Product Overview: Texas Instruments TPS76333DBVT

The Texas Instruments TPS76333DBVT is a high-precision, low-dropout voltage regulator that offers the benefits of low dropout voltage, low-power operation, and miniaturized packaging. This regulator is specifically designed to deliver a fixed output voltage of 3.3V with an output tolerance of +/-2% over the entire load, line, and temperature range. It is capable of providing an output current of up to 150 mA, making it suitable for a variety of applications including battery-powered devices, handheld equipment, and portable consumer electronics.

With a dropout voltage of typically just 200mV at full load, the TPS76333DBVT ensures efficient operation even when the input voltage is close to the output voltage, thereby extending battery life in portable applications. The regulator also features a low quiescent current of 85 µA (typical) in operation and less than 1 µA in shutdown mode, further optimizing power consumption for battery-sensitive designs.

The device comes in a compact SOT-23-5 package, which is ideal for space-constrained applications. The small footprint of the package, combined with the low number of external components required, makes the TPS76333DBVT a perfect choice for portable and space-limited designs.

For added reliability, the TPS76333DBVT includes built-in protection features such as over-current protection, thermal shutdown, and reverse battery protection. These features ensure that the device and the system it is a part of are safeguarded against a range of potential issues that could arise during operation.
