ADP151ACBZ-3.3-R7 Datasheet PDF - ADI

●The ADP151 series low-dropout (LDO) Linear Regulator operates from 2.2 to 5.5V and provides up to 200mA of output current. The low 140mV dropout voltage at 200mA load improves efficiency and allows operation over a wide input voltage range. Using an innovative circuit topology, the device achieves ultralow noise performance without the necessity of a bypass capacitor. The device also achieves ultralow noise performance without compromising PSRR or transient line and load performance. The low 265µA of quiescent current at 200mA load makes the device suitable for battery-operated portable equipment. The device also includes an internal pull-down resistor on the EN input. The device is specifically designed for stable operation with tiny 1µF, ±30% ceramic input and output capacitors to meet the requirements of high performance, space constrained applications. The device is capable of 16 fixed output voltage options, ranging from 1.1 to 3.3V.
