Product overview
Description
The LDK130 low drop voltage regulator provides 300 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 LDK130 in shutdown mode allowing a total current consumption lower than 1 μA.
The device also includes short-circuit constant current limiting and thermal protection.
-
