide input range

Output current > 100mA

Internal thermal overload protection

No External Components

Short circuit protection

Available in 3L plastic TO-92, surface mount

SOT-89 and plastic 8 pin S.O.I.C.

Identical pin assignment to earlier 78L05 series.

Protection features such as thermal shutdown and

current limiting have been designed internally which will

protect the device from damage in case of overload or

overheating.
