FAN2502 / FAN2503 - 150 m A CMOS LDO Regulator May 2013 FAN2502 / FAN2503 150 m A CMOS LDO Regulator Features - Ultra-Low Power Consumption - 150 m V Dropout Voltage at 150 m A - 25 μA Ground Current at 150 m A - Enable / Shutdown Control - SOT23-5 package - Thermal Limiting - 300 m A Peak Current Applications - Mobile Phones and Accessories - Portable Cameras and Video Recorders - Laptop, Notebook, and Palmtop puters Description The FAN2502 / 03 family of micropower low-dropout voltage regulators utilize CMOS technology to offer a new level of cost-effective performance in mobile handsets, laptop and notebook portable puters, and other portable devices. Features include extremely low power consumption, low shutdown current, low dropout voltage, exceptional loop stability able to acmodate a wide variety of external capacitors, and a pact SOT23-5 surface-mount package. The FAN2502 / 03 family offers significant improvements over older Bi CMOS designs and is pin-patible with many popular devices. The output is thermally protected against overload. The FAN2502 and FAN2503 devices are distinguished by the assignment of pin 4: FAN2502-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. FAN2503-XX: pin 4 - ERR, a flag that indicates that the output voltage has dropped below the specified minimum due to a fault condition. The standard fixed output voltages available are 2.5 V and 3.3 V. Ordering Information Part Number FAN2502S25X FAN2503S33X VOUT 2.5 3.3 Pin 4...
