150mA Low Supply Current LDO REGULATOR

Data Sheet / Flyer


(2.40MB)

The RP110x Series is a voltage regulator (LDO) IC, which has been developed using the CMOS process technology, with high output voltage accuracy, ultra-low supply current, and low ON-resistance transistor. The IC contains the following components: a voltage reference unit, an error amplifier, a resistor-net for output voltage setting, a current limit circuit for preventing short-circuit, a soft-start circuit, and a chip enable circuit.

By minimizing the supply current to 1μA, the IC is able to prolong the battery life of each system. The external capacitor is 0.1μF with phase compensation. The IC also has a constant slope circuit as a soft-start circuit, which does not require any external capacitor. It minimizes the inrush current and prevents the output voltage overshoot at the start-up.

In addition to the small packaged SOT-23-5 and SC-88A, the RP110x Series offers the ultra-small DFN(PLP)0808-4 package and DFN1010-4, which enables the high density mounting of LDO regulator.
