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

Verify the manufacturer designation, as Fairchild Semiconductor assets were acquired by onsemi. Confirm the specific suffix UC13X corresponds to the 1.3V fixed output and 4WLCSP package variant. Ensure RoHS compliance status matches project requirements. Check for obsolescence notices or lifecycle changes associated with the transition from Fairchild to onsemi product lines before finalizing procurement.

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

Select this component when a low input voltage range starting at 1.65V is required alongside a fixed 1.3V output. The 300mA current rating suits moderate load digital circuits. Consider the 4WLCSP package for space-constrained designs. Verify that the 75µA quiescent current meets system standby power specifications. Ensure the operating temperature range of -40°C to 85°C aligns with the environmental conditions of the target application.

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

The FAN2564 series belongs to the family of low VIN LDO regulators optimized for digital applications. These components are characterized by their ability to regulate efficiently from very low input voltages. The UC13X designation specifically identifies the 1.3V output version within this lineup. This series is commonly used in portable electronics where battery life and small form factors are critical design constraints.

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

Check onsemi documentation for direct cross-references within the FAN2564 series. Verify if other suffixes offer different output voltages or packages while maintaining identical electrical characteristics. Confirm pinout compatibility before substituting with similar LDO regulators from other manufacturers.
