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.
