The TPS79928DBVR from Texas Instruments is a highly efficient, low-dropout linear regulator (LDO) capable of delivering a maximum of 200 mA of continuous output current. This small-footprint device is ideal for space-constrained applications and is designed to maintain high performance across a wide range of operating conditions.
Key Features
- High Accuracy: With an output voltage accuracy of 2%, the TPS79928DBVR ensures precise voltage delivery for sensitive components.
- Low Dropout: The regulator boasts a very low dropout voltage, typically just 40 mV at 200 mA of load current, which enhances efficiency and allows operation closer to the battery's end-of-life voltage.
- Low Quiescent Current: It has an ultra-low quiescent current of 40 µA during operation and 1 µA in shutdown mode, making it suitable for battery-powered and energy-saving applications.
- Stable with Ceramic Capacitors: The device is stable with ceramic output capacitors, which are small in size, have lower equivalent series resistance (ESR), and are more reliable over temperature changes compared to tantalum or aluminum electrolytic capacitors.
- Thermal Protection: The TPS79928DBVR includes over-temperature protection to safeguard the device under abnormal thermal operating conditions.
- Overcurrent Protection: Built-in current limit protection prevents damage to the regulator during fault conditions.
