The LT1575CN8-1.5#PBF is a member of the Linear Regulator Controllers family from the Power Management Integrated Circuits (PMIC) - Voltage Regulators. Despite being a linear regulator, the LT1575CN8-1.5#PBF can be used to source current up to 12A with only a basic bootstrap gate drive for the regulator control. This is possible due to the internal high current gate drive designed for low voltage, highly efficient power applications. While the LT1575CN8-1.5 offers a fixed output voltage of 1.5V, the adjustment voltage is fully externally adjustable, allowing it to be used in a variety of applications.

The core technology behind the LT1575CN8-1.5 is the ‘ultra low-voltage’ linear regulator controller stage. This technology allows it to operate at voltages as low as 0.2V while simultaneously driving the internal gate drive as necessary to ensure good efficiency. The low-voltage enables the circuit to be used in portable embedded applications and to provide improved solution efficiency due to its low power consumption. The circuit’s low-current features further enhances overall system efficiency by enabling the controller to source current much more quickly than modern switching regulators.

The LT1575CN8-1.5 is designed to deliver a constant output voltage of either 1.5V or 3.3V, depending on your specific requirements. This is done by controlling the current through the internal MOSFET and controlling the voltage at the output node to the desired level. The LT1575CN8-1.5 will source up to 12A of continuous current with a peak of 15A for short periods of time.

The LT1575CN8-1.5 is advantageous to power supply design because of its integrated features and the fact that it can be used in a wide variety of applications. It’s ideal for a variety of portable devices, embedded applications, and even automotive and industrial applications. The output voltage can be adjusted externally, making it very versatile in supplying both high and low voltages.

The LT1575CN8-1.5 also has several other features that make it useful for designers. It’s designed to handle input voltages between 2.6V and 18V and can start up from as low as 1.2V. Also, it has a current sensing function that accurately monitors the current through the MOSFET. This feature can detect a short-circuit or over-current condition and can shut off the power supply or hold a fixed voltage to protect the circuit. Finally, the LT1575CN8-1.5 has an adjustable soft-start feature, which can prevent inrush current when the regulator is powered on at start-up.

In short, the LT1575CN8-1.5 is an excellent choice for power supply design, due to its capability to provide excellent efficiency, its built-in features, and its wide input voltage range. Its ability to source current up to 12A and its adjustable output voltage make it ideal for a variety of applications. Additionally, its low-voltage operation and its internal high current gate drive make it reliable and cost effective.
