The LP3986-18B3F is a Low Dropout Regulators (LDO) SOT23-3 RoHS from LOWPOWER. It is a linear voltage regulator that provides a regulated output voltage in the range of 0.8V to 18V with a typical dropout voltage of 300mV. It is designed to maintain stable and low quiescent current (ISB) over wide load and line-regulator conditions. Its on-chip protection includes current limiting and thermal shutdown, making it suitable for applications with limited space. It also includes a logic-level shutdown. The LP3986-18B3F is RoHS compliant and does not contain any hazardous materials, making it safe for use even in harsh environments.
