Description
This series of +3.3V voltage regulators are high current,
high accuracy, low dropout regulators and are well
suited for systems where low dropout voltages are
critical. These devices feature protection against
overtemperature, overcurrent, reverse polarity
conditions and voltage spikes. The TO-257AA (Isolated
Tab) hermetic package meets the demand for military/
defense environments.

Notes
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
26W. Power dissipation is determined by the input/output differential voltage and 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. Specifications apply over the operating temperature range.
