ADP172ACBZ-0.9-R7

ADP172ACBZ-0.9-R7 Description

The ADP172ACBZ-0.9-R7 from Analog Devices Inc. is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in compact, power-sensitive applications. This fixed-output regulator delivers a stable 0.9V at up to 300mA with an ultra-low quiescent current of 60 µA, making it ideal for battery-operated and portable devices. Its input voltage range extends up to 3.6V, ensuring compatibility with common power sources like Li-ion batteries. Packaged in a 4-lead WLCSP (Wafer-Level Chip-Scale Package) and supplied in tape-and-reel (TR) format, it is optimized for space-constrained designs.

ADP172ACBZ-0.9-R7 Features

• Low Power Consumption: Quiescent current of 60 µA and supply current of 260 µA (max) enhance efficiency in always-on applications.
• High PSRR: 73dB at 1kHz (dropping to 47dB at 100kHz) ensures excellent noise rejection for sensitive analog/digital loads.
• Robust Protection: Integrated safeguards include over-temperature shutdown, short-circuit protection, and UVLO (Under Voltage Lockout).
• Advanced Control: Features enable pin and soft-start for controlled power sequencing and inrush current mitigation.
• Miniaturized Form Factor: 4WLCSP package (1.2mm x 0.8mm) suits wearables, IoT, and handheld devices.
• Compliance: ROHS3 and REACH compliant, with MSL1 (Unlimited) moisture sensitivity for easy handling.

ADP172ACBZ-0.9-R7 Applications

• Portable Electronics: Smartphones, tablets, and wireless sensors benefit from its low Iq and small footprint.
• IoT/Wearables: Ideal for always-on subsystems (e.g., MCU cores, sensors) due to ultra-low power dissipation.
• Medical Devices: High PSRR and precision voltage regulation suit hearing aids and implantable monitors.
• Industrial Systems: Reliable performance in UVLO and over-temperature conditions makes it suitable for harsh environments.
