7905 Voltage Regulator Fixed Negative 5V Linear IC L7905CV

  • RM1.00

  • Product Code: 7905
  • Availability: In Stock

7905 is a negative 5V Voltage Regulator that restricts the voltage output to -5V and draws -5V regulated power supply. The 7905 is the most common, as its regulated -5 volt supply provides a convenient power source for most TTL components.

7905 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).
