Description
The FAN2502/03 family of micropower low-dropout voltage
regulators utilize CMOS technology to offer a new level of
cost-effective performance in GSM and TDMA cellular
handsets, Laptop and Notebook portable computers, and
other portable devices. Features include extremely low
power consumption and low shutdown current, low dropout
voltage, exceptional loop stability able to accommodate a
wide variety of external capacitors, and the compact SOT23-5
surface-mount package. The FAN2502/03 family of products
offer signicant improvements over older BiCMOS designs
and are 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: pin 4 – ADJ, allowing the user to adjust the
output voltage over a wide range using an external voltage
divider.
FAN2502-XX: pin 4 – BYP, to which a bypass capacitor
may be connected for optimal noise performance. Output
voltage is xed, indicated by the sufx XX.
FAN2503-XX: pin 4 – ERR, a ag which indicates that the
output voltage has dropped below the specied minimum
due to a fault condition.
The standard xed output voltages available are 2.5V, 2.6V,
2.7V, 2.8V, 2.85V, 3.0V, and 3.3V. Custom output voltage are
also available: please contact your local Fairchild Sales
