Overview
The ADP170AUJZ-1.2-R7 is a low voltage input, low quiescent current, low-dropout (LDO) linear regulator produced by Analog Devices Inc. This component is part of the ADP170 series, which is designed to operate from an input voltage range of 1.6 V to 3.6 V. The ADP170AUJZ-1.2-R7 is specifically configured to provide a fixed output voltage of 1.2 V. It is ideal for battery-operated portable equipment due to its low quiescent current of 23 µA at a 0 mA load and a low dropout voltage of 66 mV at 300 mA load, enhancing efficiency and allowing operation over a wide input voltage range.
