Description 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. An enable logic control function puts the LDK120 in shutdown mode allowing a total current consumption lower than 1 µA. The device also includes a short-circuit constant current limiting and thermal protection.
Features • Input voltage from 1.9 to 5.5 V • Very low dropout voltage （100 mV typ. at 100 mA load） • Low quiescent current （max. 100 µA， 1 µA in OFF mode） • Very low noise • Output voltage tolerance： ± 2.0% @ 25 °C • 200 mA guaranteed output current • Wide range of fixed output voltages available on request： from 0.8 V to 3.5 V with 100 mV step • Adjustable version： from 0.8 V to VIN-Vdrop • Logic-controlled electronic shutdown • Compatible with ceramic capacitor COUT = 1 µF • Internal current and thermal limit • Available in SOT23-5L， SOT323-5L and DFN6 （1.2 x 1.3 mm） packages • Temperature range： -40 °C to 125 °C
