TPS73801DCQR is a low-dropout linear regulator (LDO) ideal for use cases that require a small package size and low quiescent current. The regulator is capable of sourcing up to 150 mA of output current and features a Shutdown function, current limit, short-circuit protection, thermal protection, and reverse battery protection. The device can be configured to provide output voltage levels ranging from 1.8V to 6.5V.

Application Field of of TPS73801DCQR

The TPS73801DCQR’s low power requirements and wide input range enables its operation from a single cell Li-Ion or Li-Pol battery. The device is suitable for a variety of applications such as MyCelular/gaming/systems, Ultrabooks/IoT/Peripheral, MP3/GPS/Wearables, VoIP/USB Hub/HDD, and Solid-State-Drive/Digital Camera/Displays.

Working Principle of TPS73801DCQR

The working of the TPS73801DCQR is based on a voltage regulator IC that functions as a low-dropout (LDO) linear regulator. It is designed to receive input voltage from a source such as a battery and to output a constant voltage to the load. In linear regulator, the voltage is regulated by monitoring the voltage at the output and adjusting the current with a feedback loop. This loop constantly readjusts the output voltage to the desired level by adjusting the current drawn from input source.

The TPS73801DCQR features a few advanced features available such as current limit, short-circuit protection, thermal shutdown, and reverse battery protection. The device\'s current limit is adjustable and can range from 0.2mA to 150mA. The device operates with a maximum input voltage of 8V. The device also has an integrated shutdown pin that can be used to turn the device off. The device also includes over-temperature protection which will shut it down if the temperature exceeds a certain limit.

The TPS73801DCQR has a very low quiescent current draw of typically 30uA, making it an ideal choice for today\'s mobile devices that require low power consumption. It also has a wide operating temperature range of -40°C to +125°C. Overall, the TPS73801DCQR is an ideal choice for applications that require a small package size, low power consumption, and a low dropout linear regulator.
