DESCRIPTION
The TK11900 is a low dropout voltage regulator with external
voltage adjustment. The output can be set between 1.5 V
and 15 V by an external pair of resistors in a divider
configuration. The device has a bypass pin for an external
capacitor to reduce output noise to a typical 50 µV(rms). In
addition, a control pin is provided that is active low (a low
level turns on the output). In the “off” mode (control pin high)
the device draws only 65 µA of quiescent current.
The TK11900 is available in a miniature SOT-23L surface
mount package.
