The low 105 mV dropout voltage at the requirements of high performance, space-constrained 150 mA load improves efficiency and allows operation over a applications. wide input voltage range. The ADP150 is available in 14 fixed output voltage options, Using an innovative circuit topology, the ADP150 achieves ranging from 1.8 V to 3.3 V. ultralow noise performance without the necessity of an Short-circuit and thermal overload protection circuits prevent additional noise bypass capacitor, making it ideal for noise damage in adverse conditions. The ADP150 is available in tiny sensitive analog and RF applications. The ADP150 also 5-lead TSOT and 4-ball, 0.4 mm pitch WLCSP packages for the achieves ultralow noise performance without compromising smallest footprint solution to meet a variety of portable power PSRR or line and load transient performance. The ADP150 offers applications. the best combination of ultralow noise and quiescent current consumption to maximize battery life in portable applications. Rev.
