LOW DROP-OUT AND LOW NOISE

VOLTAGE REGULATOR

RN5RZ SERIES

OUTLINE

The RN5RZ Series are voltage regulator ICs with high output voltage accuracy, low supply current, low dropout

voltage and high ripple rejection developed through the use of a CMOS process. Each of these voltage regulator

ICs consists of a voltage reference unit, an error amplifier, output voltage setting resistors, a current limit circuit and

a chip enable circuit. (Provided two types of chip enable circuit ; “H” active and “L” active, that can be selected when

order.)

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

In addition to low supply current from CMOS process, the RN5RZ Series may lengthen battery life through low

dropout voltage and chip enable function thanks to the built-in low ON resistance transistor. Also when compared

with conventional regulators that employ CMOS process, these ICs have superior ripple rejection, input transient

response characteristic and load transient response characteristic thus making these product suitable for power sup-

ply for hand-held communication equipment.

Since the package for these ICs is the SOT-23-5 package, high density mounting of the ICs on boards is possible.
