About this product

A three-terminal fixed negative voltage regulator that outputs -9 V at up to 1 A. It is used to create the negative rail in split-supply circuits, usually paired with a positive 9 V regulator. It includes thermal overload, short-circuit and safe-operating-area protection, and a heatsink is needed for currents near 1 A.

Frequently asked questions

What is the price of L7909CV -9V 1A Negative Voltage Regulator (TO-220) in Egypt?

L7909CV -9V 1A Negative Voltage Regulator (TO-220) currently costs between 9.5 and 11.4 EGP across 3 offers in Egypt.

Where can I buy L7909CV -9V 1A Negative Voltage Regulator (TO-220) in Egypt?

L7909CV -9V 1A Negative Voltage Regulator (TO-220) is available from RAM Electronics, Circuits Electronics, and UGE. Compare the offers above to find the best price.

What is the pinout of the L7909CV in TO-220?

Pin 1 is GND (common), pin 2 is the input and pin 3 is the output. The output sits at -9 V relative to GND.

What input voltage does it need?

The input must be more negative than the -9 V output by the regulator's dropout voltage, so a higher-magnitude negative supply is required. Check the datasheet for the exact dropout figure, and add the small input and output capacitors it recommends for stability.
