The MC33267 is a positive fixed 5.0 V regulator that is specifically

designed to maintain proper voltage regulation with an extremely low

input–to–output voltage differential. This device is capable of supplying

output currents in excess of 500 mA and contains internal current limiting and

thermal shutdown protection. Also featured is an on–chip power–up reset

circuit that is ideally suited for use in microprocessor based systems.

Whenever the regulator output voltage is below nominal, the reset output is

held low. A programmable time delay is initiated after the regulator has

reached its nominal level and upon timeout, the reset output is released.

Due to the low dropout voltage specifications, the MC33267 is ideally

suited for use in battery powered industrial and consumer equipment where

an extension of useful battery life is desirable. This device is contained in an

economical five lead TO–220 type package.
