L7912CV negative Voltage Regulator (-12V -1A) taywan

L7912CV negative Voltage Regulator (-12V -1A) taywan is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. Negative Voltage Regulator 12V-7912
7912 is a negative 12V Voltage Regulator that restricts the voltage output to -12V and draws -12V regulated power supply. The 7912 is the most common, as its regulated -12 volt supply provides a convenient power source for most TTL components.

7912 is a series of 79XX negative voltage regulators (as known as L79xx , LM79xx , MC79xx …), the xx is replaced with two digits, indicating the output voltage (for example, the 7905 has a negative 5-volts output, while the 7912 produces negative 12-volts).
