OM7648SM OM7649SM OM7650SM SURFACE MOUNT POSITIVE 0.5 VOLT, LOW DROPOUT VOLTAGE REGULATOR Isolated Hermetic Surface Mount Package Three Terminal, Fixed Voltage, 1 Amp, Low Dropout Voltage Regulator FEATURES • • • • • • • Isolated Hermetic Surface Mount Package Similar To Industry Standard LM2940 Dropout Voltage Typically 0.5 V @ IO = 1 A Output Current In Excess Of 1 A Reverse Battery Protection Internal Short Circuit Protection Available Hi-Rel Screened 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 a hermetic surface mount package and is ideally suited for Hi-Rel applications where small size and high reliability are required.
