The MC7915BD2TG is an adjustable, very-low-drop, 3-terminal linear voltage regulator providing excellent protection and regulation against over-voltage, under-voltage, and short circuit conditions. It has a wide input voltage range of 4.75~36V and delivers a steady output voltage of up to 36V. This makes the MC7915BD2TG suitable for applications requiring higher primary power supplies and having tightly regulated output voltages.

The MC7915BD2TG is typically used in power supply, voltage regulator, and on board regulator for industrial, medical, and consumer electronics applications. It is designed for wide range adjustable output voltage and low noise operation, allowing it to power supplies with a high degree of accuracy. The regulator features over-voltage protection, under-voltage lockout, overload protection, as well as active-low power-good indicator.

The MC7915BD2TG is implemented with a three terminal linear voltage regulator which includes an N-channel power MOSFET in its output stage. The series pass FET helps provide a low dropout voltage, eliminating the need for a large number of output capacitors and thus helping to lower input and output ripple. Additionally, the integrated MOSFET helps protect against output current surges.

To start, the MC7915BD2TG requires two input nodes: one called the reference voltage input (Vref), and the other known as the ground node. Output voltage is adjustable by one external network. The current operation of the regulator is determined by an internal current source. When the voltage at the regulator input exceeds the reference voltage, the regulator will begin to regulate its output voltage. The output voltage will drop until VSense becomes equal to the reference voltage.

The MC7915BD2TG from STMicroelectronics is designed with a wide range of features that provide unparalleled levels of protection for consumer electronics and industrial applications. The device offers accurate voltage regulation and fast response time to transient load conditions. It also features low noise operation, overload protection, under-voltage lockout, and over-voltage protection. Add to that active-low power-good indicator, and you have a device that is ideal for many applications.

Overall, the MC7915BD2TG is a prime choice for implementing a low voltage linear voltage regulator in consumer electronics, medical, and industrial applications with an adjustable output voltage of up to 36V. It is capable of providing protection against over-voltage conditions and protecting against overcurrents. Its active low power-good indicator ensures reliable voltage monitoring and it is backed by a lifetime warranty.
