The TLV74328PDBVR is a high-performance, low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments (TI). Belonging to the TLV743P series, this power management IC features a fixed 2.8V output voltage, a maximum output current of 300mA, and an input voltage range of 1.4V to 5.5V, providing an efficient and reliable power regulation solution for compact electronic devices.
Designed for low-power applications, the TLV74328PDBVR features a typical quiescent current of only 34µA, helping reduce power consumption and extend battery operating life. Its low-dropout architecture supports efficient voltage regulation when the input voltage is close to the required output voltage.
The device offers typical output voltage accuracy of ±1% and a maximum accuracy specification of ±1.4%. It is designed for stable operation with a 1µF ceramic output capacitor, minimizing external component requirements and simplifying PCB design.
The TLV74328PDBVR integrates an enable function, active output discharge, foldback overcurrent protection, undervoltage lockout, and thermal shutdown protection. These features help improve power management reliability and protect electronic systems under abnormal operating conditions.
Housed in a compact 5-pin SOT-23 (DBV) surface-mount package, the regulator supports space-efficient PCB layouts and automated SMT assembly. Its operating junction temperature range of -40°C to +125°C makes it suitable for industrial electronics, portable devices, embedded systems, and battery-powered applications.
