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.
