NCP120AMX120TCG

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The NCP120AMX120TCG is a fixed-output low-dropout linear regulator manufactured by onsemi, providing a stable 1.2 V output with a maximum continuous current of 150 mA. It operates within an input voltage range of 800 mV to 5.5 V and features an ultra-low dropout voltage of 75 mV at full load. The device includes active discharge functionality for the output rail and incorporates comprehensive protection mechanisms such as overcurrent limiting, thermal shutdown, and under-voltage lockout. Designed for surface-mount installation in XDFN-6 packages, it supports industrial operating temperatures from -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm package integrity and pin alignment against the XDFN-6 specification before integration. Review manufacturer obsolescence notices for transition timelines. Ensure compatibility with existing PCB footprint and soldering profiles. Validate electrical parameters against updated datasheet revisions prior to final design approval.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator when ultra-low dropout voltage is critical for maintaining efficiency near minimum input thresholds. The 150 mA output capacity suits moderate load applications without requiring external pass transistors. Active discharge capability simplifies system power sequencing by preventing floating outputs. Verify that the required output voltage matches the fixed 1.2 V configuration, as adjustable variants are not available in this specific part number.
