Three Terminal, Fixed Voltage, 1 Amp Low Dropout Voltage Regulator In Hermetic JEDEC TO-257AA Package

Similar To Industry Standard LM2990 Dropout Voltage Typically 1 A Output Current in Excess 1 A Low Quiescent Current Internal Short Circuit Protection Isolated Hermetic Package

These three terminal fixed negative 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.6V 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.
