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 ultralow ranging from 1.8 V to 3.3 V. noise performance without the necessity of an additional noise Short-circuit and thermal overload protection circuits prevent bypass capacitor, making it ideal for noise sensitive analog and damage in adverse conditions. The ADP150 is available in tiny RF applications. The ADP150 also achieves ultralow noise 5-lead TSOT and 4-ball, 0.4 mm pitch WLCSP packages for the performance without compromising PSRR or line and load smallest footprint solution to meet a variety of portable power transient performance. The ADP150 offers the best combination applications. of ultralow noise and quiescent current consumption to maximize battery life in portable applications. Rev.
