VOLTAGE REGULATOR
FOR MIDDLE OUTPUT CURRENT
NO. EA-016-0204
Rx5RE SERIES
OUTLINE
The Rx5RE Series are CMOS-based voltage regulator ICs with high output voltage accuracy and ultra-
low quiescent current. 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.
