ADP151AUJZ-1.5-R7

Product Overview

The ADP151AUJZ-1.5-R7 from Analog Devices Inc. is a surface-mount linear voltage regulator in a TSOT-23-5 package. It provides a positive, fixed 1.5 V output from a single regulator, with a maximum input voltage of 5.5 V and a rated output current of 200 mA. The device includes an enable control feature and protection against overcurrent, overtemperature, and under-voltage lockout. Its specified operating temperature range is -40°C to 125°C, and its quiescent current is 20 µA, with a maximum supply current of 350 µA.

Key Features

• Positive fixed 1.5 V output from a single linear regulator
• Maximum input voltage of 5.5 V and output current rating of 200 mA
• Enable control feature for externally controlled output operation
• Overcurrent, overtemperature, and under-voltage lockout protection
• Quiescent current of 20 µA and maximum supply current of 350 µA
• Surface-mount TSOT-23-5 package for compact board layouts
• Operating temperature range from -40°C to 125°C

Applications

• Supplying a fixed 1.5 V rail to low-voltage circuitry in compact surface-mounted electronic assemblies
• Controlled enable or disable operation of a single regulator output in power-managed designs
• Regulated power delivery in systems that require overcurrent, overtemperature, and under-voltage protection

Design & Procurement Notes

Designers should verify that the available input voltage does not exceed 5.5 V and that the required load current remains within the 200 mA output rating. The fixed 1.5 V output means the regulator is suitable only where that voltage is acceptable, and the enable control can be used to gate the output under system control. The TSOT-23-5 surface-mount package supports compact layouts, while the specified -40°C to 125°C range and protection features should be considered alongside thermal, input, and load conditions in the final design.
