ADP150AUJZ-3.3-R7

Product Overview

The ADP150AUJZ-3.3-R7 from Analog Devices Inc. is a positive fixed-output linear regulator in a compact surface-mount package. It provides a 3.3 V output at up to 150 mA, with a maximum input voltage of 5.5 V and a dropout voltage of 0.16 V at 150 mA. The device includes an enable control and protection features such as over-current, over-temperature, and under-voltage lockout. It operates over a temperature range of -40°C to 125°C and uses a TSOT-23-5 package.

Key Features

• Single positive fixed regulator with a 3.3 V output and 150 mA output current.
• Maximum input voltage of 5.5 V and dropout voltage of 0.16 V at 150 mA.
• Low 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 and protection against over-current, over-temperature, and under-voltage lockout.
• Surface-mount TSOT-23-5 package with operating temperature range of -40°C to 125°C.

Applications

• Regulated 3.3 V rail for compact sensor or control modules.
• Enable-controlled supply sequencing for low-current logic or interface boards.
• Noise-sensitive analog circuits where supply rejection between 10 kHz and 100 kHz is useful.

Design & Procurement Notes

For design and selection review, confirm that the fixed 3.3 V output matches the required rail and that the input voltage stays below 5.5 V while maintaining the dropout margin needed at the intended load current. Evaluate the enable control and protection behavior against system power sequencing and fault conditions. Because the device is a 150 mA linear regulator in a TSOT-23-5 package, PCB copper area and ambient temperature should be considered when dissipation approaches the operating temperature limit. Verify the footprint and pinout during layout, and compare quiescent and supply current values against standby power budgets.
