Description
The FAN2502/03 family of micropower low-dropout voltageregulators utilize CMOS technology to offer a new level ofcost-effective performance in GSM and TDMA cellularhandsets, Laptop and Notebook portable computers, andother portable devices. Features include extremely lowpower consumption and low shutdown current, low dropoutvoltage, exceptional loop stability able to accommodate a wide variety of external capacitors, and the compact SOT23-5surface-mount package. The FAN2502/03 family of productsoffer significant improvements over older BiCMOS designsand are pin-compatible with many popular devices. Theoutput is thermally protected against overload.
FAN2502 and FAN2503 versions are classified by theassignment of pin 4:
FAN2502: pin 4 - ADJ, allowing the user to adjust the output voltage over a wide range using an external voltage divider.
FAN2502-XX: pin 4 - BYP, to which a bypass capacitormay be connected for optimal noise performance. Outputvoltage is fixed, indicated by the suffix XX.
FAN2503-XX: pin 4 - /ERR, a flag which indicates that theoutput voltage has dropped below the specified minimumdue 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 arealso available: please contact your local Fairchild SalesOffice for information.
