The TPS73533DRBR is a low-RDS(on) linear voltage regulator ideal for providing post-regulation to any voltage supplied from a switch-mode power supply. Offering very fast transient response, the TPS73533DRBR linear regulator enables circuit designers to reduce the output ripple, further enhancing the DC output accuracy. With a maximum output current of 3A and low noise, the TPS73533DRBR is an ideal choice for all low power, low noise applications.

The TPS73533DRBR is designed to be capable of delivering up to 3A of output current with very few external components. It uses a linear PNP-type pass element to regulate its output. This allows the regulator to operate without the need for additional high-side transistors or power switches, making it highly compact and efficient. The device offers an adjustable output voltage range of 0.6 to 12V, and it is also capable of providing an output that is adjustable down to 0.125V.

The TPS73533DRBR\'s high efficiency design and low operating temperature allow it to be used in applications such as DDR-II, Flash, NAND, and low power embedded microcontrollers. Its fast response and low noise features make it suitable for communications, medical, and consumer electronic applications. Another key feature of the TPS73533DRBR is its low-dropout regulator, which allows the device to operate even with low input voltages. This makes it ideal for applications involving non-stable sources, such as battery-powered devices.

In operation, the device switches on when the supply voltage is higher than the desired regulator output voltage, allowing it to regulate the voltage accurately. If the input voltage drops below the output voltage, the device switches off and stops regulating the output voltage. This switching action helps to maintain high efficiency and reduce the power loss.

The TPS73533DRBR utilizes a feedback loop to maintain the output voltage within tolerance. The feedback loop monitors the output voltage and adjusts it according to the various conditions present. The feedback loop also offers surge current protection, allowing the device to maintain constant output levels even during extreme load conditions.

In addition to its linear regulator capabilities, the TPS73533DRBR also features a low output noise and fast transient response, making it ideal for multimedia consumer applications. The device also features a thermal shutdown feature, which guards against thermal overloads and potential hazards.

The TPS73533DRBR is an excellent choice for low power and low current applications that require a consistently regulated voltage. Thanks to its fast transient response, low noise, and adjustable output voltage range, the TPS73533DRBR is ideally suited for low-power, embedded, and consumer applications.
