Analog Devices Inc. ADP150 Ultra-low Noise Linear Regulators

Analog Devices ADP150 features ultra-low noise, low dropout (LDO) linear regulators operating from 2.2V to 5.5V. ADP150's low 105mV dropout voltage at 150mA load increases efficiency and enables operation over a wide input voltage range. The ADP150 delivers ultra-low noise performance without compromising PSRR or line and load transient performance. The ADP150 regulators use an innovative circuit topology to achieve 9μV ultra-low noise performance without the need for an additional noise bypass capacitor. ADP150's circuit topology makes the regulators ideal for noise-sensitive analog and RF applications. Offering ultra-low noise and quiescent current consumption, ADP150 regulators help maximize battery life in portable applications. Designed for stable operation with tiny 1μF ± 30% ceramic input and output capacitors, ADP150 regulators meet the requirements of high-performance, space-constrained applications. The ADP150 regulators are ideal for mobile phones, digital cameras and audio devices, portable & battery-powered equipment, post-DC-to-DC regulation, portable medical devices, and RF, PLL, VCO and clock power supplies.
