This is the new generation of the
PT78HT200 Series wide input range
3 terminal regulators. These ISRs have
a maximum output current of 2.0 Amps.
The output voltage is laser trimmed
for high accuracy.
These 78 series regulators have excel-
lent line and load regulation with internal
short-circuit and over-temperature protec-
tion, and are offered in a variety of standard
output voltages. These ISRs are very flex-
ible and may be used in a wide variety of
applications.
