Product Overview
The TPS78918DBVR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed to deliver a fixed 1.8V output 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 space-constrained applications requiring a stable power supply. With a dropout voltage as low as 120mV at 100mA load, it ensures efficient operation even when the input voltage is close to the output. The TPS78918DBVR integrates overcurrent and overtemperature protection, enhancing system reliability.
