Order this document by MC33267/D MC33267 Low Dropout Regulator The MC33267 is a positive fixed 5.0 V regulator that is specifically designed to maintain proper voltage regulation with an extremely low LOW DROPOUT input–to–output voltage differential. This device is capable of supplying output currents in excess of 500 mA and contains internal current limiting and REGULATOR with thermal shutdown protection. Also featured is an on–chip power–up reset 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 SEMICONDUCTOR held low. A programmable time delay is initiated after the regulator has TECHNICAL DATA reached its nominal level and upon timeout, the reset output is re
