LOW DROPOUT
VOLTAGE REGULATOR
1
RN5RT SERIES
OUTLINE
The RN5RT Series are voltage regulator ICs with high output voltage accuracy and low supply current 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 and a current limit circuit.
The output voltage of these ICs is fixed with high accuracy.
The built-in Driver Transistor of low ON Resistance permits developing of low dropout CMOS type regulator as
RN5RT Series.
Even if V
OUT
is shorted to GND, the current limit circuit protects the ICs from destruction.
Furthermore, these ICs have a chip enable function, so that the supply current on standby can be minimized.
Since the package for these ICs is the SOT-23-5 (Mini-mold) package, high density mounting of the ICs on
boards is possible.
