FAN2511

www.fairchildsemi.com FAN2510, FAN2511 100 mA CMOS LDO Regulators with Fast Start Enable Features Ultra Low Power Consumption Enable optimized for CDMA time slices 100 mV dropout voltage at 100 mA 25 µA ground current at 100 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. In addition, the FAN2510/11 family offer the fast power-cycle time required in CDMA handset applications. These products offer significant improvements over older BiCMOS designs and are pin-compatible with many popular devices. The output is thermally protected against overload. The FAN2510 and FAN2511 devices are distinguished by the assignment of pin 4: FAN2510: pin 4 – ADJ, allowing the user to adjust the output voltage over a wide range using an external voltage divider. FAN2510-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. FAN2511-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.
