RP105L LDO Voltage Regulator Nisshinbo RP105L Low-Dropout (LDO) Voltage Regulator is a 400mA output type CMOS-based regulator. This voltage regulator features a low input voltage of minimum 0.9V and a low output voltage of a minimum 0.6V. The RP105L consists of a voltage reference unit, an error amplifier, a resistor-net, a current limiter, and a ULVO circuit. The RP105L regulator is available in DFN(PLP)1212-6, DFN1212-5, SOT-23-5, and SC-88A packages. Typical applications are the power source for battery-powered equipment, electrical appliances, and portable communication equipment.
