MOTOROLA ANALOG IC DEVICE DATA
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.
