www.fairchildsemi.com FAN2518, FAN2519 50 mA CMOS LDO Regulators with Fast Start Enable Features Ultra Low Power Consumption Enable optimized for CDMA time phases 50 mV dropout voltage at 50 mA 25 A 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. In addition, the FAN2518/19 family offer the fast power-cycle time required in CDMA handset applications. These products offer signicant improvements over older BiCMOS designs and are pin-compatible with many popular devices. The output is thermally protected against overload. The FAN2518 and FAN2519 devices are distinguished by the assignment of pin 4: FAN2518: pin 4 – ADJ, allowing the user to adjust the output voltage over a wide range using an external voltage divider. FAN2518-XX: pin 4 – BYP, to which a bypass capacitor may be connected for optimal noise performance. Output voltage is xed, indicated by the sufx XX. FAN2519-XX: pin 4 – ERR, a ag which indicates that the output voltage has dropped below the specied minimum due to a fault condition. The standard xed 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 Ofce for information.
