NCP170BMX320TCG

Product Overview

This Antrex Electronics technical summary describes the NCP170BMX320TCG from onsemi, a single-output linear regulator that produces a positive fixed 3.2V rail. The maximum input voltage is 5.5V, and the specified output current is 150mA. The regulator can be controlled through an enable function and includes over-current and over-temperature protection. Its quiescent current is 900 nA, and the junction temperature range is -40°C to 85°C. The device is supplied in a surface-mount 4-XDFN exposed-pad package, with supplier package designation 4-XDFN (1x1).

Key Features

• Single positive output fixed at 3.2V with 150mA current capability.
• Maximum input voltage is 5.5V.
• Enable control provides a means to disable the regulator output.
• Quiescent current is 900 nA.
• Protection features include over-current and over-temperature.
• Surface-mount 4-XDFN exposed-pad package, supplier package 4-XDFN (1x1).
• Operating junction temperature range is -40°C to 85°C.

Applications

• Regulated 3.2V rail for small digital subsystems.
• Switchable supply for sensor nodes or control modules.
• Fixed 3.2V supply for portable electronics.
• Enabled voltage domain in standby or sleep management.
• Compact regulator placement in space-limited board layouts using the 4-XDFN (1x1) package.

Design & Procurement Notes

When selecting this part, verify that the available input voltage does not exceed 5.5V and that the load current remains at or below 150mA. The fixed 3.2V output does not provide adjustable output selection, so system rail voltage must match this value. The enable control should be used to confirm desired power-up and power-down behavior in the final circuit. The 900 nA quiescent current supports low-power control paths, while the 4-XDFN exposed-pad package requires attention to thermal pad soldering and layout. The specified junction temperature range is -40°C to 85°C, and the supplied lifecycle status is Obsolete, so long-term availability should be considered in new designs.
