Product Overview: Texas Instruments TPS76628DR

The TPS76628DR is a highly efficient, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed output of 2.8V with an input voltage range of 2.7V to 10V. This regulator is capable of supplying up to 250mA of output current, making it an excellent choice for portable and battery-powered applications where power efficiency is crucial.

The TPS76628DR comes in a compact SOIC-8 package, which is suitable for space-constrained applications. Its small footprint does not compromise its performance; the device offers excellent regulation and transient response, ensuring stable voltage supply even during sudden changes in load.

Key Features

• Low Dropout: The TPS76628DR provides a low dropout voltage, which ensures efficient operation even when the input voltage is close to the output voltage, thus maximizing battery life in portable applications.
• High Accuracy: With an output voltage tolerance of ±2%, this regulator maintains precise voltage regulation under varying conditions.
• Thermal Protection: The device includes built-in thermal shutdown protection, which helps to prevent damage from overheating by automatically turning off the regulator if the internal temperature exceeds the safe threshold.
• Overcurrent Protection: The current limit feature protects the regulator and the load from damage in the event of a short circuit or excessive load conditions.
• Low Noise: The TPS76628DR is optimized for low noise operation, making it ideal for sensitive RF or analog circuits that require a clean power supply.
• Stable with Low ESR Capacitors: The device is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than tantalum or aluminum electrolytic capacitors, providing improved transient response and reducing output noise.

Applications

The TPS76628DR is versatile and can be used in a wide range of applications, including:

• Portable/battery-powered devices
• Wireless communication systems
• PDAs and mobile phones
• Digital cameras and audio devices
• Microcontroller power supplies

With its combination of low dropout, high accuracy, and protection features, the TPS76628DR from Texas Instruments is a robust and reliable choice for designers looking to optimize their power management solutions.
