ADP150AUJZ-2.5-R7

Product Overview

The ADP150AUJZ-2.5-R7 from Analog Devices Inc. is a fixed positive linear voltage regulator intended for compact surface-mount power paths. It provides a 2.5 V output from an input voltage up to 5.5 V, with a rated output current of 150 mA. The device uses a TSOT-23-5 package and includes an enable control, along with over-current, over-temperature, and under-voltage lockout protection. Its specified dropout is 0.16 V at 150 mA, and its quiescent current is 22 µA, supporting low-power regulation in space-constrained designs.

Key Features

• Fixed 2.5 V positive output from a single regulator channel
• Input voltage specified up to 5.5 V
• Rated output current of 150 mA
• Voltage dropout specified at 0.16 V when delivering 150 mA
• Quiescent current of 22 µA and maximum supply current of 320 µA
• Enable control and protection for over-current, over-temperature, and UVLO conditions
• Surface-mount TSOT-23-5 package with operating temperature range from -40°C to 125°C

Applications

• Regulating a 2.5 V rail for low-current mixed-signal or digital subsystems
• Providing local power to battery-powered portable electronics where quiescent current matters
• Supplying sensors, transceivers, or other board-level loads that need a fixed voltage
• Enabling or disabling a 2.5 V supply rail during system power sequencing

Design & Procurement Notes

For design selection, confirm that the available input voltage remains within the specified 5.5 V maximum and that the load current does not exceed 150 mA. The 0.16 V dropout at 150 mA should be included in headroom calculations, especially when the input is close to 2.5 V. The enable control can be used to manage regulator state, while the specified over-current, over-temperature, and UVLO protections support fault containment. The TSOT-23-5 surface-mount package and -40°C to 125°C operating range should be checked against PCB layout, thermal dissipation, and ambient conditions.
