TPS71533DCKR Description

Short technical summary and product information.

The TPS71533DCKR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for efficient power management. It features a wide input voltage range from 2.5V to 24V, capable of handling up to 30V for new chips. This device delivers a stable, fixed 3.3V output voltage with a maximum output current of 50mA.

A key characteristic of the TPS71533DCKR is its ultra-low quiescent current of just 3.2µA at a 50mA load, making it suitable for battery-powered applications where power conservation is critical. It offers a typical dropout voltage of 415mV at 50mA and includes overcurrent protection for enhanced reliability.

The regulator is stable with a minimum output capacitance of 0.47µF. It operates across a wide temperature range of -40°C to 125°C. The TPS71533DCKR is supplied in a compact 5-pin SC-70 (SOT-353) surface-mount package, ideal for space-constrained designs.

This LDO regulator is well-suited for various applications requiring a clean and stable voltage supply, such as portable electronics, battery management systems, and general-purpose power regulation.
