The STMicroelectronics LK115D50-TR is a linear voltage regulator designed for low-power applications, particularly in battery-powered systems. It offers a fixed 5V output voltage with a maximum output current of 100mA.
Key electrical characteristics include a very low dropout voltage of 0.2V typical and a low quiescent current of 0.01µA in off mode and 280µA in on mode. The device also features internal current and thermal limiting for protection. It requires only a 2.2µF capacitor for stability, allowing for space and cost savings in designs.
This regulator operates within a temperature range of -40°C to 125°C and is housed in an 8-SOIC package suitable for surface mounting. It includes logic-controlled electronic shutdowns for power management, making it suitable for applications where standby power consumption is critical.
With a supply voltage rejection ratio of 80dB typical, it provides good power supply filtering. The output voltage tolerance is ±3% at 25°C.
