TPS78928DBVR Voltage Regulator by Texas Instruments

The TPS78928DBVR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator that offers a robust power management solution for a wide range of applications. This compact device is designed to deliver a stable and reliable 2.8V output voltage with an input voltage range from 2.7V to 6.5V, making it ideal for battery-powered devices and other portable electronic applications.

With an impressive low dropout voltage of just 85mV at full load, the TPS78928DBVR ensures efficient operation even when the input voltage is close to the output voltage. This feature is particularly useful in extending battery life by allowing the system to operate effectively during lower battery voltages.

The TPS78928DBVR is capable of delivering up to 100mA of continuous output current, while maintaining a high level of accuracy with a 2% overall output voltage tolerance. Its low quiescent current of 17µA (typical) during operation and 1µA (typical) in shutdown mode further enhances its suitability for power-sensitive applications.

One of the key features of this LDO is its thermal performance. The device is designed with an over-temperature protection mechanism that safeguards the regulator and the system it powers from excessive heat. Additionally, the TPS78928DBVR includes over-current protection to prevent damage from high current conditions, ensuring reliable operation and a longer life for the end product.

The TPS78928DBVR comes in a small SOT-23-5 package, which is highly valued in space-constrained designs. Its small footprint does not compromise its performance or functionality, making it an excellent choice for portable electronics, such as wearables, smartphones, and medical devices. The device also features low noise operation, which is critical for RF and precision analog circuits that demand a clean power supply.

Overall, the TPS78928DBVR from Texas Instruments is a versatile and efficient solution for a variety of low-power applications that require a stable and precise voltage supply. Its combination of low dropout, high accuracy, and protective features make it a reliable choice for designers looking to optimize their power management systems.
