Linear voltage regulators are a type of power management circuit that is used to reduce an input voltage to a lower regulated output voltage. The STMicroelectronics L78L06ACZ-TR is an example of such a device. This 6 V linear voltage regulator has an input voltage range between 3 V and 25 V and can provide a low dropout, up to 300 mA output current and is suitable for both positive and negative voltage applications.

The L78L06ACZ-TR is a low power, low quiescent current, 3-terminal voltage regulator with integrated thermal shutdown protection, designed to regulate power supplies in a wide variety of electronic applications. The regulator is linear and is equipped with an adjustable output voltage ranging from 1.25 V up to 22 V, a guaranteed temperature drift stability of 500 mV over a temperature range of -40 °C to +125 °C and a maximum output current of 300 mA.

The working principle of the L78L06ACZ-TR is based on the linear regulation of power supply. The device compares the output voltage to an internally fixed reference voltage and adjusts the output voltage to a stable value by controlling the amount of current supplied through the pass element. The integrated thermal protection prevents the regulator from overheating by disconnecting the output from the input when the junction temperature exceeds the 150°C operating temperature. The thermal shutdown has a temperature hysteresis of approximately 20°C.

The L78L06ACZ-TR is typically used in car audio systems, home appliances, instrumentation, and industrial applications. It is also ideal for portable application products, such as mobile phones and notebooks, where low quiescent current and small physical dimensions are needed. In many cases, the L78L06ACZ-TR can eliminate the need for additional input filters, since it already has an internal compensation network.

The advantages of the L78L06ACZ-TR include low dropout voltage, high stability, fast transient response, ultra-low quiescent current, low noise, and excellent power supply rejection. The device is provided in the small SOT-89 plastic package, giving it a very low thermal resistance and improved high temperature stability.

STMicroelectronics\' L78L06ACZ-TR is a 6 V low drop-out linear voltage regulator that is designed to provide a wide input voltage range and a stable output at up to 300 mA load. It is suitable for a wide variety of electronic applications, such as mobile phones, laptops, and car audio systems. The device offers excellent line and load regulation performance, low noise, low quiescent current and can operate over a wide temperature range.
