The UA78M05CDCYR is a Positive-Voltage Regulator. This line of integrated circuit voltage regulators with fixed voltage is made for a variety of uses. Applications include single-point regulation's distribution issues and noise removal using on-card control. These regulators each have an output current capacity of 500 mA. These regulators are essentially impervious to overload because of their inbuilt current-limiting and thermal-shutdown features. These components can be utilized as precision regulators' power-pass components as well as fixed-voltage regulators, obtaining adjustable output voltages and currents by combining them with external components.
