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.
