DESCRIPTION
TO-220B
As the UTC linear integrated LDO, the UTC 78RXX shows a
high current, high accuracy, and specially low-dropout voltage. The
features are: maximum 500mV dropout voltage, very low ground
current. Cause the series have been designed for high current
loads, so they are also used in lower current, extremely low
dropout-critical systems (in which their tiny dropout voltage and
ground current values are important attributes).
