Description
The FAN2504 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 FAN2504 offers significant improvements over older
BiCMOS designs is are pin-compatible with many popu-
lar devices. The output is thermally protected against
overload.
A bypass capacitor may be connected to pin 4 for optimal
noise performance.
Applications
• Mobile Phones and Accessories
• Portable Cameras and Video Recorders
• Laptop, Notebook, and Palmtop Computers

Absolute Maximum Ratings
(1)
Stresses exceeding the absolute maximum ratings may damage the device. 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 Recommend Operating Conditions are not exceeded.
2. Applied voltage must be current limited to specified range.

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.
