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

Verify the specific suffix 'S33X' confirms the fixed 3.3V output configuration and Bypass pin function on Pin 4. Confirm the manufacturer origin as Fairchild or onsemi, noting the acquisition history. Ensure the component status is checked for availability as older revisions may be discontinued. Validate RoHS compliance requirements against the specific manufacturing date code.

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

Select this component when a stable 3.3V rail is required for sensitive analog or digital loads in space-constrained designs. The SOT-23-5 package minimizes board area compared to larger regulators. Consider the 200mA current limit for moderate load requirements. The wide capacitor tolerance simplifies bill-of-materials selection by allowing flexible choice between ceramic and tantalum types without compromising stability.

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

This part belongs to the FAN2514/FAN2515 family of CMOS LDO regulators designed for cost-effective performance in GSM, TDMA, and CDMA cellular handsets. The family distinguishes models by Pin 4 functionality: Adjustable (FAN2514), Bypass (FAN2514-XX), or Error Flag (FAN2515-XX). The FAN2514S33X specifically utilizes the Bypass configuration for noise reduction.

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

Pin-compatible replacements within the same family include other fixed-voltage variants such as FAN2514S25X, FAN2514S28X, or FAN2514S30X if different voltage levels are needed. Cross-family compatibility should be verified via official datasheets before substitution.
