Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for FAN1086S25X

FAN1086S25X

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

The FAN1086S25X is a fixed-output low-dropout (LDO) linear regulator manufactured by onsemi. It provides a fixed output voltage of 2.5V with a maximum continuous output current of 1.5A. The device features a maximum input voltage rating of 7.5V and operates within an ambient temperature range of -40°C to +125°C. It utilizes a TO-263-3 (D2PAK) surface-mount package. Internal protection mechanisms include thermal shutdown and current limiting to safeguard the component under fault conditions.

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

Verify the specific suffix 'S' against official datasheets, as standard NCP/FAN series often use 'M' or 'T' for D2PAK/TO-263 packages. Confirm availability status, as many FAN1086 variants are discontinued. Ensure the selected substitute matches the 2.5V fixed output and 1.5A current capability. Cross-reference pinouts between legacy Fairchild and current onsemi documentation to prevent mounting errors.

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

Select this component when a stable 2.5V rail is required at up to 1.5A from a source not exceeding 7.5V. The TO-263 package offers superior thermal dissipation compared to smaller SOT packages. Consider the dropout voltage specifications relative to the minimum input voltage expected in the application. Verify that the load transient requirements align with the internal compensation of the LDO.
