SK100EL34WD is a voltage regulator from Semtech, specifically designed for low input voltage and low current applications. It is a step-up DC to DC converter that provides a regulated adjustable output voltage up to 7.5 V. The device is offered in an analog control version, providing adjustable output voltage, as well as a PWM-to-analog configuration that provides a regulated output voltage based on the duty cycle of the input pulse. The integrated features include over temperature protection, over voltage protection, over load protection and automatic load-line regulation. The maximum operating temperature range of the SK100EL34WD is -40°C to 125°C.
