RP113Q Series

Data Sheet / Flyer

LOW NOISE 150mA LDO REGULATOR

The RP113Q Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit.

These ICs perform with low dropout voltage and a chip enable function. The line transient response and load transient response of the RP113Q Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment.

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

The electrical specifications of the RP113Q Series are completely same as the RP103x Series. Only the difference is the package for the RP113Qxx2. The package of RP113Q Series is small 5-pin SC-88A.

The pin layout of the RP113Qxx2 is different from the RP103Qxx2. Depending on the preference of the package or pinout, various options are available among RP113Q and RP103x Series.
