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.
