The S-1721C2828-I6T1U is a high precision, low dropout, ultra-low quiescent current linear voltage regulator. This regulator can provide an adjustable output voltage from 0.825V to 5.5V and can handle up to 1.5A of load current. Typical applications include low-noise 3.3V and 5V supply rails and in battery powered systems. It has a dropout voltage of 500mV, high power-to-output voltage conversion efficiency, low quiescent current, low temperature coefficient, over-temperature protection, over-voltage protection, short-circuit protection and reverse current protection.

The S-1721C2828-I6T1U is designed to be used in various applications, such as audio/video equipment, mobile phones, wearables, consumer products, medical instrumentation, power management, automotive and industrial electronics. It can be used to replace less efficient switching type (or switchers) regulators in applications where noise is not an issue. This linear regulator can ensure low output noise and low input ripple noise more effectively than switching regulators.

The S-1721C2828-I6T1U linear regulator works on the basic principle of controlling the amount of current flowing through a pass transistor. It works by sensing the voltage difference between the output and the feedback inputs and then adjusting the gate voltage of the pass transistor to maintain the output voltage. This regulation is achieved by adjusting the current gain of the pass transistor circuit and thus changing the amount of voltage dropped across the device allowing the output voltage to remain stable.

The S-1721C2828-I6T1U linear regulator features a low dropout voltage, which is the amount of input voltage above the output voltage that needs to be maintained in order for the regulator to work correctly. The low dropout voltage allows the regulator to maintain regulation even when the input voltage is close to the output voltage while still allowing the highest efficiency. The efficiency is maintained by the low quiescent current, which is the amount of current required by the pass transistor during operation. It also has ultra-fast transient response and is stable with output capacitors of up to 4.7µF, further improving power supply circuitry performance.

The S-1721C2828-I6T1U is one of the latest linear voltage regulators released in the market and it is specifically designed for a wide range of applications. With its ultra-low dropout voltage, high efficiency, low quiescent current, over-temperature protection, over-voltage protection, short-circuit protection and reverse current protection, this regulator has a wide variety of applications, ranging from consumer electronics to automotive and industrial electronics.
