ADP150ACBZ-1.8-R7

Product Overview

The ADP150ACBZ-1.8-R7 from Analog Devices Inc. is a single-output linear regulator intended for compact surface-mount power management. The device provides a fixed positive 1.8 V output from an input voltage up to 5.5 V and can deliver up to 150 mA. It is housed in a 4-WLCSP package with a 0.76 x 0.76 mm body, supporting dense board layouts. The regulator includes an enable control feature and protection against over current, over temperature, and under voltage lockout, with an operating temperature range of -40°C to 125°C.

Key Features

• Fixed positive 1.8 V single-output linear regulation
• Maximum input voltage of 5.5 V and output current of 150 mA
• Quiescent current of 22 µA and maximum supply current of 320 µA
• Power supply rejection ratio of 70 dB to 55 dB from 10 kHz to 100 kHz
• Enable control with over current, over temperature, and UVLO protection
• 4-WLCSP surface-mount package with 0.76 x 0.76 mm dimensions

Applications

• Battery-powered portable electronics requiring a compact 1.8 V supply rail
• Embedded modules and microcontroller subsystems using a fixed low-voltage regulator
• Space-constrained boards where a small WLCSP regulator is suitable
• Power sequencing or controlled enable operation in single-rail subsystems

Design & Procurement Notes

Designers selecting this regulator should confirm that the 1.8 V fixed output matches the load requirement and that the input voltage remains within the 5.5 V maximum rating. The 150 mA output current limit should be compared with peak load current to avoid entering over-current protection. The enable feature can be used to place the device in a controlled state, while the 22 µA quiescent current supports low-power standby considerations. The 4-WLCSP package requires surface-mount assembly and adequate layout care for thermal and electrical performance across the -40°C to 125°C operating range.
