RP109x LDO Voltage Regulators

Nisshinbo RP109x LDO Voltage Regulators are CMOS-based voltage regulator ICs featuring high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. The RP109x contains a voltage reference unit, an error amplifier, a resistor net for voltage setting, a current limit circuit, and a chip enable circuit.
