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.

Absolute Maximum ratings are threshold limit values that must not be exceeded even for an instant under any

conditions. Moreover, such values for any two items must not be reached simultaneously. Operation above

these absolute maximum ratings may cause degradation or permanent damage to the device. These are stress

ratings only and do not necessarily imply functional operation below these limits.
