Technical Data
Low Drop Regulator with Signal
IK31001
Interface Logic Circuit
DESCRIPTION
The IC is linear voltage regulator 5V with low dropout voltage typically
100mV at light loads and less then 500mV at full loads, with better then 4%
output voltage accuracy. In additional IC have logical blokes for additional
functions.
