MP2018 is a 16 V, 500 mA, low quiescent current linear regulator

MPS’ MP2018 is a 16 V, 500 mA, low quiescent current linear regulator that features thermal shutdown and short-circuit protection (SCP)

The MP2018 from Monolithic Power Systems is a low-power, linear regulator that supplies power to systems with high-voltage batteries. This device includes a wide 3 V to 16 V input voltage range, low dropout voltage, and low quiescent supply current. The low quiescent current and low dropout voltage allow the MP2018 to operate at extremely low power levels, making it ideal for low-power microcontrollers and battery-powered equipment. The device is available in 3.3 V and 5 V fixed output voltage options. The regulator output current is limited internally and the device is protected against short-circuit, overload, and overtemperature conditions. The MP2018 also includes thermal shutdown and current-limiting fault protection and is available in a TO252-5 package.
