TPS3808G33DBVR – TEXAS INSTRUMENTS

The TPS3808G33DBVR is a single-channel, low-dropout (LDO) regulator from Texas Instruments, housed in a tiny WCSP-6 (6-pin wafer chip scale package). It’s specifically designed for applications requiring high efficiency and low quiescent current in space-constrained designs. Operating from an input voltage range of 2.7V to 5.5V, it provides a fixed 3.3V output with a maximum output current of 800mA. The device features a typical dropout voltage of only 200mV at 500mA load, maximizing battery life in portable applications._x000D_

Its internal architecture incorporates a high-efficiency switching topology, minimizing power dissipation and thermal management concerns. The TPS3808G33DBVR integrates overcurrent protection, thermal shutdown, and short-circuit protection, enhancing system robustness. Common use cases include powering microcontrollers, memory, and other low-power peripherals in battery-powered devices, portable electronics, and wearable technology. Its small footprint and high efficiency make it particularly advantageous in applications where board space is limited and power consumption is critical, offering a significant improvement over traditional linear regulators in these scenarios. The device’s excellent load transient response further contributes to its suitability for noise-sensitive applications.
