DESCRIPTION
This series of +3.3 Voltage Regulators are high current, high accuracy, low dropout regulators
and well suited for systems where extremely low dropout voltages is critical. They feature full
protection against overcurrent faults, reversed input polarity, reversed lead insertion, over temperature operation and positive and negative transient voltage spikes. They are available in a
number of hermetic package styles where critical environmental systems demand high performance.

Notes:
3.3
1. Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 15W
for the OM7670 series and 30 watts for the OM7671 series (See Table 1). Power dissipation is determined by the
input/output differential voltage and the output current. Guaranteed maximum power dissipation will not be available over
the full input/output voltage range.
2. Guaranteed by design, characterization or correlation to other tested parameters.
3. The • denotes the specifications which apply over the full operating temperature range.
