ADP150ACBZ-2.5-R7

Product Overview

ADP150ACBZ-2.5-R7 from Analog Devices Inc. is a single-output linear voltage regulator that provides a fixed positive 2.5 V rail at up to 150 mA. The device accepts an input voltage up to 5.5 V and specifies a maximum dropout of 0.16 V at 150 mA. It is offered in a 4-WFBGA/WLCSP package with a 0.76 mm by 0.76 mm body and surface-mount construction. The device includes enable control and protection functions for over-current, over-temperature, and under-voltage lockout.

Key Features

• Fixed positive 2.5 V output with 150 mA output current
• Maximum input voltage of 5.5 V
• Maximum dropout voltage of 0.16 V at 150 mA
• Quiescent current of 22 µA
• Maximum supply current of 320 µA
• Enable control feature
• Over-current, over-temperature, and under-voltage lockout protection features
• Operating temperature of -40°C to 125°C
• 4-WFBGA/WLCSP surface-mount package with 0.76 mm by 0.76 mm body

Applications

• Deriving a fixed 2.5 V rail from an input supply of up to 5.5 V
• Using the enable control feature to manage regulator activation in power-sequenced designs
• Supplying low-current 2.5 V power to analog or digital circuit blocks
• Implementing surface-mount 2.5 V regulation in assemblies with limited board area

Design & Procurement Notes

When selecting this regulator, confirm that the input voltage remains at or below 5.5 V and that headroom exceeds 0.16 V at the required 150 mA load. The fixed 2.5 V output does not support adjustment, so downstream circuitry must require that exact rail. The enable control feature should be considered in power-up sequencing. Protection features and the -40°C to 125°C operating range should be checked against the intended environment. The 4-WFBGA/WLCSP package requires surface-mount assembly and board space planning for the 0.76 mm by 0.76 mm body.
