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.
