FAN2560UC13X

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

The FAN2560UC13X is a linear low-dropout (LDO) voltage regulator manufactured by Fairchild Semiconductor, now part of onsemi. It features a split-supply architecture with separate bias and supply inputs to optimize performance. The device provides a fixed positive output voltage of 1.3V with a maximum current output of 350mA. It operates within an input voltage range supporting the LDO function and maintains a typical quiescent current of 11µA. The component is housed in a compact 5-WLCSP package measuring 0.96x1.33 mm, suitable for space-constrained portable applications.

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

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package integrity and pin alignment upon receipt. Check manufacturing date codes against project timelines as this part may be obsolete. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet to prevent soldering defects during assembly.

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

Select this regulator when a fixed 1.3V output is required with minimal external component count. The split-supply design benefits applications where bias voltage can be optimized separately from the main supply rail. Consider the 350mA current limit and thermal dissipation capabilities relative to the PCB copper area. The WLCSP package is ideal for high-density layouts but requires careful handling during surface mount assembly.

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

This component belongs to the FAN2560 series of LDO regulators designed for low-power applications. It represents a transition from traditional discrete regulator designs to integrated solutions with built-in protection. The UC13X suffix denotes the specific output voltage variant and packaging type within the broader family of split-supply LDOs offered by Fairchild Semiconductor.

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

Direct substitutes include other 1.3V fixed LDOs in 5-WLCSP packages with similar current ratings. Verify pin compatibility and thermal characteristics before substitution. Cross-reference with onsemi's current portfolio for updated equivalents if the original part is discontinued.
