Description
The FAN2502 / 03 family of micropower low-dropout volt-
age regulators utilize CMOS technology to offer a new
level of cost-effective performance in mobile handsets,
laptop and notebook portable computers, and other por-
table devices. Features include extremely low power con-
sumption, low shutdown current, low dropout voltage,
exceptional loop stability able to accommodate a wide
variety of external capacitors, and a compact SOT23-5
surface-mount package. The FAN2502 / 03 family offers
significant improvements over older BiCMOS designs
and is pin-compatible 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.

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 Recommended Operating Conditions are not exceeded.
2. Applied voltage must be current limited to specified range.
3. Based upon thermally limited junction temperature:
PD = T----J---(-m---Θ-a---x-J--)A---–----T----A--
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.
