BUxxSA4 series are high-performance CMOS LDO regulators with output current ability of up to 200-mA. These devices have excellent noise and load response characteristics despite of its low circuit current consumption of 40μA. They are most appropriate for various applications such as power supplies for logic IC, RF, and camera modules.

High Output Voltage Accuracy: ±0.6% (±15mV on VOUT<2.5V)
High Ripple Rejection: 70 dB (Typ, 1 kHz,)
Compatible with small ceramic capacitor (Cin=Cout=0.47 μF)
Low Current Consumption: 40 μA
Output Voltage ON/OFF control
Built-in Over Current Protection Circuit (OCP)
Built-in Thermal Shutdown Circuit (TSD)
Adopting ultra-small WLCSP UCSP50L1
