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.

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
Logic-controlled electronic shutdown
Compatible with ceramic capacitor
COUT = 1 µF
Internal current and thermal limit
Available in SOT23-5L, SOT323-5L, SOT-89
and DFN6-1.2x1.3 packages
Temperature range: -40 °C to 125 °C
October 2016
The very low drop voltage, low quiescent current
and low noise make it suitable for batterypowered 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.
