LDK220M33R Product Details

The LDK220M33R 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 LDK220M33R 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.


  • Input voltage from 2.5 to 13.2 V
  • Very low-dropout voltage (100 mV typ. @ 100 mA load)
  • Low quiescent current (typ. 55 μA, 1 μA in off mode)
  • Low noise
  • Output voltage tolerance: ± 2.0% @ 25 °C
  • 200 mA guaranteed output current
  • Wide range of output voltages available on request: fixed from 1.2 V to 12 V with 100 mV step and adjustable
