LDK220  
200 mA low quiescent current and low noise LDO  
Datasheet - production data  
Applications  
Battery-powered equipment  
TV  
Set-top box  
PC and laptop  
Industrial  
Description  
The LDK220 is a low drop voltage regulator,  
which provides a maximum output current of  
200 mA from an input voltage in the range of  
2.5 V to 13.2 V, with a typical dropout voltage of  
100 mV.  
A ceramic capacitor stabilizes it on the output.  
Features  
The very low drop voltage, low quiescent current  
and low noise make it suitable for battery-  
powered applications.  
Input voltage from 2.5 to 13.2 V  
Very low-dropout voltage (100 mV typ. @  
100 mA load)  
The enable logic control function puts the  
LDK220 in shutdown mode allowing a total  
current consumption lower than 1 µA.  
Low quiescent current (typ. 55 µA, 1 µA in  
off mode)  
Low noise  
Output voltage tolerance: ± 2.0% @ 25 °C  
200 mA guaranteed output current  
Wide range of output voltages available on  
request: fixed from 1.2 V to 12 V with  
100 mV step and adjustable  
The device also includes a short-circuit constant  
current limiting and thermal protection.  
Logic-controlled electronic shutdown  
Compatible with ceramic capacitor  
COUT = 1 µF  
Internal current and thermal limit  
Available in SOT23-5L, SOT323-5L, SOT-89  
and DFN6-1.2x1.3 packages  
Temperature range: -40 °C to 125 °C
