TPS73201DBVR

TPS73201DBVR Voltage Regulator Linear Application Field and Working Principle

The TPS73201DBVR is a low-noise, high-accuracy, low-dropout linear voltage regulator designed for low power consumption applications. The device is available in an adjustable and fixed versions. The adjustable versions have an output voltage range from 0.8 V to 1.8 V and have a line regulation of 0.2% and a maximum load current of 500mA. The fixed versions have a reference voltage from 1.25V to 1.85V and have a line regulation of 0.5% and a maximum load current of 200mA. The TPS73201DBVR is designed for high power efficiency (greater than 92%) and low quiescent current (2.2mA). It also has protection against current overload, reverse current flow and reverse voltages.

The TPS73201DBVR voltage regulator uses an advanced linear circuit topology that optimizes high accuracy regulation and low noise performance. This advanced linear circuit topology offers the advantages of both switching and linear regulators to reduce noise and power consumption while maintaining a high load current capability and high efficiency. The TPS73201DBVR includes two independent error amplifiers, one with a reference voltage of 1.25V and the other with a reference voltage of 1.85V, that control the source and sink current of the regulator. The output of the error amplifiers are compared to the input voltage, and the output is adjusted accordingly. The output voltage can also be adjusted by a control voltage, which is connected to the Adjust pin.

The TPS73201DBVR is designed for applications such as power supplies for embedded systems, handheld devices, digital signal processors (DSPs) and other low power systems. The device is offered in a small, leadless package and is specified over -40°C to +125°C. It also includes an enable pin that allows the user to turn the device off and save power.
