NCP170AXV210T2G

Product Overview

The onsemi NCP170AXV210T2G is a surface-mount fixed-output linear regulator for generating a single positive output rail from input voltages up to 5.5 V. It provides a 2.1 V regulated output with a rated output current of 150 mA and a quiescent current of 900 nA. The device features an enable control and over-current and over-temperature protection. It is packaged in SOT-563 and is specified for operation over a junction temperature range of -40°C to 85°C.

Key Features

• Fixed 2.1 V positive output from a single regulator channel
• Maximum input voltage of 5.5 V
• Output current rating of 150 mA
• Quiescent current of 900 nA
• Enable control feature
• Over-current and over-temperature protection
• SOT-563 surface-mount package
• Operating junction temperature range of -40°C to 85°C

Applications

• Generating a fixed 2.1 V positive supply rail for low-current circuitry in compact surface-mount assemblies.
• Enabling or disabling a single regulator output during local power sequencing in small electronic modules.
• Providing a protected 150 mA linear output where over-current and over-temperature protection are relevant design considerations.

Design & Procurement Notes

When selecting the NCP170AXV210T2G, confirm that the available input voltage remains within the 5.5 V maximum and that the load current does not exceed 150 mA. The output is fixed at 2.1 V, so it is suitable only for circuits requiring that exact voltage. The enable control should be incorporated into the power architecture if selective activation is needed. Because the temperature specification is given as a junction range, board layout, heat dissipation, and ambient conditions should be evaluated for thermal margin. The SOT-563 surface-mount package should be checked against the required footprint and assembly process, and the over-current and over-temperature protection should be verified against the intended fault-handling strategy.
