FAN1581T15

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

The FAN1581T15 is a linear voltage regulator IC from onsemi, providing a fixed positive output of 1.5V with a maximum continuous current capability of 5A. It utilizes a TO-252-5 (DPAK) surface-mount package. The device operates with an input voltage range up to 7V and features a typical dropout voltage of 0.4V at full load. Key electrical parameters include a quiescent current of 6 mA and a power supply rejection ratio (PSRR) of 80 dB at 120 Hz. It includes integrated over-current and over-temperature protection and functions within an operating temperature range of 0°C to 125°C.

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

Verify the specific suffix T15 against official datasheets to confirm the 1.5V fixed output variant. Confirm package type matches TO-252-5 requirements. Check current manufacturing status as legacy parts may be obsolete or subject to last-time buys. Ensure compatibility with existing PCB footprints and thermal management designs before procurement.

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

Select this component when a stable 1.5V rail is required at high currents with minimal voltage drop. Compare dropout characteristics against input supply variations. Evaluate thermal dissipation capabilities in the target enclosure. Consider alternative packages if higher power handling is needed.

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

This part belongs to the FAN1581 family of ultra-low dropout linear regulators designed by onsemi (formerly Fairchild Semiconductor). The series includes adjustable versions and other fixed voltages like 1.2V and 2.5V. These regulators are engineered for high-efficiency power delivery in digital systems requiring precise voltage regulation under heavy dynamic loads.

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

Direct substitutes include FAN1581MX (adjustable, TO-263) and FAN1581D25X (fixed 2.5V, TO-252-5). Verify pinout compatibility and thermal resistance differences when replacing with adjacent family members.
