The MC7915ACT is a linear voltage regulator designed to provide precision voltage levels for electronic devices and can be used for a variety of application fields. The MC7915ACT is a three-terminal device with a wide input voltage range, low dropout voltage, fixed output voltage, and a low power quiescent current. It is a low noise and low ripple voltage regulator which can provide a constant stable supply voltage for electronic circuits.

Design and Working Principle

The MC7915ACT is a 3−terminal negative voltage regulator. It has an input voltage range between 4.5 V and 40V with a 6V Fixed Output voltage with a minimum load current of 1mA. The maximum output current drawn by the device is 1A and it has an operating junction temperature range of −55˚C to 150˚C.

The MC7915ACT has an internal error amplifier which provides feedback to regulate the output voltage across its collector and emitter terminals. The output voltage is maintained at the preset level by adjusting the base current of the internal PNP transistor to maintain the output voltage. The output voltage is proportional to the voltage difference between the collector and the emitter, which is maintained by the error amplifier.

The MC7915ACT is also equipped with overtemperature and overload protection. When the temperature exceeds the rated value (150˚C) or if an excessive current is drawn from the device, the output voltage will shut off and the device will enter a protection state. This prevents the device or the system from being damaged due to excessive temperature or current overload.

Applications

The MC7915ACT is designed to provide precision voltage levels for a wide range of applications. It can be used as a fixed voltage regulator for battery-powered machines, alarm systems, and other electronic equipment. It is also suitable for use in automotive and industrial applications where a reliable and precise power supply is necessary. The MC7915ACT can also be used as a low-power voltage regulator for fixed and adjustable voltage references, providing a steady output voltage even in the presence of line transients and noise. Additionally, it can be used in LED lighting and LCD monitors and displays, providing a stable and reliable power source for these devices.
