Semiconductor
LDO Fixed Regulator IC
Description
The A78Rxx Series is a low dropout voltage regulator suitable for various electronic equipments. It provides
constant voltage power source with TO-220F-4L lead full-mold package. Dropout voltage of A78Rxx Series is
below Max.0.5V in full rated current (1.0A). This regulator has various functions such as current limit protection,
over voltage protection and output on/off control.
