DESCRIPTION
This series of +3.3 Voltage Regulators are high current, high accuracy, low dropout regulators
protection against overcurrent faults, reversed input polarity, reversed lead insertion, over tem-
perature operation and positive and negative transient voltage spikes. They are available in a
number of hermetic package styles where critical environmental systems demand high per-
formance.
