TL5209DR Description

Short technical summary and product information.

The Texas Instruments TL5209DR is a versatile linear voltage regulator designed for portable applications such as PDAs, laptops, and cell phones. It provides an adjustable output voltage with a maximum output current of 500mA and a dropout voltage of 0.6V at full load.

 

Key electrical characteristics include a low quiescent current of 170µA, ultra-low noise capability of 300 nV/√Hz, and tight regulation with 1% accuracy at 25°C. The device also features over-temperature, current limiting, and reverse-battery protection for enhanced reliability. Its PSRR is 75dB at 120Hz.

 

The TL5209DR is available in a compact 8-SOIC surface-mount package, making it suitable for space-constrained designs. The operating temperature range is -40°C to 125°C. It requires a minimum load of 1mA to maintain stability.
