Description
The LFXX is a very low drop regulator available
in TO-220, TO-220FP, DPAK and PPAK
packages and in a wide range of output voltages.
The low drop voltage (0.45 V) and low quiescent
current make it particularly suitable for low-noise,
low-power applications and especially in battery-
powered systems. In the 5 pin configuration
(PPAK) a shutdown logic control function is
available (pin 2, TTL compatible). This means
that when the device is used as a local regulator,
a part of the board can be put in standby,
decreasing the total power consumption. In the
three terminal configuration, the device has the
same electrical performance, but it is fixed in ON
state. It requires a capacitor of only 2.2 µF for
stability, saving board space and costs. The
LFXX is available as automotive grade in DPAK
and PPAK packages, for the options of output
voltages whose commercial part numbers are
shown in the order codes. These devices are
qualified according to the specification
AEC-Q100 of the automotive market, in the
temperature range -40 °C to 125 °C, and the
statistical tests PAT, SYL, SBL are performed.
