RP117K501D-TR Nisshinbo

RP117x Series 100 mA Low Noise, High Ripple Rejection, Negative-voltage LDO Regulator No. EA-379-181207 OVERVIEW The RP117x is a negative voltage LDO regulator that provides high ripple rejection and low output noise. Adding only one capacitor to each input and output pin can make a simple structure and high performance LDO regulator. KEY BENEFITS Provides high ripple rejection rate and low output noise, which is ideal for noise-sensitive devices. Requires only one capacitor for each input and output pin, and is available in small DFN(PLP)1212-6 and SC-88A packages, both of which can utilize the space on board. TYPICAL APPLICATIONS KEY SPECIFICATIONS Input Voltage Range: 10.0 V to 2.5 V CE 0 V to 6 V Output Voltage Range: 5.5 V to 1.0 V Output Current: 100 mA GND Supply Current: Typ. 75 A CE GND Ripple Rejection Rate: Typ. 80 dB, f = 1 kHz V C Output Noise: Typ. 16 Vrms IN C OUT IN 10 V to 2.5 V 2.2 F 1.0 F RP117x (VSET = 5.5 V to 2.0 V) Protection Features: Thermal Shutdown Protection VDD VOUT VOUT Short-circuit Protection Auto-discharge Function PACKAGE SELECTION GUIDE The set output voltage and the package type are user- selectable options.
