STLQ020C33R

STLQ020C33R Description

The STLQ020C33R from STMicroelectronics is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver a fixed 3.3V output with a maximum output current of 200mA. This surface-mount device, packaged in a compact SOT323-5 form factor, is optimized for power-sensitive applications requiring stable voltage regulation with minimal quiescent current. With an ultra-low dropout voltage of 0.16V at 200mA, it ensures efficient operation even with tight input-output differentials. The regulator supports an input voltage range up to 5.5V, making it suitable for battery-powered and portable electronics. Its ROHS3 compliance and REACH unaffected status ensure environmental and regulatory adherence.
