ADP1761ACPZ-R7

ADP1761ACPZ-R7 Description

The ADP1761ACPZ-R7 from Analog Devices Inc. is a high-performance, 1A adjustable linear voltage regulator designed for precision power management in compact, power-sensitive applications. With an input voltage range up to 1.98V and an adjustable output from 0.5V to 1.5V, it delivers stable, low-noise power for advanced digital and analog circuits. Packaged in a 16-lead LFCSP (4x4mm) and supplied in tape & reel (TR), this regulator is optimized for surface-mount assembly in space-constrained designs. Its low dropout voltage (53mV at 1A) and high PSRR (67dB at 10kHz) ensure efficient operation even with tight input-output differentials, making it ideal for noise-sensitive systems.

ADP1761ACPZ-R7 Features

• Adjustable Output (0.5V–1.5V): Fine-tuned voltage regulation for diverse load requirements.
• High Efficiency: Ultra-low dropout (0.053V @ 1A) minimizes power loss.
• Advanced Control & Protection: Features enable pin, power-good signal, and soft-start for controlled power sequencing, alongside current limit and thermal overload protection.
• Low Quiescent Current (8mA): Optimizes battery life in portable applications.
• Excellent Noise Rejection: 67dB PSRR at 10kHz (declining to 35dB at 1MHz) ensures clean power delivery.
• Robust Packaging: MSL 3 (168 hours) rated, ROHS3/REACH compliant, suitable for industrial environments.

ADP1761ACPZ-R7 Applications
