RP107 Series
Output Capacitor-less 200mA Voltage Regulator (LDO Regulator)

Product Specifications

The RP107 Series are CMOS-based LDO regulators featuring 200 mA output. Since the output capacitor and noise bypass capacitor are able to be reduced and the packages are small WLCSP-4-P5, DFN(PLP)1212-6 and SC-88A, high density mounting on boards are possible. The input voltage (VIN) is as low as Min.1.4 V and the output voltage can be set from 1.0 V. Supply current is as low as 9.5µA compared to existing lines. The CE pin can switch the regulator to standby mode.

FEATURES

Ripple Rejection Typ. 70 dB (f=1kHz, VOUT≤1.2V)
Typ. 65 dB (f=1kHz, 1.2V<VOUT<2.2V)
Typ. 60 dB (f=1kHz, VOUT≥2.2V)
Temperature-Drift Coefficient of Output Voltage Typ. ±100 ppm/°C
Line Regulation Typ. 0.02%/V
Output Voltage Accuracy ±1.0%
Packages WLCSP-4-P5, DFN(PLP)1212-6, SC-88A
Output Voltage Range 1.0V to 4.2V (0.1V steps)
Built-in Fold Back Protection Circuit Typ. 50 mA (Current at short mode)

APPLICATION INFORMATION

CIN: 0.1µF
*) The RP107 Series are using an output capacitor as phase compensation to ensure a stable operation even if the output load fluctuates. To reduce the output voltage fluctuation, it is imperative that a 0.1µF to 10µF output capacitor be used.

  • # … Select (B) without auto-discharge function or (D) with auto-discharge function.

* Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge accumulated in the external capacitor when the chip enable signal is switched from the active mode to the standby mode.
