Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for FAN2508S26X

FAN2508S26X

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

The FAN2508S26X is a fixed-output linear regulator from the FAN2508/09 family, manufactured by onsemi. It provides a regulated output voltage of 2.6V with a maximum continuous output current of 50mA. The device utilizes CMOS technology and features an extremely low dropout voltage of 50mV at full load. It includes thermal limiting protection and an enable/shutdown control pin that reduces ground current to less than 1µA when disabled. The component is housed in a compact SOT-23-5 surface-mount package.

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

Ultra-low power consumption with minimal ground current during operation
Extremely low dropout voltage for efficient battery-powered applications
Enable/Shutdown control allows user-defined power management
Onboard thermal limiting protects against overload conditions

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

Cellular phones and accessories
Personal Digital Assistants (PDAs)
Portable cameras and video recorders
Laptop, notebook, and palmtop computers

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

Verify the specific ordering suffix 'S26X' confirms the 2.6V fixed output voltage and Bypass pin configuration. Confirm the manufacturer designation as Fairchild Semiconductor or onsemi, noting historical corporate transitions. Ensure the package type matches the required SOT-23-5 footprint for PCB layout compatibility.

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

Select this component for portable designs requiring a stable 2.6V rail with minimal quiescent current draw. The wide tolerance for external capacitor ESR simplifies bill-of-materials selection. Consider the thermal resistance characteristics of the SOT-23-5 package when designing for high ambient temperatures or sustained peak loads.

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

This part belongs to the FAN2508/09 series of micropower LDO regulators designed for cost-effective performance in GSM and TDMA cellular handsets and portable computers. The FAN2508 variant specifically offers a bypass pin for noise reduction, distinguishing it from the adjustable ADJ version and the error-flag ERR version found in the FAN2509 series.

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

The datasheet notes that the FAN2508/09 family is pin-compatible with many popular older BiCMOS devices. Designers should verify pinout alignment and electrical specifications against legacy components before substitution.
