FAN2502S26X

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

The FAN2502S26X is a micropower low-dropout (LDO) voltage regulator from the FAN2502/03 family, manufactured by Fairchild Semiconductor. It utilizes CMOS technology to provide a fixed positive output voltage of 2.6V with a maximum output current of 150mA. The device is housed in a compact SOT-23-5 package. Designed for cost-effective performance in portable applications, it features low quiescent current and high power supply rejection ratio (PSRR). The component is classified as obsolete and no longer in production.

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

This component is officially marked as obsolete and not in production by Fairchild Semiconductor. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Ensure that any sourced units are genuine and properly stored to prevent degradation, as end-of-life components may have varying shelf life conditions. Cross-reference with equivalent active parts if long-term supply stability is required for new designs.

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

Select this part only for maintenance or repair of existing equipment where the original design specifies the FAN2502S26X. Due to its obsolete status, it is unsuitable for new product development. Engineers should evaluate alternative active LDO regulators with similar electrical characteristics, such as 2.6V output and 150mA current capability, to ensure supply chain continuity and compliance with modern manufacturing standards.

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

The FAN2502S26X belongs to the FAN2502/03 series of micropower LDO regulators developed by Fairchild Semiconductor. This family was designed to address the power efficiency needs of early generation cellular communication devices. Fairchild Semiconductor was acquired by ON Semiconductor in September 2016, and many legacy products from this era have been discontinued. The SOT-23-5 package was standard for space-constrained portable electronics during the GSM/TDMA era.
