The TPS77401DGK is a low-dropout (LDO) liner voltage regulator that offers current up to 400mA with low quiescent current (200uA typical). The device is ideal for applications such as power-supply sequencing, sequenced power management, and power-distribution networks in 1.8V to 3.3V systems.

The TPS77401DGK is a single-series, adjustable, low-cost, ultra-low-power linear voltage regulator specifically designed to regulate low voltage levels. It features an internal 100mA output current limit, high-temperature and dual-input operation, and an ultra-low dropout voltage of 250mV which helps to reduce input-to-output voltage difference. In addition, the device requires very low quiescent current and delivers fast start-up and turn-on delay time.

The TPS77401DGK can be used to directly regulate 5V or 3.3V to 1.8V, 2.8V or 3V in a variety of systems or devices requiring a high performance but reliable regulator solution. The device is optimized for buck-mode operation, but can also be used for applications such as power distribution, programmable regulators, and low-dropout voltage converters. It can also be used in harnessing large systems with multiple power stages, power sequencing, and power allocation networks.

The device has an adjustable series-operated architecture with a reference voltage of 1.2V and an adjustable current limit of up to 400 mA. This architecture is highly efficient and allows for wide dynamic input and output voltage range. A unique feature of the TPS77401DGK is that it has a shutdown pin that can be used to minimize power consumption by enabling or disabling the device. This pin can be used to power the system down when not in use.

The TPS77401DGK is manufactured using high-quality components and provides excellent performance in terms of accuracy, low output noise and low dropout voltage (DIFF). The device shows good line regulation, load regulation and temperature stability. In addition, it provides a fast transient response and low quiescent current.

The working principle of the TPS77401DGK is based on a voltage reference which creates a precise reference voltage. This reference voltage is applied to the gate of a series pass transistor connected to the regulator\'s input and output nodes. The pass transistor\'s gate is biased at the reference voltage and provides a highly accurate output regulation over a wide range of input and output voltages. The output current is limited by an internal resistor. The quiescent current of the device is set by an internal resistance, typically 190 uA.

In summary, the TPS77401DGK is a LM charging/discharging controller, low dropout linear voltage regulator ideal for powering low-voltage systems such as microcontrollers, FPGA and ASICs. It is cost effective, reliable, efficient and offers high accuracy, low noise and a fast transient response. It is specifically designed for applications requiring low input-to-output voltage difference and very low quiescent current. This makes it suitable for harnessing large systems with multiple power stages, power sequencing, and power allocation networks.
