In the ever-increasing complexity of today’s systems, power-supply management and monitoring are critically important. An appropriately chosen linear voltage regulator can provide flexible and reliable power for the wide variety of devices that make up the system, from low-power microcontrollers to high-power displays, from interface circuits to communication controllers. The Texas Instruments TPS7A8101DRB linear regulator is a good choice for achieving power-supply management and monitoring.

TPS7A8101DRBT is a 1A SOT-23 linear regulator (4.7V-41V) that offers a wide voltage range for a wide range of applications, including automotive, industrial, medical, and consumer systems. The device can be used to provide stable voltage supply to on-board circuits, and the built-in protection function prevents the device from being over-current. This feature ensures that the system is not affected if the input power is greater than the expected value.

The operating temperature range of the TPS7A8101DRBT is −40°C to +125°C, making it suitable for operation in harsh conditions. The maximum current of up to 150mA ensures that the device can handle higher current conditions, making it suitable for a range of power output applications. The device also offers high ripple rejection, making it suitable for use in sensitive applications where noise is a concern.

The design of the TPS7A8101DRBT is based on the classic linear regulator topology, which has two main components – an amplifier and a power transistor. The internal feedback loop reduces output voltage variations caused by temperature and load changes. The amplifier collects the output voltage information to adjust the power transistor to the required output voltage.

In addition to its core function, the TPS7A8101DRBT also includes an Under Voltage Lockout (UVLO) feature, which is designed to protect the device from excessive input voltage. The UVLO feature shuts down the device if the input voltage is too low, preventing the system from running under dangerous conditions.

The TPS7A8101DRBT also includes an integrated thermal shutdown function. This feature is designed to protect the device from over-temperature conditions. When the thermal shutdown feature is activated, the output of the device will be completely shut down to protect the device from damage.

The TPS7A8101DRBT linear regulator offers high performance, flexibility, and reliability for a wide range of applications. The integrated protection features and wide input voltage range make the device suitable for use in a range of powering applications. The device also provides high efficiency and ripple rejection, making it suitable for a range of high-sensitivity applications.
