Low Dropout Voltage and Ground Currents
High Current Capability
Built-In Thermal Overload Protection
Short Circuit Current Limiting
Output Voltage Tolerance Guaranteed to + 1%
Available in Multiple Hermetic Package Styles
Output Current from .75A to 3.0A
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 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.
