FAN2513S25X

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

The FAN2513S25X is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by onsemi, formerly Fairchild Semiconductor. It provides a fixed 2.5 V output with a maximum continuous current of 150 mA. The device operates within an input voltage range up to 6.5 V and features a typical dropout voltage of 2.5 mV at low currents, rising to a maximum of 180 mV at full load. It includes an enable control feature and thermal shutdown protection. The component is housed in a surface-mount SOT-23-5 package and supports operation from -40°C to +125°C.

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

Verify the specific manufacturer source, as production has transitioned from Fairchild Semiconductor to onsemi. Confirm the part status, as this component may be listed as obsolete or discontinued depending on the distributor. Ensure the datasheet matches the exact suffix X for tape and reel packaging requirements. Cross-reference the pinout and electrical specifications with the official onsemi documentation to avoid compatibility issues with legacy designs.

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

Select this regulator when a precise 2.5 V rail is required with moderate current demands up to 150 mA. Consider the SOT-23-5 package size for space-constrained PCB layouts. Evaluate the dropout voltage characteristics against the minimum input voltage available in the system. Verify that the thermal performance under expected load conditions remains within safe operating limits without additional heatsinking.
