The TPS73616DBVR is a high-performance, low-dropout (LDO) linear regulator with a wide input voltage range of between 2.2V and 5.5V. It features an ultra-low quiescent current of 0.7 μA, wide power-on reset (POR) coverage from 1.7V to 5.5V, programmable slew rate, optimized startup current and adjustable current limiter with ramping. The regulator offers superior load transient response and quick response on input voltage step changes. This makes it ideal for low-power applications with stringent electrical requirements.

The TPS73616DBVR is widely used in embedded systems. Ideal applications include powering microprocessors and digital circuits, as well as powering external components such as amplifiers, motor drivers or I/O interfaces. This device is also suitable for battery powered applications such as PoE, cigarettes and personal medical devices. It is also optimized to power applications with high load currents, which require a very low dropout voltage while maintaining a high output voltage accuracy.

The TPS73616DBVR works by converting input voltage to a regulated output voltage using an internal voltage regulator. It maintains a constant output voltage by comparing it to a reference voltage, and then adjusting the current flow through a pass element such as a FET. The regulation of the output voltage is achieved via the use of a voltage feedback loop. The error amplifier amplifies the difference between the reference voltage and the output voltage, which is then fed back to the pass element. This ensures that the output voltage remains constant, even when the input voltage fluctuates.

The TPS73616DBVR includes a slew rate protection, which limits the rate of change of the output voltage. If the voltage ramps up or down too quickly, it can cause destructive inrush currents or voltage spikes. The slew rate protection makes sure that the output voltage changes gradually, greatly reducing the chances of causing damages to the device or other connected components. It also supports an adjustable current limiter feature, which helps to protect the device from potentially damaging short-circuit events.

The TPS73616DBVR is an excellent low quiescent current linear regulator, ideal for powering low power applications with stringent electrical requirements. It features wide input voltage range and POR coverage, adjustable current limiter and ramping, and superior load transient response. Moreover, its slew rate protection ensures that the output voltage ramps up or down in a controlled manner, preventing excessive inrush currents and voltage spikes.
