Ultralow Noise, 150 mA CMOS Linear Regulator
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.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
This product has individual evaluations boards at specific voltages or with specific features as well as the RedyKit&tm;. The RedyKit simplifies product evaluation by providing two assembled and tested evaluation boards, plus a full set of product (voltage) options for an IC regulator. All the IC options come sorted and stored in the kit with the Analog Devices part number clearly printed on each antistatic zip-top bag.
Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
