Technical Support www.analog.com FEATURES Ultra low noise: 9 μV rms, independent of VOUT No additional noise bypass capacitor required Stable with 1 μF ceramic input and output capacitors Maximum output current: 150 mA Input voltage range: 2.2 V to 5.5 V Low quiescent current IGND = 10 μA with zero load Low shutdown current: <1 μA Low dropout voltage: 105 mV @ 150 mA load Initial output voltage accuracy: ±1% Up to 14 fixed output voltage options: 1.8 V to 3.3 V PSRR performance of 70 dB at 10 kHz Current limit and thermal overload protection Logic-controlled enable 5-lead TSOT package 4-ball, 0.8 mm × 0.8 mm, 0.4 mm pitch WLCSP APPLICATIONS Mobile phones Digital camera and audio devices Portable and battery-powered equipment Post dc-to-dc regulation Portable medical devices RF, PLL, VCO, and clock power supplies TYPICAL APPLICATION CIRCUITS NC = NO CONNECT 1 2 3 5 4 COUT 1µF CIN 1µF VOUT = 1.8V VIN = 2.3V VOUT NC VIN GND EN OFF ON Figure 1. 5-Lead TSOT with Fixed Output Voltage, 1.8 V VIN VOUT 12 EN GND COUT 1µF CIN 1µF VOUT = 1.8V VIN = 2.3V TOP VIEW (Not to Scale) A B OFF ON Figure 2. 4-Ball WLCSP with Fixed Output Voltage, 1.8 V GENERAL DESCRIPTION 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. |
