Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

Features include extremely low power con- SOT23-5 package sumption, low shutdown current, low dropout voltage, Thermal Limiting exceptional loop stability able to accommodate a wide 300 mA Peak Current variety of external capacitors, and a compact SOT23-5 surface-mount package. The FAN2502 / 03 family offers Applications significant improvements over older BiCMOS designs and is pin-compatible with many popular devices. The Mobile Phones and Accessories output is thermally protected against overload. Portable Cameras and Video Recorders Laptop, Notebook, and Palmtop Computers 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.
