FAN2508

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. FAN2508-XX: pin 4 – BYP, to which a bypass capacitor may be connected for optimal noise performance. Output voltage is fixed, indicated by the suffix XX. FAN2509-XX: pin 4 – ERR, a flag which indicates that the output voltage has dropped below the specified minimum due to a fault condition. The standard fixed output voltages available are 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 3.0V, and 3.3V. Custom output voltage are also available: please contact your local Fairchild Sales Office for information.
