TPS76833QPWPG4 – TEXAS INSTRUMENTS

The TPS76833QPWPG4 is a low-dropout (LDO) voltage regulator from Texas Instruments, housed in a space-saving 4x4mm QFN (PWPG4) package. It’s specifically designed for applications requiring high efficiency and low noise at low output currents. Operating from an input voltage range of 2.5V to 5.5V, it provides a precisely regulated output voltage, adjustable via an external resistor divider, typically ranging from 0.8V to 5.0V. The device features a quiescent current of only 25µA, making it ideal for battery-powered systems. Its low output noise (typically 20µVrms) is crucial for sensitive analog circuitry._x000D_

The TPS76833QPWPG4 incorporates a unique architecture minimizing output voltage ripple and ensuring excellent transient response. It features overcurrent protection, thermal shutdown, and short-circuit protection, enhancing system reliability. Common applications include powering sensitive analog-to-digital converters (ADCs), microcontrollers in low-power modes, and other precision analog circuits where low noise and high efficiency are paramount. Its small footprint and robust protection mechanisms make it a superior choice compared to older LDO technologies in space-constrained, battery-operated designs needing stable, low-noise power. The device’s high PSRR (power supply rejection ratio) further minimizes the impact of input voltage fluctuations on the output.
