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.

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.

ELECTRICAL CHARACTERISTICS

Unless otherwise specified, these specifications in bold type apply over the operating temperature range of

0OC ≤ TJ ≤ +150OC, VIN = 10V, IOUT = 40mA,CIN = 0.33µF, COUT= 0.1µF, and are for DC characteristics only. (Low

duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient

temperature.)
