TPS76933

The Texas Instruments TPS76933 is a versatile low-dropout (LDO) linear voltage regulator capable of delivering up to 100mA of output current. It features a low quiescent current of 17µA typical, making it suitable for power-sensitive applications. The device includes an enable pin for power sequencing and control.

With an input voltage range of 2.5V to 16V (new chip) and output voltage options from 1.2V to 5.5V, the TPS76933 provides flexibility for various designs. It offers a typical dropout voltage of 71mV at 100mA for the legacy version and 215mV for the new chip, ensuring efficient regulation. The regulator also boasts a PSRR of 27dB at 100 KHz, with newer versions offering 46dB at 1MHz, helping to reduce noise in sensitive circuits.

Integrated fault protection, including thermal shutdown and overcurrent protection, enhances reliability. The TPS76933 is available in a compact 5-pin SOT-23 package, ideal for space-constrained applications. It requires a minimum load capacitance of 4.7µF for the legacy chip and 2.2µF for the new chip for stable operation.

This LDO regulator is well-suited for battery-powered devices, portable electronics, and other applications requiring a stable and efficient voltage supply. Its combination of low power consumption, small footprint, and robust protection features makes it a reliable choice for power management solutions.
