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

Verify the specific ordering suffix 'MX' corresponds to the UDFN4 package and 'TCG' indicates lead-free status. Confirm that the 'A' designation in the part number ensures the inclusion of the active output discharge feature. Cross-reference the marking code '3' with the manufacturer's official documentation to validate the 2.85 V output option before finalizing procurement.

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

Select this component for space-constrained designs requiring a compact UDFN4 footprint. Ensure the application utilizes ceramic output capacitors with X5R or X7R dielectrics to maintain stability. Verify that the input voltage remains above the minimum threshold of 1.7 V and consider the thermal resistance characteristics if operating near maximum load currents.

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

Does the NCP114AMX285TCG include an active output discharge function?

Yes, devices with the 'A' prefix in the part number, such as NCP114AMX285TCG, are equipped with an active output discharge transistor that activates when the Enable pin is driven low.

What is the minimum required output capacitor value for stability?

The device is stable with a minimum effective capacitance of 0.22 µF. However, a 1 µF ceramic capacitor with X5R or X7R dielectric is recommended for optimal performance.
