General
The FAN1581, FAN1581-1.5, and FAN1581-2.5 are three-
terminal regulators optimized for GTL+ VTT termination and
logic applications. These devices are short-circuit protected,
and offer thermal shutdown to turn off the regulator when the
junction temperature exceeds about 150°C. The FAN1581
series provides low dropout voltage and fast transient
response. Frequency compensation uses capacitors with low
ESR while still maintaining stability. This is critical in
addressing the needs of low voltage high speed microproces-
sor buses like GTL+.
Stability
The FAN1581 series requires an output capacitor as a part of
the frequency compensation. It is recommended to use a 22F
solid tantalum or a 100F aluminum electrolytic on the output
to ensure stability. The frequency compensation of these
devices optimizes the frequency response with low ESR capaci-
tors. In general, it is suggested to use capacitors with an ESR
of <1
. It is also recommended to use bypass capacitors such
as a 22F tantalum or a 100F aluminum on the adjust pin of
the FAN1581 for low ripple and fast transient response. When
these bypassing capacitors are not used at the adjust pin, smaller
values of output capacitors provide equally good results.
Protection Diodes
In normal operation, the FAN1581 series does not require any
protection diodes. For the FAN1581, internal resistors limit
internal current paths on the adjust pin. Therefore, even with
bypass capacitors on the adjust pin, no protection diode is
needed to ensure device safety under short-circuit conditions.
