The ADP123AUJZ-R7 from Analog Devices is a low quiescent current, low dropout linear regulator designed for portable and battery-powered applications. It operates from an input voltage range of 2.3 V to 5.5 V and can deliver up to 300 mA of output current. The device features a very low dropout voltage of 85 mV at a 300 mA load, improving efficiency.
This adjustable version allows the output voltage to be set between 0.8 V and 5.0 V using an external voltage divider. Key electrical characteristics include a typical quiescent current of 45 µA at no load and a low shutdown current of less than 1 µA. It also offers excellent PSRR performance of 60 dB at 100 kHz and includes current limit and thermal overload protection.
The ADP123AUJZ-R7 is optimized for stable operation with small 1.0 µF ceramic capacitors. It is supplied in a compact 5-lead TSOT-23-5 package, suitable for space-constrained applications. The regulator is controlled via a logic-level enable pin.
Applications for this device include digital cameras, audio devices, portable equipment, automatic meter reading, GPS units, medical instrumentation, and point-of-sale equipment.
