ADP122ACPZ-3.3-R7 Description

Short technical summary and product information.

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 provides a stable 3.3V output voltage and can deliver up to 300mA of current.

 

Key electrical specifications include a wide input voltage range from 2.3V to 5.5V, a low dropout voltage of 85mV at 300mA, and very low quiescent current of 45µA at no load. The regulator also features excellent PSRR performance of 60dB at 100kHz, current limit, and thermal overload protection.

 

This device is optimized for stable operation with small 1.0µF ceramic capacitors, making it suitable for space-constrained designs. It is available in a compact 6-lead LFCSP-UD (2x2) package, suitable for surface mount applications.

 

Applications include digital cameras, audio devices, portable equipment, and medical instrumentation where low power consumption and small size are critical.
