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

Verify component status before design finalization as this specific part number is listed as discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets if immediate procurement is required. Ensure that any replacement components maintain equivalent electrical characteristics and pin compatibility for existing layouts.

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

Select this regulator for applications requiring low noise and high PSRR in space-constrained designs. The slow slew rate option is ideal for camera sensors and other sensitive circuits where rapid voltage transitions must be avoided. Verify that the PCB layout supports the XDFN-4 package thermal requirements for optimal performance.

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

This component belongs to the NCP115 series of LDO regulators designed for portable electronics. The 'C' suffix indicates a slow slew rate variant, while 'MX' denotes the XDFN-4 surface mount package. The '100' specifies the 1.0 V fixed output voltage. This series is engineered for low-power consumption and high accuracy in battery-operated systems.

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

Consult the datasheet discontinuation notice for recommended alternatives. Potential substitutes include other NCP115 variants with different output voltages or slew rates, such as NCP115AMX100TCG (normal slew rate) or NCP115CMX120TCG (different voltage). Ensure functional equivalence regarding package type and electrical specifications.
