100mA negative LDO in SOT-23 package.
This CMOS device regulates a negative supply down to a
fixed voltage level at 2% accuracy.
It offers exceptional LDO performance of 120mV dropout at
50mA current levels.
The device also comes in a 3-lead SOT-89 package, for a
number of voltage and current offerings.
