The LP3986-25B3F is a Low Dropout (LDO) Regulator SOT23-3 RoHS device manufactured by LOWPOWER. It is used to provide consistent, stable, and low-loss voltage regulation for system circuits requiring controlled current or voltage. It can be used as an output voltage regulator or as part of a power management system. It integrates an enhanced 25V output among its features. It also has a wide input voltage range from 2.5V to 6V, a very low minimum dropout voltage of 0.22V, and an operating temperature range from -40°C to 125°C. The LP3986-25B3F also features integrated over-temperature, current-limit and short-circuit protection to ensure safe operation without the need for external components.
