NCP4586DMU15TCG

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

The NCP4586DMU15TCG is a fixed-output low dropout linear regulator from onsemi, providing a nominal 1.5 V output with a maximum current capability of 150 mA. It operates within an input voltage range of 1.7 V to 6.5 V and features very low dropout characteristics, typically 320 mV at full load. The device incorporates high power supply rejection ratio (PSRR) of 80 dB at 1 kHz and maintains ±1% output voltage accuracy at 25°C for outputs above 2 V. It includes current fold-back protection and is stable with small ceramic capacitors. The component is housed in a compact UDFN-4 package.

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

Verify the specific suffix 'DMU' confirms the UDFN-4 package and '15' indicates the 1.5 V fixed output voltage. Confirm RoHS compliance status as indicated by the 'CG' suffix. Ensure the enable pin configuration matches system requirements, as this variant belongs to the standard series without auto-discharge features unless specified otherwise in detailed ordering tables.

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

Select this regulator when a precise 1.5 V rail is required from a variable input source between 1.7 V and 6.5 V. Consider its low quiescent current for battery life extension. Verify that the thermal dissipation capabilities of the UDFN-4 package are sufficient for the expected power load and ambient temperature conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the NCP4586 family of low dropout regulators, which offers multiple output voltages and package options including SC-82AB and SOT-23-5. The DMU suffix specifically denotes the UDFN-4 footprint, distinguishing it from other physical form factors within the same electrical specification family.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct replacements include other NCP4586 variants with different output voltages or packages, such as NCP4586DMU25TCG for 2.5 V output in the same package. Cross-brand equivalents require matching input/output voltage ranges, current capacity, and package dimensions.
