CS8321YT3

The CS8321YT3 is a linear voltage regulator IC manufactured by CS-Chi Semiconductor. It is a three-terminal voltage regulator IC that provides excellent line and load regulation and minimal noise over a wide output voltage range.

The CS8321YT3 is a low dropout linear voltage regulator with a high power supply rejection ratio. It operates over a wide input voltage range of 3.3V to 32V and has a fixed-voltage output accuracy of ±1.0%. It also features an operating temperature range of -40℃ to +125℃ and has a power dissipation of 150 mW.

The CS8321YT3 is designed for use in applications such as personal computers, industrial equipment, cellular phones, and hand-held devices. It is ideal for powering microprocessors, FPGAs, RF transceivers and other sensitive electronics as it can accurately maintain its output voltage over a range of input voltages and temperatures.

The CS8321YT3 works on the same principle as other linear voltage regulators. It is designed to transform a higher input voltage level to a predetermined lower output voltage level. This is done by means of a voltage regulator, which consists of a series of transistors, resistors, and a voltage sense switch. When the input voltage exceeds the desired output voltage level, the voltage sense switch opens, allowing current to flow into the regulator until the output voltage is equal to the desired output voltage.

The CS8321YT3 also features built-in protection circuits to protect against current overshoot, thermal overload, and short circuit. The protection circuitry monitors the input and output voltages and will shut down the device in case of an over or under voltage situation. It also offers a soft start feature, which can eliminate large inrush currents and allow the regulator to start up at a slower rate.

The CS8321YT3 is housed in a TDFN-8H package, which measures 1.2 x 1.2 mm and has a height of 0.45 mm. This makes it ideal for use in portable and compact applications. The device also meets the requirements of the RoHS directive, making it suitable for use in industrial applications.

The CS8321YT3 is a versatile and reliable linear voltage regulator IC that is ideal for any end application requiring a low dropout, high power supply rejection, and an accurate and stable output voltage. Its protection mechanisms, small size, and low power consumption makes it the ideal choice for mobile and other applications requiring accurate voltage regulation.
