The TPS79928DRVT is a high-performance, 200-mA low-dropout (LDO) linear voltage regulator from Texas Instruments. This small-sized, efficient component is designed to provide precise voltage regulation while maintaining a low quiescent current, making it ideal for power-sensitive applications.

Key Features

• High Accuracy: The output voltage is highly accurate with a tolerance of only ±2% over the full range of load, line, and temperature variations.
• Low Dropout: With a very low dropout voltage, this device can regulate output voltages close to the supply voltage, maximizing efficiency.
• Low Quiescent Current: The TPS79928DRVT boasts a low Iq of 40 µA during active operation and 1 µA during shutdown, which aids in extending battery life in portable applications.
• Stable with Low-ESR Capacitors: The regulator is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than tantalum or aluminum electrolytic capacitors, reducing the overall solution size and cost.
• Thermal Protection: It features thermal shutdown and overcurrent protection to safeguard the device and the downstream components from damage due to overheating and excessive load conditions.
• Adjustable Voltage: The output voltage is adjustable from 1.2V to 6.5V, allowing for versatile use in various circuit designs.
• Package: The TPS79928DRVT comes in a small 6-pin SON package, ideal for space-constrained applications.
