Datasheet CMOS LDO Regulators for Automotive 1ch 200mA CMOS LDO Regulators BUxxJA2VG-C series General Description Key Specifications BUxxJA2VG-C series are high-performance CMOS LDO Input Power Supply Voltage Range: 1.7V to 6.0V regulators with output current ability of up to 200mA. The Output Current Range: 0 to 200mA SSOP5 package can contribute to the downsizing of the set. Operating Temperature Range: -40C to +125C These devices have excellent noise and load response Output Voltage Lineup: 1.0V to 3.3V characteristics despite of its low circuit current consumption Output Voltage Accuracy: 2.0% of 33A. They are most appropriate for various applications Circuit Current: 33A(Typ) such as power supplies for radar modules and camera Standby Current: 0A (Typ) modules. Package W(Typ) x D(Typ) x H(Max) Features SSOP5 2.90mm x 2.80mm x 1.25mm (Note 1) AEC-Q100 qualified High Output Voltage Accuracy: 2.0% (In all recommended conditions) High Ripple Rejection: 68 dB (Typ, 1kHz) Compatible with small ceramic capacitor (Cin=Cout=0.47F) Low Current Consumption: 33A Output Voltage ON/OFF control Built-in Over Current Protection Circuit (OCP) Built-in Thermal Shutdown Circuit (TSD) Package SSOP5 is similar to SOT23-5(JEDEC) (Note 1) Grade1 Applications Automotive Radar modules Automotive Camera modules Typical Application Circuit Vin VOUT VIN Vout Cin Cout BUxxJA2VG-C On STBY Off GND Figure 1.

AMP Error AMP AMP amplifies electric signal and drives output power transistor. When output current exceeds current ability, OCP restricts Output OCP Over Current Protection Current. When Junction temperature rise and exceed Maximum junction TSD Thermal Shutdown temperature, TSD turns off Output power transistor. www.rohm.com TSZ02201-0G5G0A300040-1-2 2014 ROHM Co., Ltd.
