Functional Description
Designed utilizing CMOS process technology, the
FAN2514/15 family of products are carefully optimized for
use in compact battery-powered devices, offering a unique
combination of low power consumption, extremely low
dropout voltages, high tolerance for a variety of output
capacitors, and the ability to disable the output to less than
1μA under user control. In the circuit, a difference ampli?er
controls the current through a series-pass P-Channel
MOSFET, comparing the load voltage at the output with an
onboard low-drift bandgap reference. The series resistance
of the pass P-Channel MOSFET is approximately 1 ? ,
resulting in an unusually low dropout voltage under load
when compared to older bipolar pass-transistor designs.

Protection circuitry is provided onboard for overload condi-
tions. In conditions where the device reaches temperatures
exceeding the speci?ed maximums, an onboard circuit shuts
down the output, where it remains suspended until it has
cooled before re-enabling. The user is also free to shut down
the device using the Enable control pin at any time.
Careful design of the output regulator ampli?er assures loop
stability over a wide range of ESR values in the external
output capacitor. A wide range of values and types can be
accomodated, allowing the user to select a capacitor meeting
his space, cost, and performance requirements, and enjoy
reliable operation over temperature, load, and tolerance
variations.
