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.
