KFxxB  
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, 500 µA in ON Mode)  
Output current up to 500 mA  
Logic-controlled electronic shutdown  
Output voltages of 1.5; 2.5; 3; 3.3; 4; 5; 5.2; 6; 8  
Internal current and thermal limit  
Only 2.2 µF for stability  
DPAK  
SO-8  
Available in 2 % accuracy at 25 °C  
Supply voltage rejection: 70 db (typ.)  
Temperature range: -40 to 125 °C  
Description  
The KFxx series are very low drop regulators  
available in SO-8 package 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 shutdown logic control function is available (pin  
5, TTL compatible). 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.
