The STLQ020PUR is a highly efficient, low dropout (LDO) voltage regulator from STMicroelectronics, designed to deliver a fixed output with minimal energy loss. This component is ideal for battery-powered applications and portable devices due to its ultra-low quiescent current, which significantly extends battery life.

Key Features

• Ultra-Low Quiescent Current: The STLQ020PUR only consumes 300 nA (typical) when in operation, making it one of the most energy-efficient LDOs on the market. This feature is critical for applications where power conservation is paramount.
• Output Voltage: The device provides a stable output voltage of 2.0V, which is suitable for low-voltage electronics and can help ensure consistent performance of the powered device.
• High Accuracy: The output voltage tolerance is impressively tight, with only ±2% variation, ensuring reliable and predictable power delivery to sensitive components.
• Peak Output Current: Capable of delivering up to 200 mA, the STLQ020PUR is suitable for a range of applications that require a moderate amount of power.
• Thermal Protection: The built-in thermal shutdown function safeguards the device and the application from damage due to excessive temperatures.
• Wide Operating Temperature Range: With an operational temperature range from -40°C to +125°C, the LDO can be used in various environments, from industrial to outdoor settings.
• Small Package Size: The STLQ020PUR comes in a compact SOT323-5L package, which is ideal for space-constrained applications.
