Product Overview: TPS79901DRVRG4

The TPS79901DRVRG4 is a highly efficient, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a stable and precise output voltage for a wide range of applications. Boasting a low quiescent current and excellent transient performance, this regulator is particularly suitable for battery-powered devices, where power conservation is paramount.

Key Features

• High Accuracy: The TPS79901DRVRG4 offers an impressive output voltage accuracy of 2%, ensuring reliable performance for sensitive electronic components that require a consistent power supply.
• Low Dropout: With a low dropout voltage of typically 40 mV at 200 mA load, this LDO can operate effectively even when the input voltage is very close to the output voltage, making it ideal for scenarios with limited power.
• Adjustable Output: Users can adjust the output voltage from 1.2 V to 6.5 V using external resistors, providing flexibility for different circuit requirements.
• Stable with Ceramic Capacitors: The device is stable with ceramic output capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) compared to their tantalum counterparts.
• Low Quiescent Current: The TPS79901DRVRG4 has a low quiescent current of 40 µA (typical), which is beneficial for extending battery life in portable applications.
• Thermal Shutdown and Overcurrent Protection: Built-in safety features include thermal shutdown and overcurrent protection, enhancing the durability and lifespan of both the regulator and the overall system.
• Small Package Size: The device comes in a compact SON-6 package, which is ideal for space-constrained applications.
