The ADP150AUJZ-3.3-R7 is an Ultralow Noise CMOS Linear Regulator that operates from 2.2 to 5.5V and provides up to 150mA of output current. The low 105mV dropout voltage at 150mA 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. It offers the best combination of ultralow noise and quiescent current consumption to maximize battery life in portable applications. The regulator 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. Short-circuit and thermal overload protection circuits prevent damage in adverse conditions.
