The ADP151 is an ultralow noise, low dropout (LDO) linear The ADP151 also includes an internal pull-down resistor on regulator that operates from 2.2 V to 5.5 V and provides up to the EN input. 200 mA of output current. The low 135 mV dropout voltage at The ADP151 is specifical y designed for stable operation with 200 mA load improves efficiency and al ows operation over a tiny 1 µF, ±30% ceramic input and output capacitors to meet wide input voltage range. the requirements of high performance, space constrained Using an innovative circuit topology, the ADP151 achieves applications. ultralow noise performance without the necessity of a bypass The ADP151 is capable of 16 fixed output voltage options, capacitor, making the device ideal for noise sensitive analog ranging from 1.1 V to 3.3 V. and RF applications. The ADP151 also achieves ultralow noise performance without compromising the power supply rejection Short-circuit and thermal overload protection circuits prevent ratio (PSRR) or transient line and load performance. The low damage in adverse conditions. The ADP151 is available in tiny 265 μA of operating supply current at 200 mA load makes the 5-lead TSOT, 6-lead LFCSP, and 4-ball, 0.4 mm pitch, halide- ADP151 suitable for battery-operated portable equipment. free WLCSP packages for the smal est footprint solution to meet a variety of portable power application requirements.
