FEATURES
APPLICATIONS
munication equipment.
The RN5RT Series are voltage regulator ICs with high output voltage accuracy and low supply current developed
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
Even if V
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
