STLQ50C33R Description

Short technical summary and product information.

The STMicroelectronics STLQ50C33R is a high-performance LDO (Low-Dropout) voltage regulator. It provides a stable 3.3V output voltage with a maximum output current of 50mA. The device features a low dropout voltage of 700mV at 50mA, making it suitable for battery-powered applications where voltage efficiency is critical.

 

With an input voltage range from 2.3V to 12V, the STLQ50C33R offers flexibility in power source selection. It includes protection features such as over-current and over-temperature protection, enhancing system reliability. The regulator exhibits good line and load regulation, with PSRR of 30dB at 120Hz.

 

Packaged in a compact SOT-323-5 surface-mount case, this component is ideal for space-constrained designs. The operating temperature range is -40°C to 150°C, ensuring performance in various environmental conditions. Mounting is via surface mount technology.

 

Key electrical characteristics include a 3.3V fixed output, 50mA output current, and a wide input voltage range. The low quiescent current and high PSRR make it suitable for noise-sensitive applications.
