FAN2512, FAN2513
150 mA
CMOS LDO Regulators with Fast Start Enable
Features
Ultra Low Power Consumption Enable optimized for CDMA time phases 150 mV dropout
voltage at 150 mA 25 µA ground current at 150 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 FAN2512/13 family offer the fast power-cycle time required in CDMA handset applications. These products offer significant improvements over older Bi
CMOS designs and are pin-compatible with many popular devices. The output is thermally protected against overload. The FAN2512 and FAN2513 devices are distinguished by the assignment of pin 4: FAN2512: pin 4 – ADJ, allowing the user to adjust the output
voltage over a wide range using an external
voltage divider. FAN2512-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. FAN2513-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.
