Frequently Asked Questions
What is the dropout voltage of the LM2931CM?
The LM2931CM has a low dropout voltage of approximately 0.6V at full load (100mA output current). This low dropout characteristic allows the regulator to maintain stable output even when the input voltage is only slightly higher than the output, making it ideal for battery-powered applications where maximizing battery runtime is critical.
What is the maximum input voltage for the LM2931CM?
The LM2931CM supports a maximum input voltage of 26V, with an operating input range of 3V to 26V. This wide input voltage range makes it suitable for automotive applications, industrial equipment, and systems powered from unregulated or variable power supplies where input voltage can fluctuate significantly.
What package does the LM2931CM come in?
The LM2931CM is available in a compact SOT-23 surface-mount package. This small footprint package is ideal for space-constrained PCB designs in portable electronics, wearables, and densely packed circuit boards. The M suffix designates the SOT-23 package variant of the LM2931 regulator family.
What are typical applications for the LM2931CM?
The LM2931CM is commonly used in battery-powered devices such as handheld instruments, IoT sensors, and portable consumer electronics. It is also suitable for automotive systems (operating across the 3V–26V range), industrial control boards, microcontroller power rails, and any application requiring a reliable 100mA regulated output with minimal dropout.
