300mA 36V Input Regulator for Automotive Applications
The R1511x is a CMOS-based high-voltage resistant and fast response voltage regulator that provides the minimum 300mA of output current. Internally, R1511x consists of an Output Short-circuit Protection Circuit, an Over-current Protection Circuit, and a Thermal Shutdown Circuit in addition to the basic regulator circuits. The operating temperature range is between –40ºC to 125ºC, and the maximum input voltage is 36V. All these features allow the R1511x to become an ideal power source for car accessories and ECUs.
R1511x is available in R1511xxxxB with the fixed output voltage type, and R1511x001C with adjustable output voltage type with external resistors. The output voltage accuracy is ±1.0%.
R1511x is available in two types of packages for ultra high wattage: HSOP-6J and TO-252-5-P2.
