TLV73330PDBVT TI LDO Regulator | SOT-23-5 | 3.3V Output, 300mA

Product Overview

The TLV73330PDBVT is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 3.3V with a maximum output current of 300mA. Housed in a compact SOT-23-5 package, this device is designed for space-constrained applications requiring high accuracy and low quiescent current. With a dropout voltage as low as 130mV at full load, it ensures efficient power conversion even under low input-to-output voltage differentials. The TLV73330PDBVT features a wide input voltage range from 1.4V to 5.5V, making it suitable for battery-powered and portable electronics. Its low quiescent current of 34µA (typical) extends battery life in standby modes. The device also includes built-in overcurrent and thermal shutdown protection, enhancing system reliability.
