ADP150:  Ultralow Noise, 150 mA CMOS Linear Regulator

Product Details


The ADP150 is an ultralow noise (9 μV), low dropout, linear regulator that operates from 2.2 V to 5.5 V and provides up to 150 mA of output current. The low 105 mV dropout voltage at 150 mA load improves efficiency and allows operation over a wide input voltage range.

Using an innovative circuit topology, the ADP150 achieves ultralow noise performance without the necessity of an additional noise bypass capacitor, making it ideal for noise sensitive analog and RF applications. The ADP150 also achieves ultralow noise performance without compromising PSRR or line and load transient performance. The ADP150 offers the best combination of ultralow noise and quiescent current consumption to maximize battery life in portable applications. The ADP150 is specifically designed for stable operation with tiny 1 μF ± 30% ceramic input and output capacitors to meet the requirements of high performance, space-constrained applications.

The ADP150 is available in 14 fixed output voltage options, ranging from 1.8 V to 3.3 V. Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP150 is available in tiny 5-lead TSOT and 4-ball, 0.4 mm pitch WLCSP packages for the smallest footprint solution to meet a variety of portable power applications.
