DROPOUT VOLTAGE REGULATOR
OM7650SM
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

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.
