Nisshinbo 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.
The Nisshinbo RP109x LDO voltage regulators operate with low dropout voltage and a chip enable function, which prolongs the battery life. The line transient response and load transient response of the devices allow for the power supply of hand-held communication equipment. The device has a 0.1µF ceramic capacitor which contributes to the downsizing of hand-held equipment.
The RP109x is available in SOT-23-5, SC-88A, DFN1010-4, and a 0.8mm square ultra compact DFN(PLP)0808-4 package.
