RP122x Series 400 mA Low Noise and Low Supply Current LDO Regulator No.EA-403-210426 OVERVIEW The RP122x is an LDO regulator that provides low output noise, high ripple rejection and fast response characteristics, achieved by low supply current. This device is suitable not only for noise-sensitive applications such as high-performance analog circuits, but also for various applications. KEY BENEFITS Achieves Low Noise, High PSRR and Fast Response. Provides Saving Space by Adopting of 4-pin Small Package without Noise Bypass Capacitor. Provides Long-Duration of Operation for Battery-powered Equipment by Low Supply Current of 9.5 A (Typ.), despite the low-noise LDO. KEY SPECIFICATIONS Input Voltage Range (Max.Rating):1.9 V to 5.5 V (6.0 V) Output Voltage Range: 1.2 V to 4.8 V (0.1 V step) Output Voltage Accuracy: 0.8% (VSET 1.8 V, Ta = 25C) Supply Current: Typ. 9.5 A Output Noise: Typ. 8 Vrms (IOUT = 250 mA) Ripple Rejection: Typ. 90 dB (f = 1kHz) Typ. 85 dB (f = 10kHz) Typ. 65 dB (f = 100kHz) Dropout Voltage: Typ. 0.145 V (IOUT = 400 mA, VSET = 2.8 V, RP122Z) Typ. 0.170 V (IOUT = 400 mA, VSET = 2.8 V, RP122K) Protection Features: Thermal Shutdown Protection (Detection Temp. Typ.165C) Inrush Current Limit at Typ.250mA for appr.700s period after startup Ceramic Capacitor (CIN, COUT): 1.0 F or more (No Need of Noise Bypass Capacitor) APPLICATIONS TYPICAL APPLICATIONS Mobile Phones and Tablets, Digital Cameras, VDD VOUT VOUT Audio Devices, and Battery-powered RP122x VIN C C IN OUT Equipment RF Modules CE GND Clock Generator: VCO, PLL, etc. CE Control Noise-sensitive Devices: ADC, DAC Without a bypass capacitor for noise PACKAGE WLCSP-4-P8 WLCSP-4-P12 DFN(PLP)1010-4 0.64 x 0.64 x 0.36 (mm) 1.00 x 1.00 x 0.6 (mm) 0.64 x 0.64 x 0.26 (mm) 1 RP122x No.EA-403-210426 SELECTION GUIDE (1) The set output voltage and the auto-discharge function are user-selectable.
