ADP151ACPZ-3.3-R7 Description

Short technical summary and product information.

The ADP151ACPZ-3.3-R7 from Analog Devices is a CMOS linear regulator designed for ultralow noise applications. It provides a stable 3.3V output voltage with a maximum current capability of 200mA, drawing only 265µA of quiescent current at full load. The input voltage range is from 2.2V to 5.5V, with a low dropout voltage of 135mV at 200mA.

This regulator features no requirement for a noise bypass capacitor, making it suitable for sensitive analog and RF circuits. It is stable with small 1µF ceramic input and output capacitors. Key electrical characteristics include an initial accuracy of ±1% and accuracy over line, load, and temperature of ±2.5%. It also offers a PSRR of 70dB at 10kHz and includes current-limit and thermal overload protection.

The ADP151ACPZ-3.3-R7 is supplied in a 6-lead LFCSP package, designed for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). The device is AEC-Q100 qualified, indicating suitability for automotive applications.

Applications include power supplies for RF, voltage-controlled oscillators (VCOs), and phase-locked loops (PLLs), as well as mobile phones, digital cameras, portable equipment, and post DC-to-DC regulation.
