TPS71711DCKTG4

TPS71711DCKTG4 is an adjustable low-dropout linear regulator from Texas Instruments. It is ideal for small to medium power applications. It is designed to provide up to 250mA of current at up to +4V. This regulator can also provide up to 240mA of continuous current with a 1V dropout voltage. This makes it well suited for low-power portable battery powered applications.

The TPS71711DCKTG4 regulator can be configured with an adjustable output voltage range of 1.6V to 5.5V. It also features an adjustable soft-start time of up to 1kHz,over-voltage and under-voltage protection, and thermal shutdown. Its low cost makes it popular for applications such as medical, industrial, and consumer electronics.

Application Fields: The TPS71711DCKTG4 is ideal for powering small battery-powered applications in medical, industrial, and consumer electronics. It is well suited for portable low-power and low-dropout voltage applications such as cellular phones, tablets, IoT devices, and data acquisition systems, and is especially useful for applications in transportation and automotive electronics.

Working Principle: The TPS71711DCKTG4 is an adjustable low drop-out linear regulator. It works on the principle of Derating Voltage Regulation. The regulator controls the amount of voltage drop across the input and output of a circuit by adjusting the current correspondingly. The voltage drop across the input and output is equal to the product of the current passing through the circuit and the resistance. Thus, the regulator can maintain the voltage drop across the input and output of the circuit by adjusting the current, resulting in a constant output voltage.

The TPS71711DCKTG4 regulator has an input operating voltage range of 4.6V to 17V and can provide an adjustable output voltage. It also has over-voltage and under-voltage protection and thermal shutdown. The adjustable soft-start time of up to 1kHz allows the regulator to manage the current draw on startup and minimize the risk of brownouts or surges. Its low-cost makes it an ideal choice for low-power portable battery powered applications.

The high efficiency of the TPS71711DCKTG4 allows it to reduce power losses and has a maximum efficiency of over 90% in some application scenarios. It is available in an ultra-compact 2x2mm2 plastic power package and is lead-free and RoHS compliant.
