TPS73001DBVR

TPS73001DBVR is a low dropout (LDO) linear voltage regulator, belonging to the family of PMIC - Voltage Regulators - Linear. It is designed for providing an adjustable voltage between 1.2V and 5.5V rail. This ldo linear regulator is specific as it comes with an active low-power shutdown feature that is used to lower down the current quiescent draw on shutdown.

In terms of its application field, the main use case of the TPS73001DBVR is the regulation of small-to-medium currents in consumer, industrial, and automotive applications such as LED lighting, smoke detectors, motor drivers, and motor control applications. This device is also worth to be noted when used as a power source in battery-powered systems.

The TPS73001DBVR works on the same principle as other linear voltage regulators. This means that it takes as input a higher voltage and applies a constant load current over a wide range of input voltages, to give a stable output from the device. To adjust the output voltage, a resistor divider network is used to provide feedback to a feedback pin on the chip, allowing the output voltage to be adjusted over a range of 1.2V to 5.5V.

The device will regulate the output in order to maintain the correct voltage, drawing a load current from the input voltage as needed to maintain the output voltage. This current draw is limited by two factors, the resistor divider network, and the output current. Using the resistor divider network to adjust the output voltage, allows the device to accurately regulate the voltage output across an input voltage range of 2V to 5.5V, while limiting the maximum output current to 500mA.

Another key feature of the TPS73001DBVR is its low-power shutdown mode, which can be used to significantly reduce the current draw on shutdown. This is done by reducing the feedback voltage to 0.1V, while still keeping the output voltage stable. With this mode enabled, the device can draw as low as 2µA on shutdown, allowing it to be used in a wide range of low-power applications.

The TPS73001DBVR is a great option for a range of low-power and low-dropout applications, due to its wide input voltage and output current ranges, and its low-power shutdown mode. The device is also quite simple to use, as its output voltage can be easily adjusted using the resistor divider network. Ultimately, the TPS73001DBVR is an excellent choice for those applications which require a low-dropout and adjustable linear voltage regulator.
