Additional Details

The NJM2847F3-011-TE1 typically supports an input voltage range of 2.5V to 6.0V and delivers a fixed output voltage, commonly around 1.1V, but the exact value depends on the specific variant. The dropout voltage is typically less than 0.2V at the rated output current. This LDO also features a built-in short-circuit protection and over-temperature protection. The operating temperature range is usually from -40°C to +85°C. The package is a small SOT-23 or similar surface-mount package. The specific output voltage and other parameters should be verified from the manufacturer's datasheet for the exact model number.
