LFXX  
Very low drop voltage regulator with inhibit function  
Datasheet  
-
production data  
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.  
Features  
Very low-dropout voltage (0.45 V)  
Very low quiescent current (typ. 50 µA in OFF  
mode, 500 µA in ON mode)  
Output current up to 500 mA  
Logic-controlled electronic shutdown  
Output voltages of 1.5; 1.8; 2.5; 3.3; 4.7; 5; 6;  
8; 8.5; 9; 12 V  
Automotive grade product: 1.8 V, 2.5 V, 3.3 V,  
5.0 V, 8.0 V, 8.5 V VOUT in DPAK and PPAK  
packages  
Internal current and thermal limit  
Only 2.2 µF for stability  
Available in ± 1% (AB) or ± 2% (C) selection at  
25 °C  
Supply voltage rejection: 80 db (typ.)  
Temperature range: from -40 to 125 °C
