The FAN2512/13 family of micropower low-dropout voltage
regulators utilize CMOS technology to offer a new level of
cost-effective performance in GSM, TDMA, and CDMA 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. In addition, the FAN2512/13 family offer the fast power-cycle time required in CDMA handset applications. These products
offer significant improvements over older BiCMOS designs
and are pin-compatible with many popular devices. The
output is thermally protected against overload.
FAN2512 and FAN2513 versions are distinguished by the
assignment of pin 4:
FAN2512: pin 4 - ADJ, allowing the user to adjust the output voltage over a wide range using an external voltage divider.
FAN2512-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.
FAN2513-XX: pin 4 - /ERR, a flag which indicates that the
output voltage has dropped below the specified minimum
due to a fault condition.
The standard fixed 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
Office for information.
