TPS78227DRVTG4

Power management integrated circuits (PMICs) have become a popular choice as they are capable of controlling multiple power and voltage pathways with a single device, offering significant improvements in power efficiency, design simplicity and system performance with minimal cost. Linear voltage regulators are the basic building blocks of power system designs, providing voltage regulation and supplying current to loads. The TPS78227DRVTG4 is an advanced, low-quiescent Current (IQ) linear regulator with excellent accuracy and output current performance.

The TPS78227DRVTG4 is a cost-effective, low-power linear voltage regulator featuring an integrated shutdown control circuit, adjustable current limit, and a variety of output voltage range options. It provides extremely low quiescent current, excellent transient response and ±1.5% maximum output voltage accuracy over the entire load range. This linear regulator can be used for power supply systems powered from LiVthP or battery packs, as well as systems requiring ultra-low quiescent current or battery-backed systems.

Its wide range of functional features such as an adjustable voltage, current limit, thermal shutdown protection, under-voltage lockout and adjustable line transient response, make this device ideal for a variety of applications, including USB charging, battery management and industrial control systems. In addition, the TPS78227DRVTG4 is AEC-Q100 certified, guaranteeing that it is reliable and suitable for automotive applications.

This voltage regulator works on the principle of simple voltage regulation. It controls the output voltage by monitoring the input voltage, which is applied to its reference pin. The sense pin supplies the necessary feedback voltage to the error amplifier. The internal comparator then compares the error amplifier with the resistance divider circuit connected across the output of the regulator to maintain the output voltage as close as possible to the desired value.

In summary, the TPS78227DRVTG4 is an advanced, low-IQ linear regulator with excellent accuracy and output current performance, suitable for a variety of applications. Its wide range of functional features, such as adjustable voltage and current limit, thermal shutdown protection and adjustable line transient response make it ideal for USB charging, battery management, industrial control systems and other applications requiring ultra-low quiescent current or battery-backed systems.
