The LM78L12ACZ/LFT3 is a three-terminal, positive voltage regulator that is a member of the LM78Lxx family of linear integrated circuit regulators. It offers improved line and load regulation and utilizes an internal architecture designed specifically to reduce power dissipation making it an effective solution for oversized board layouts. This voltage regulator can also be used in junction connection regulating applications.

The LM78L12ACZ/LFT3 has a wide input voltage range of 1.5V to 18V, and a regulated output voltage of 12V ± 4%. The device is rated to operate over the temperature range of –40°C to 125°C, with the maximum power dissipation of 0.5W at 25°C ambient temperature. It is available in three different package types including TO-92, SOT-223 and SOT-89. The LM78L12ACZ/LFT3 features an ultra-low dropout voltage, making it an ideal solution for low-current applications, such as LED and low power logic systems.

The LM78L12ACZ/LFT3 is commonly used in applications, such as automotive and process control systems, telecom and computer peripherals, audio amplifiers and other consumer electronics. It can also be used in junction connection regulating applications, such as those where the regulator is located in the same circuit as the load, ensuring improved load regulation.

The LM78L12ACZ/LFT3 has a very low quiescent current, making it an ideal solution for battery-powered systems. The minimum output current of this device is 300mA and the maximum output current is 500mA. It also supports over-voltage protection and over-current protection. This device is designed to be very tolerant of input line transients, making it suitable for use in virtually any environment.

The LM78L12ACZ/LFT3 is a monolithic positive linear voltage regulator from the LM78Lxx family. It is designed to provide adjustable output voltage from 1.2V to 18V. The input voltage to the device must be between 1.25V and 18V. The output voltage is selected by connecting an external resistor divider network to the two adjustable terminals at the input of the device. The regulator uses an internal series pass transistor, which regulates the output voltage to be equal to the voltage applied to the adjustable terminals.

The LM78L12ACZ/LFT3 features an internal compensation circuit that prevents output voltage from oscillating, even with varying load conditions. It also offers improved line regulation and load regulation. The device requires a minimum load current of 10mA and a maximum load current of 500mA. It has a minimum dropout voltage at full load of 1V and a maximum output ripple voltage of 50mVpp.

The LM78L12ACZ/LFT3 also features short-circuit protection, with an internal load shorting switch that acts to disconnect the load from the input when the output reaches a set level. This feature prevents overloading of the regulator, and also provides thermal protection in the event of a fault condition. This device is also designed to be reverse-polarity protected, with an input protection diode which prevents damage caused by accidental reverse polarity connections.

The LM78L12ACZ/LFT3 is designed to deliver maximum power saving and stability when used in low-current applications. The low power dissipation results in reduced heat generation, allowing the device to operate over an extended temperature range. With an improved line and load regulation, this device offers an efficient and reliable solution for a wide range of applications.
