FAN2509 - 50 mA CMOS LDO Regulators

General Description

The FAN2508/09 family of micropower low-dropout voltage regulators utilize CMOS technology to offer a new level of cost-effective performance in GSM and TDMA cellular handsets, Laptop and Notebook portable computers, and other portable devices.

Key Features

  • Ultra Low Power Consumption 50 mV dropout voltage at 50 mA 25 µA ground current at 50 mA Enable/Shutdown Control SOT23-5 package Thermal limiting 300 mA peak current wide variety of external capacitors, and the compact SOT23-5 surface-mount package. The FAN2508/09 family of products offer significant improvements over older BiCMOS designs and are pin-compatible with many popular devices. The output is thermally protected again.

www.fairchildsemi.com FAN2508, FAN2509 50 mA CMOS LDO Regulators Features • • • • • • • Ultra Low Power Consumption 50 mV dropout voltage at 50 mA 25 µA ground current at 50 mA Enable/Shutdown Control SOT23-5 package Thermal limiting 300 mA peak current wide variety of external capacitors, and the compact SOT23-5 surface-mount package. The FAN2508/09 family of products offer significant improvements over older BiCMOS designs and are pin-compatible with many popular devices. The output is thermally protected against overload. The FAN2508 and FAN2509 devices are distinguished by the assignment of pin 4: FAN2508: pin 4 – ADJ, allowing the user to adjust the output voltage over a wide range using an external voltage divider.
