Frequently Asked Questions
How much output current can the LP2951CM-3.3/NOPB supply?
The LP2951CM-3.3/NOPB delivers up to 100mA continuous output current. It maintains regulation down to a dropout voltage of approximately 600mV at full load, making it suitable for low-supply-rail applications where headroom is limited.
Does LP2951CM-3.3/NOPB include a power-good or error flag output?
Yes. The device has a dedicated open-drain error flag pin that asserts low when the output voltage falls more than approximately 6% below the set voltage, enabling the host MCU to detect under-voltage or overload conditions without an external supervisor IC.
What is the input voltage range for LP2951CM-3.3/NOPB?
The regulator accepts an input voltage from 2.5V up to 30V, giving designers flexibility to use it directly from unregulated supplies, Li-ion batteries, or automotive 12V rails while delivering a clean 3.3V output.
Can LP2951CM-3.3/NOPB be used in automotive or industrial designs?
Yes. Its industrial-grade temperature range of -40°C to +125°C and wide input range make it well suited for automotive accessory circuits, industrial sensors, and equipment operating in harsh thermal environments.
What alternatives are compatible with LP2951CM-3.3/NOPB?
Pin-compatible or functionally equivalent alternatives include the LP2951ACMX-3.3/NOPB (higher accuracy ±0.5% variant) and the LP2985-33DBVR (SOT-23 form factor for space-constrained boards). The MIC5205-3.3YM5 is also a common second-source substitute.
