The ADP151AUJZ-3.3-R7 is an Ultralow Noise CMOS Linear Regulator that 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, it achieves ultralow noise performance without the necessity of an additional noise bypass capacitor, making it ideal for noise sensitive analogue and RF applications. It also achieves ultralow noise performance without compromising PSRR or line and load transient performance. The low 265µA of quiescent current at 200mA load makes the ADP151 suitable for battery-operated portable equipment. This also includes an internal pull-down resistor on the EN input. It 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.
