FAN1616ASX

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

The FAN1616ASX is an adjustable positive low-dropout (LDO) linear regulator manufactured by Fairchild Semiconductor. It operates within a differential input-to-output voltage range of 1.5 V to 5.75 V and provides a maximum output current of 0.5 A. The device features a maximum dropout voltage of 1.2 V at full load, with a typical quiescent current of 4 mA. It is housed in a four-pin SOT-223 plastic package (PDSO4). Key electrical specifications include a line regulation of 0.022 %/V and a load regulation of 0.5%. The component is rated for operation across an extended temperature range from -40°C to 125°C.

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

Verify the specific manufacturer source, as Fairchild Semiconductor operations have been integrated into ON Semiconductor. Confirm that the ordering suffix corresponds to the exact pin configuration and lead-free status required for your assembly process. Ensure compatibility with the updated part numbering conventions established during the corporate integration to avoid procurement errors.

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

Select this component when a stable, adjustable voltage rail is required for logic or memory circuits with moderate current demands. The low dropout characteristic makes it suitable for battery-powered systems where input voltage may approach the desired output level. Verify that the external feedback network components meet the stability requirements specified in the official datasheet to prevent oscillation.

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

This device belongs to the FAN1616A series of LDO regulators, which are engineered specifically for USB and motherboard applications. The series includes fixed-voltage variants such as the FAN1616AS-3.3 alongside the adjustable FAN1616ASX model. These regulators share common architectural features like low quiescent current and robust transient response capabilities.
