Three Terminal, Fixed Voltage, 1 Amp

Low Dropout Voltage Regulator In

Hermetic JEDEC TO-257AA Package

FEATURES

•Similar To Industry Standard LM2940

•Approved To DESC Standardized Military Drawing

•Dropout Voltage Typically 0.5 V @ IO = 1 A

•Output Current in Excess of 1 A

•Reverse Battery Protection

•Internal Short Circuit Protection

•Isolated Hermetic Package

DESCRIPTION

These three terminal fixed voltage regulators are designed to provide 1.0A with high efficiency. It has the ability to source 1A of output current with a typical dropout voltage of .5V and a maximum of 1V over the entire temperature range. It is supplied in the hermetic TO-257 package and is ideally suited for Military applications where small size and high reliability is required.
