RP105x SERIES
Low Voltage 400mA LDO Regulator
NO.EA-179-081028

OUTLINE
The RP105 Series are 400mA output type CMOS-based voltage regulator ICs with capability of low input
voltage (Min. 0.9V) and low output voltage (Min. 0.6V). These ICs are remarkably improved the performance at
low input voltage compared with conventional low voltage LDOs, and two power supply voltage type. (Another
power source, Bias pin voltage must be Min. 2.4V). Each of these ICs consists of a voltage reference unit, an
error amplifier, resistor-net for voltage setting, a current limit circuit to avoid the destruction, a UVLO circuit with
monitoring input voltage, and so on.
The RP105 Series have the ultra low on resistance output driver, the on resistance is Typ. 0.4
(@0.8V output,
IOUT=300mA). The built-in driver is Nch MOSFET, thus the load transient response is excellent, (under the
condition of the current between 1mA and 400mA, tr=0.5us, the undershoot level is approximately 50mV).
The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are
DFN(PLP)1212-6, SOT-23-5 and SC-88A therefore high density mounting of the ICs on boards is possible.
