Description
RP120 Series Low Input / Output 1.5 A Low Dropout Regulator OVERVIEW No.EA-585-230706 The RP120 is a very low dropout regulator which operates from input voltage as low as 0.768 V (@VSET = 0.6 V, VBIAS = 3.3 V, IOUT = 1.5 A). The LDO uses an internal low on-resistance (67 mΩ @VSET = 0.6 V, VBIAS = 3.3 V, IOUT = 1 A) NMOS transistor as the driver. The VBIAS pin provides the higher supply necessary for the LDO circuitry while the output current comes directly from the VIN input for high efficiency regulation. KEY BENEFITS  High PSRR, high output current, and fast response characteristics.  Suitable for sensitive sensors, high-quality audio, and RF devices.  Very small WLCSP package (1.2 mm x 0.8 mm x 0.29 mm). KEY SPECIFICATIONS TYPICAL APPLICATION Input Voltage Range : VIN = VSET + VDIFF to VBIAS (Ex. Min. 0.768 V @VSET = 0.6 V, VBIAS = 3.3 V, IOUT = 1.5 A) VBIAS = 2.4 V to 5.5 V Output Voltage Setting Range: Internal Fixed Type: 0.6 V to 2.0 V DC/DC Converter CBIAS CE Control CIN VBIAS VOUT RP120xxx1D CE VFB VIN GND COUT Adjustable Output Type: 0.6 V to 3.6 V Output Current: IOUTMAX = 1.5 A Supply Current: Typ. 35 µA Output Noise: Typ. 50 µVrms (VSET = 0.6 V) Power Supply Ripple Rejection: Typ. 95 dB (f = 1 kHz, Ripple in VIN) Typ. 60 dB (f = 100 kHz, Ripple in VIN) Dropout Voltage: Typ. 102 mV (IOUT = 1.5 A, VSET = 0.6 V, VBIAS = 3.3 V) Inrush Current Limit: Typ. 600 mA Short Circuit Current Protection: Typ. 600 mA Thermal Shutdown: Ty...
