The Analog Devices ADP150AUJZ-3.3-R7 is a 3.3V fixed-output, 150mA CMOS low-dropout linear regulator designed for ultra-low-noise and low-power applications. The ADP150 family operates from a 2.2V to 5.5V supply and is well suited for RF, PLL/VCO, audio, portable electronics, and post-DC/DC regulation. ADI currently lists the ADP150 family as PRODUCTION.
The exact part provides a 3.3V fixed output with up to 150mA output current. Initial output-voltage accuracy is ±1%, and the regulator remains stable with only 1µF ceramic input and output capacitors, without requiring a separate noise-bypass capacitor.
Output noise is only 9µV RMS, while power-supply rejection reaches 70dB at 10kHz, making the device especially attractive for noise-sensitive analog and RF signal chains.
Typical dropout voltage is 105mV at 150mA, while no-load ground current is only 10µA typical. At a 150mA load, typical operating ground current is approximately 220µA, and shutdown current is approximately 0.2µA typical.
Integrated functions include a logic-controlled enable, current limiting, short-circuit protection, thermal-overload protection, and undervoltage lockout. Typical current-limit threshold is approximately 260mA.
The exact ADP150AUJZ-3.3-R7 is supplied in a 5-lead TSOT package, specified from -40°C to +125°C, with marking code LEJ and 3,000 devices per reel. The standard A-grade part is distinct from ADI’s W-prefixed automotive-qualified versions.
