VOLTAGE REGULATOR WITH

EXTERNAL POWER TRANSISTOR

RN5RG SERIES

1

OUTLINE

The RN5RG Series are voltage regulator ICs with an external power transistor with high output voltage accu-

racy and lowest supply current by CMOS process. Each of these voltage regulator ICs consists of a voltage refer-

ence unit, an error amplifier and resistors.

These ICs are suitable for constructing regulators with ultra-low dropout voltage and an output current in the

range of several tens mA to several hundreds mA.

Furthermore, these ICs have a chip enable function, so that the supply current on standby can be minimized.

Since the package for these ICs are SOT-23-5 (Mini-mold) package, high density mounting of the ICs

on boards is possible.

• Ultra-Low Supply Current ..............................TYP. 50µA

• Standby Mode.....................................................TYP. 0.2µA

• Low Temperature-Drift Coefficient of Output Voltage ...................TYP. ±100 ppm/˚C

• Excellent Line Regulation ................................TYP. 0.1%/V

• Output Voltage .................................................Stepwise setting with a step of 0.1V in the range of 2.0V to 6.0V is

possible (refer to Selection Guide).

• High Accuracy Output Voltage ........................±2.5%

• Small Package ..................................................SOT-23-5(Mini-Mold)

FEATURES

APPLICATIONS

• Power source for battery-powered equipment.

• Power source for cameras, VCRs, camcorders, hand-held audio instruments, and hand-held communication

equipment.

• Power source for domestic appliances.
