RP106x Series

Low Voltage 400mA LDO Regulator
The RP106 series are low voltage 400mA voltage regulator. These ICs had been further improved of low-voltage capability compared with previous low-voltage product. Moreover, the output voltage accuracy alsohas achieved ±0.8% (previous products are ±1.0%) and ultra-high accuracy. Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, and a current limit circuits for over-current for the destruction prevention by the over-current. Even the output voltage is set at 1.5V, ON resistance of internal FET is typically 0.55Ω. Since the packages for these ICs are SOT-23-5, SC-88A, DFN(PLP)1212-6 and 0.69mm²(0.4mm ball pitch)WLCSP-4-P5(Wafer Level Chip Size Package), therefore high density mounting of the ICs on boards is possible
