Texas Instruments 78SR105HC

The Texas Instruments 78SR105HC is a voltage regulator IC designed to deliver a fixed output voltage of 5V with a maximum current capacity of 1A. It comes in a TO-220 package and incorporates several protection features such as thermal shutdown and short circuit protection. The device features low dropout voltage, which means it can maintain the output voltage even when the input voltage is close to the desired output. It operates with a wide input voltage range from 8V to 40V, which makes it suitable for use in a variety of applications such as automotive, industrial, and power supplies. The typical quiescent current of the device is 5mA, which makes it efficient in battery-powered applications.

The 78SR105HC uses a feedback mechanism to maintain the output voltage at a constant value. It contains a bandgap voltage reference circuit that provides a stable reference voltage for the feedback amplifier. The output voltage is compared to this reference voltage, and any difference is amplified and used to regulate the output voltage. The device is capable of handling high input voltage spikes of up to 60V for a short duration without any damage. It is an excellent option for replacing linear regulators with a low dropout voltage, higher efficiency, and better thermal performance. The device is simple to use and requires no external compensation components, making it an ideal choice for designers who need a compact, low-cost voltage regulator with superior performance
