UA7805C Positive Voltage Regulator 005 2.1MM Back 3-Pins DC Jack/Socket just plug it into aThis line of integrated circuit voltage regulators with fixed voltage is made for various uses. Among these uses is on card regulation, which reduces noise and the distribution issues brought on by single point regulation. These regulators each have an output current capacity of 1. 5 A. These regulators are impervious to overload because of their inbuilt current limiting and thermal shutdown features. These devices can be utilised as adjustable output
