NCP4586DMU14TCG

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

The NCP4586DMU14TCG is a CMOS low dropout linear regulator manufactured by onsemi, featuring a fixed 1.4 V output voltage and a maximum continuous output current of 150 mA. It operates within an input voltage range of 1.7 V to 6.5 V and maintains high accuracy with ±1% tolerance at 25°C for outputs above 2 V. The device incorporates current fold-back protection and ensures stability when paired with 0.47 µF ceramic capacitors. Packaged in a compact UDFN-4 (1.0 x 1.0 mm) form factor, it supports surface mount assembly and functions reliably across an ambient temperature range of -40°C to +85°C.

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

Verify the specific ordering suffix 'DMU14TCG' to confirm the UDFN-4 package type, 1.4 V fixed output voltage, and compliance with lead-free manufacturing standards. Ensure the design accounts for the enable pin configuration appropriate for this variant. Confirm thermal dissipation requirements based on the PCB layout and ambient operating conditions before finalizing procurement specifications.

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

Select this component when a precise 1.4 V rail is required from a single-cell lithium battery or similar supply source. The low quiescent current makes it suitable for portable systems where standby power consumption must be minimized. Verify that the input voltage remains within the specified operational limits to prevent instability. Consider the thermal resistance of the UDFN-4 package when designing for high ambient temperatures or significant power dissipation scenarios.
