DescriptionThe FAN2518/19 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 FAN2518/19 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.
The FAN2518 and FAN2519 devices are distinguished by
the assignment of pin 4:
FAN2518: pin 4 – ADJ, allowing the user to adjust the
output voltage over a wide range using an external voltage
divider.
FAN2518-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.
FAN2519-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.
