TPS78928DBVT TI LDO Regulator | SOT-23-5 | 2.8V Output, 100mA

Product Overview

The TPS78928DBVT from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It provides a fixed output voltage of 2.8V with a maximum output current of 100mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for powering sensitive analog and digital circuits. The TPS78928DBVT features a low dropout voltage of typically 120mV at 100mA load, enabling efficient operation even when the input voltage is close to the output. It also includes built-in overcurrent and thermal shutdown protection for enhanced system reliability.
