ADP170AUJZ-2.5-R7

The ADP170AUJZ-2.5-R7 is a low dropout (LDO) linear voltage regulator from AD(RoHS) designed to deliver up to 300mA of output current with a fixed 2.5V output voltage. It operates from an input voltage range of 1.6V to 3.6V, making it suitable for battery-powered and low-voltage applications. The device features a low dropout voltage of 66mV at 300mA load, which helps maintain regulation even when the input voltage is close to the output. The quiescent current is only 23µA at no load and 170µA at full load, contributing to extended battery life. The shutdown current is less than 1µA. The regulator offers excellent power supply rejection ratio (PSRR) of 73dB at 1kHz and 70dB at 10kHz, and low output noise of 30µV rms at 0.8V output. Output voltage accuracy is ±1% for fixed output options. The ADP170AUJZ-2.5-R7 is housed in a compact TSOT-5 package, which is surface mountable, ideal for space-constrained designs. It is part of the ADP170/ADP171 series, which offers up to 31 fixed output voltage options and an adjustable version. Applications include powering microcontrollers, sensors, and other low-power digital circuits where low noise and high efficiency are required.
