Introduction

The TPS76901SHKQ is a low-dropout (LDO) linear voltage regulator. This device is suitable for providing up to 2 A of continuous output current when working with a minimal input-output differential. It is also suitable for providing up to 2 A of transient current during input voltage transients. The device uses a digitally-controlled, power-efficient voltage-mode architecture to support both a wide input voltage range and low output voltage ripple.

Features

The TPS76901SHKQ features a low quiescent current of 10 μA and an input voltage range of 3 V to 5.5 V on the input. It can provide up to 2 A of continuous output current and up to 1.5 A of transient current during input voltage transients. With an adjustable output voltage range of 0.8 V to 5 V, it offers more flexibility for setting the output voltage.Another feature of the TPS76901SHKQ is its protection circuitry. It includes over-current protection and reverse input voltage protection. It also has internal current-limit circuitry to prevent short circuit and current overloading, as well as thermal shutdown to protect against overheating.

Application Fields

The TPS76901SHKQ is suitable for a wide range of applications. It can be used in mobile devices and battery-powered equipment, as well as in handheld applications. This device can provide low-noise, low-voltage and constant voltage with fast transient responses.The TPS76901SHKQ can also be used in automotive applications for supplying regulated power for ECUs and other circuits. It can also provide power for embedded microcontrollers, particularly those with advanced power management systems.

Working Principle

The TPS76901SHKQ is a linear, low-dropout (LDO) voltage regulator. This device uses a digitally-controlled, power-efficient voltage-mode architecture to regulate the input voltage. This architecture allows the device to support both a wide input voltage range and low output voltage ripple.The device includes an output voltage adjust pin, which sets the final output voltage according to an external resistor divider. The device also includes an enable pin, which allows the device to be enabled (or shut down) as needed.The device uses a split-input gate to minimize the gate voltage, resulting in a low dropout voltage. This allows the device to maintain a low output voltage even when the input voltage is low.Once the output voltage is set, the TPS76901SHKQ will maintain a constant voltage on the output until the input voltage changes. When the input voltage drops, the device will reduce the current consumption to maintain a constant output voltage. This ensures that there are no output voltage transients when the input voltage transients.

Conclusion

The TPS76901SHKQ is a low-dropout linear voltage regulator. This device is suitable for providing up to 2 A of continuous output current and up to 1.5 A of transient current during input voltage transients. With an adjustable output voltage range of 0.8 V to 5 V, it offers more flexibility for setting the output voltage.The TPS76901SHKQ is suitable for a wide range of applications, including mobile devices and battery-powered equipment, handheld applications, and automotive applications for supplying regulated power for ECUs and other circuits. It can also provide power for embedded microcontrollers, particularly those with advanced power management systems.
