It has an adjustable output voltage range of 1.2V to 2.7V and features power good, output overcurrent protection and thermal shutdown protection. The device is offered in the mini-BGA package.

Application Field

The S-1131B27PD-N4MTFG is capable of providing a regulated output voltage with a high level of accuracy and line regulation. It can be used in a variety of power management applications such as battery charging and power supply voltage stabilization.

The S-1131B27PD-N4MTFG is ideal for applications that require a precise output voltage provided by an integrated circuit. These applications include automotive and industrial systems, medical equipment, telecommunication systems and consumer electronics.

Working Principle

The S-1131B27PD-N4MTFG is a linear voltage regulator based on a P-channel MOSFET (PMOS) integrated circuit. It operates by using the voltage input to create a negative voltage which is then applied to the base of the PMOS transistor to turn it off. The output voltage is then regulated by adjusting the current that is flowing through the transistor.

The S-1131B27PD-N4MTFG features a two-stage power supply system. The first stage is a low-loss preregulated voltage that is provided by a built-in P-channel MOSFET. The second stage is the main regulator, a low drop-out regulator. This main regulator is responsible for providing a precisely regulated output voltage.

The device also features power good and overcurrent protection, as well as thermal shutdown. Power good indicates when the device has been turned on and is operating within its specified range. Overcurrent protection prevents the device from drawing excessive current from the input voltage source, while thermal shutdown shuts down the device when the temperature exceeds a certain limit.

Conclusion

The S-1131B27PD-N4MTFG is an integrated circuit designed to provide a regulated output voltage with a high level of accuracy and line regulation. It can be used in a variety of power management applications such as battery charging and power supply voltage stabilization. The device features power good, output overcurrent protection, and thermal shutdown protection and can be used in automotive and industrial systems, medical equipment, telecommunication systems, and consumer electronics.
