Adjust ACA SOT-23 5L Tape and Reel Quantity Reel Size Width 3000 7 inches 8 mm Description The FAN2500 micropower low-dropout voltage regulator utilizes CMOS technology to offer a new level of cost- effective performance in mobile handsets, laptop and notebook portable computers, and other portable devices. Features include extremely low power consump- tion, low shutdown current, low dropout voltage, excep- tional loop stability able to accommodate a wide variety of external capacitors, and a compact SOT23-5 surface- mount package. The FAN2500 offers significant improve- ments over older BiCMOS designs and is pin-compatible with many popular devices. The output is thermally pro- tected against overload. FAN2500: pin 4 – ADJ, allows the user to adjust the output voltage over a wide range using an external volt- age divider. FAN2500-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. The standard fixed output voltages available are 2.5 V, 3.0 V, and 3.3 V.

The device may not function or be opera- ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi- tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Notes: 1. Functional operation under any of these conditions is NOT implied. Performance and reliability are guaranteed only if Recommended Operating Conditions are not exceeded. 2. Applied voltage must be current limited to specified range. 3. Based upon thermally limited junction temperature: 4. Human Body Model is 4 kV minimum using Mil Std. 883E, method 3015.7. Machine Model is 400 V minimum using JEDEC method A115-A. Recommended Operating Conditions The recommended Operating Conditions table defines the conditions for actual device operation. Recommended oper- ating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recom- mend exceeding them or designing to Absolute Maximum Ratings.
