ADP162AUJZ-2.8-R7

Product Overview

The Analog Devices Inc. ADP162AUJZ-2.8-R7 is a positive fixed-output linear voltage regulator for single-output 2.8 V applications. It uses a surface-mount TSOT-23-5 package and provides up to 150 mA output current from an input voltage up to 5.5 V. The regulator includes an enable control and integrates over-current, over-temperature, and under-voltage lockout protections. Quiescent current is 1.25 µA, and maximum supply current is 65 µA.

Key Features

• Positive fixed output: 2.8 V with one regulator channel.
• Input voltage maximum: 5.5 V.
• Output current: 150 mA.
• Quiescent current: 1.25 µA; maximum supply current: 65 µA.
• Enable control for output rail management.
• Integrated protection: over-current, over-temperature, and under-voltage lockout.
• Operating temperature range: -40°C to 125°C.
• Surface-mount TSOT-23-5 package.

Applications

• Fixed 2.8 V rail generation for low-current electronic circuitry.
• Enable-controlled 2.8 V power delivery to compact subsystems.
• Surface-mount linear regulation where current, thermal, and UVLO protections are required.

Design & Procurement Notes

When selecting the ADP162AUJZ-2.8-R7, confirm that the system input voltage remains within the 5.5 V maximum and that the load current does not exceed 150 mA. Because the output is fixed at 2.8 V, the regulator cannot be adjusted to another voltage. The enable feature should be incorporated into the control logic if the rail needs to be switched on or off. The 1.25 µA quiescent current and 65 µA maximum supply current are relevant for power budgets in low-current 2.8 V rails. The integrated over-current, over-temperature, and under-voltage lockout protections support basic fault containment, while the -40°C to 125°C operating range and TSOT-23-5 footprint should be verified against the board's thermal and layout constraints.
