TPS71530DCKR – TEXAS INSTRUMENTS

The TPS71530DCKR is a Texas Instruments low-dropout (LDO) voltage regulator in a thermally enhanced 10-pin WCSP (WSON) package. It offers a fixed 3.3V output voltage with a maximum output current of 150mA. Its input voltage range spans 3.5V to 5.5V, making it suitable for applications powered by single-cell Li-ion batteries or 3.3V logic supplies. The device features a quiescent current of only 25µA, crucial for battery-powered designs prioritizing extended runtime. _x000D_

The TPS71530DCKR employs a low-noise architecture, resulting in an output voltage ripple and noise of typically 30µVrms, beneficial for sensitive analog circuitry. Its robust protection features include overcurrent, overtemperature, and short-circuit protection, enhancing system reliability. Common use cases include powering microcontrollers, memory chips, and other low-power peripherals in portable devices, industrial sensors, and medical equipment where space and efficiency are paramount. Its small footprint and high efficiency, exceeding 90% at nominal load, make it a superior choice compared to switching regulators in applications requiring low noise and simple design implementation, eliminating the need for external components like inductors.
