The ADP122ACPZ-3.3-R7 from Analog Devices is a low quiescent current, low dropout linear regulator designed for portable and battery-powered applications. It accepts an input voltage range of 2.3 V to 5.5 V and can deliver a maximum output current of 300 mA.
Key electrical features include a very low dropout voltage of 85 mV at a 300 mA load, improving efficiency. The quiescent current is as low as 45 µA at no load and less than 1 µA in shutdown mode, making it ideal for power-sensitive devices. It offers excellent PSRR performance of 60 dB at 100 kHz and is optimized for stable operation with small 1.0 µF ceramic capacitors.
This regulator is available in fixed and adjustable output voltage versions. The ADP122 series offers up to 31 fixed output voltage options, while the ADP123 is the adjustable version with an output range of 0.8 V to 5.0 V. The ADP122ACPZ-3.3-R7 specifically refers to a fixed 3.3V output version.
The device includes current limit and thermal overload protection for enhanced reliability. It is offered in compact packages such as 5-lead TSOT and 6-lead 2 mm × 2 mm LFCSP, suitable for space-constrained designs. Mounting is typically surface mount.
