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.
