MC78L09ACDGThe MC78L09ACDG is a 9V, 100mA positive linear voltage regulator in 8 pin SOIC package. This positive voltage regulator is an inexpensive, easy to use device suitable for a multitude of applications that require a regulated supply of up to 100mA. This regulator features internal current limiting and thermal shutdown making them remarkably rugged. It offers a substantial performance advantage over the traditional zener diode resistor combination, as output impedance and quiescent current are substantially reduced., Input voltage is 40VDC, Output voltage is 9V, No external components required, Operating temperature range from 0°C to +125°C
