VOLTAGE REGULATOR

FOR MIDDLE OUTPUT CURRENT

R×5RE SERIES

OUTLINE

The R×5RE Series are voltage regulator ICs with high output voltage accuracy and ultra-low quiescent

current by CMOS process. Each of these ICs consists of a voltage reference unit, an error amplifier, a driver

transistor, and resistors for setting output voltage, and a current limit circuit. By use of these ICs, a con-

stant voltage power supply circuit with high efficiency can be constructed because the dropout voltage and

quiescent current of these ICs are very small. Furthermore, theses ICs have a built-in current limit circuit.

The output voltage of these ICs is fixed with high accuracy.

Two types of packages, TO-92 and SOT-89 (Mini-power Mold) are available.
