FAN1616AD5X

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

The FAN1616AD5X is a fixed positive linear low-dropout (LDO) voltage regulator manufactured by Fairchild Semiconductor. It provides a fixed output voltage of 5V with a maximum input voltage rating of 18V. The device supports an output current of up to 500mA and features a maximum dropout voltage of 1.2V at full load. It operates within a junction temperature range of -40°C to 125°C and is housed in a TO-252-3 (DPAK) package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Fixed 5V output regulation capability
• High current delivery up to 500mA
• Wide operating junction temperature range

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

• General purpose power management circuits
• Battery-powered equipment requiring stable 5V supply
• Embedded systems logic power rails

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

Verify the manufacturer origin, as Fairchild Semiconductor's power management division was acquired by ON Semiconductor. Ensure the component matches the specific TO-252-3 package and 5V fixed output variant. Confirm that the part number suffix 'D5X' corresponds to the correct tape-and-reel or bulk packaging configuration required for your assembly process.

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

Select this component when a stable 5V rail is required from inputs up to 18V. The 1.2V dropout voltage at 500mA necessitates an input voltage sufficiently higher than 6.2V to maintain regulation under full load. Consider thermal dissipation requirements given the DPAK package size and potential power loss during operation.

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

This part belongs to the FAN1616A series of adjustable and fixed LDO regulators. The series offers 0.5A output current capability in industry-standard packages like SOT-223 and TO-252. The FAN1616AD5X specifically denotes the fixed 5V output version in the TO-252-3 package, distinct from adjustable variants or other output voltages in the same family.

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

Compatible substitutes include other 500mA fixed 5V LDOs in TO-252 packages such as the LM2940CS-5.0 or NCP1117ST50T3G. Verify pinout compatibility and thermal performance characteristics before substitution.
