Description
General part information
LDK120 Series
The LDK120 low drop voltage regulator provides 200 mA of maximum current from an input supply voltage in the range of 1.9 V to 5.5 V, with a typical dropout voltage of 100 mV.
It is stabilized with a ceramic capacitor on the output.
The very low drop voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications.
