Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes
Verify the specific suffix 'S' indicates the SOT-23-5 package variant rather than the CSP or XDFN options listed in the general datasheet. Confirm RoHS compliance status and ensure the ordering code matches the required 3.3 V fixed output specification before finalizing procurement.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes
Select this component when low noise performance is critical for sensitive analog or RF sections. Ensure the PCB layout supports the recommended 1 µF ceramic output capacitor for stability. Verify that the maximum junction temperature rating aligns with the system's thermal environment.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context
This part belongs to the NCP161 family of ultra-low noise LDO regulators from onsemi. The series offers various output voltages and packaging options including WLCSP4, XDFN4, and SOT-23-5. It is engineered to provide high PSRR and minimal quiescent current for portable electronic applications.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations
