Description

The KA78RH33 is a +3.3V fixed Low Dropout Voltage

Regulator specifically designed for use in low voltage oper-

ation. The maximum load current is 0.8A and the dropout

voltage is guaranteed to be 1V(Typ). The Dropout Voltage

varies with load current. The regulator consists of compos-

ite PNP-NPN pass transistors.
