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.
The very low drop voltage, low quiescent current
and low noise make it suitable for battery-
powered applications.
The enable logic control function puts the
LDK220 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.
