TPS76901HDBVT is an adjustable 3-A high-accuracy low-dropout linear regulator. It offers three adjustable output voltage ranges from 0.8 V up to 6 V, with an output accuracy of up to 0.5%. This regulator also provides high PSRR (power supply rejection ratio), which ensures the stability of the circuit even when the input power source interrupts.

The line and load regulation of TPS76901HDBVT is excellent with a maximum 0.2% line and 0.1%% load tolerant voltage variation. Its high switching frequency also helps to reduce the output capacitor size. This makes it an ideal choice for portable electronics (e.g. mobile phones, tablets, laptop etc).

TPS76901HDBVT is also very energy efficient with a typical quiescent current of only 25 µA, making it suitable for battery driven applications. The built-in over-temperature and over-current protection ensures reliable operation in circuits with limited heatsinking and inductors.

Powering up the TPS76901HDBVT is easy with a high accuracy enable pin, which supports positive and negative logic signals. While providing excellent dropout accuracy and power savings, the regulator also offers a fast transient response time of less than 1 µs.

TPS76901HDBVT is ideal for a wide range of applications, including small digital systems, computer peripherals, broadcasting and audio equipment, and automotive audio. With its wide range of adjustable output voltage, low dropout, high output current, and low quiescent current, it provides reliable power conversion and protection.

The working principle of TPS76901HDBVT is a two-stage power conversion process that is commonly referred to as a low-dropout (LDO) regulator. In the first stage, an error amplifier monitors the output voltage and compares it with a reference voltage. If the output voltage is lower than the reference voltage, the error amplifier increases the amount of current being supplied to the output, which raises the output voltage.

In the second stage, a pass element controls the flow of current through the system, ensuring that the output voltage is maintained or supplied as required. The pass element also acts as a switch, allowing current to flow through the regulator only when it is required and not otherwise.

The combination of these two stages allows the TPS76901HDBVT to provide a low-dropout, high-accuracy output voltage, while maintaining an extremely low quiescent current. This low-dropout regulator also features a built-in MOSFET that allows the designer to include pre- and post-load bias sequencing.

In conclusion, TPS76901HDBVT is a 3-A adjustable low-drop linear regulator with excellent accuracy and high PSRR. Its adjustable output voltage range from 0.8 V up to 6 V makes it suitable for a wide range of applications. The built-in over-temperature and over-current protection ensures reliable operation in circuits with limited inductors and heatsinking. With its fast transient response time and power savings, TPS76901HDBVT is an ideal voltage regulator for small digital systems and other battery-driven portable electronics.
