L4931ABxx  
L4931Cxx  
Very low drop voltage regulators with inhibit  
Features  
■ Very low dropout voltage (0.4 V)  
■ Very low quiescent current  
■ (Typ. 50 µA in off mode, 600 µA in on mode)  
■ Output current up to 250 mA  
■ Logic-controlled electronic shutdown  
■ Output voltages of 2.7; 3.3; 3.5; 5; 8; 12 V  
■ Automotive Grade product: 2.7 V, 3.3 V, 3.5 V  
TO-92  
TO-220

■ Internal current and thermal limit  
■ Only 2.2 µF for stability  
PPAK  
SO-8  
DPAK  
■ Available in 1 ꢀ (Aꢁ) or 2 ꢀ (C) selection at  
25 °C  
■ Supply voltage rejection: 70 dꢁ typ. for 5 V  
This means that when the device is used as a  
local regulator, it is possible to put a part of the  
board in standby, decreasing the total power  
consumption. It requires only a 2.2 µF capacitor  
for stability allowing space and cost saving.  
version  
■ Temperature range: -40 to 125 °C  
Description  
The L4931 is available as Automotive Grade in  
SO-8 package only, for the options of output  
voltages whose commercial Part Numbers are  
shown in the Table 19 on page 34 (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, SꢁL are  
performed.  
The L4931Aꢁxx L4931Cxx are very Low Drop  
regulators available in TO-220, SO-8, DPAK,  
PPAK and TO-92 packages and in a wide range of  
output voltages.  
The very low drop voltage (0.4 V) and the very low  
quiescent current make them particularly suitable  
for low noise, low power applications and  
specially in battery powered systems.  
A TTL compatible shutdown logic control function  
is available in PPAK and SO-8 packages.
