Description
The FAN2534/FAN2535 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 computers,
and other portable devices.
Proprietary design technics
ensure high ripple rejection. Other features include low
noise, short circuit current limit, thermal shutdown circuit,
low dropout voltage, fast enable required in CDMA handset
applications, exceptional loop stability to accommodate a
wide variety of external capacitors, and a compact SOT23-5
surface-mount package. These products offer significant
improvements over older Bipolar and CMOS designs and are
pin-compatible with many popular devices.
The FAN2534 and FAN2535 devices are distinguished by
the assignment of pin 4:
FAN2534:
output voltage over a wide range using an external voltage
divider.
pin 4 – ADJ, allowing the user to adjust the
FAN2534-XX:
may be connected for optimal noise performance. Output
voltage is fixed, as specified by the suffix XX.
pin 4 – BYP, to which a bypass capacitor
FAN2535-XX:
output voltage has dropped below the specified minimum
due to a fault condition.
pin 4 – ERR, a flag which indicates that the
The standard fixed output voltages available are 2.6V, 2.85V,
and 3.0V . Custom output voltages are also available: please
contact your local Fairchild Sales Office for information.
