VOLTAGE REGULATOR
FOR MIDDLE OUTPUT CURRENT
R×5RE SERIES
APPLICATION MANUAL
NO.EA-016-0006
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 constant 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
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.
