It is widely used in DC/DC voltage converters, power supply unit, Uninterruptible Power Supply (UPS), Security systems, solid state lighting, automotive electronics, and a wide selection of other electrical circuitry solutions.The LX8117A-00CST Linear Voltage Regulator offers an excellent protection solution for many control and power circuitry applications. It ensures a stable output voltage even when exposed to fluctuating input pressures, so that any system it is used in operates smoothly at safe power levels. It is important to note that the output current of LX8117A-00CST must not exceed the absolute maximum ratings specified.

Working Principle of LX8117A-00CST

The LX8117A-00CST Linear Voltage Regulator works by measuring the input voltage, modifying it with a feedback mechanism and providing a steady output voltage at that ratio.The output voltage is determined by the internal voltage scaling network, which comprises of a low value resistor and a capacitor. The combination of this network is referred as an error amplifier. The error amplifier senses a suitable voltage reference that sets the desired output voltage from a suitable reference source.When the input voltage is higher than the reference voltage, the error amplifier adjust the scaling network until the reference voltage becomes equal to the input voltage. Thus, the output voltage becomes regulated, although the input voltage may also vary.

Conclusion

LX8117A-00CST is a Linear Voltage Regulator that is developed by PT Electronics Inc. It is designed to offer a cost effective voltage regulating solution for a wide range of low to medium power electronics applications in many consumer and industrial applications. It works by adjusting the scaling network until the reference voltage is equal to the input voltage, thus providing a regulated output voltage. LX8117A-00CST is highly recommended for many controllers, UARTs, and popular Power Management Systems.
