NCP508MT18TBG is a linear voltage regulator integrated circuit created by ON Semiconductor. It is specifically designed for low-noise, high-performance applications where output current demand is low. With its low standby current draw, this regulator is ideal for portable or battery-powered applications. This linear voltage regulator is a cost-effective solution that provides excellent electrical performance and low power consumption.

NCP508MT18TBG’s main application field is portable equipment, such as cellular phones, PDAs, digital cameras, and other portable electronic devices. It provides excellent load regulation for battery-powered equipment. This device can also be used in other applications, such as automotive, medical, and video equipment, where low output noise and high ripple rejection are required.

The working principle of the NCP508MT18TBG is based on a shunt regulator topology. This circuit consists of two transistors to form a voltage regulator. The two transistors are configured in a shunt regulator topology in order to achieve high ripple rejection and low output noise. This topology ensures that the input voltage is maintained at a constant level by controlling the current flow. When the output voltage deviates from the desired level, the current is regulated in order to maintain the output voltage constant.

NCP508MT18TBG is a three-terminal adjustable linear voltage regulator with floating outputs. It can be used to provide an adjustable output voltage from 0.8 V to 18 V. It has excellent line and load regulation of 0.03% and 0.06% respectively. It also features over-voltage protection that limits voltage output to 18 V and under-voltage protection that limits voltage output to 0.8 V. This device also features extremely low thermal resistance and high power supply rejection ratio of greater than 60 dB at 20 kHz.

The NCP508MT18TBG has a maximum operating temperature range of -40°C to 125°C, and a thermal protection circuit that shuts the device off if the junction temperature exceeds 150°C. This device has a wide input voltage range of 2.5 V to 11 V and a maximum output current of 500 mA. It is available in a small surface-mount package and is RoHS compliant.

In conclusion, NCP508MT18TBG is a low-noise, high-performance linear voltage regulator with extremely low thermal resistance and high power supply rejection ratio. It is designed for low-output current applications, and is ideal for portable electronic devices such as cellular phones, PDAs, digital cameras, and other battery-powered equipment. With its wide input voltage range, excellent line and load regulation, over-voltage and under-voltage protection, and RoHS compliance, NCP508MT18TBG is a cost-effective solution for any application requiring an adjustable linear voltage regulator.
