R1513S SeriesAEC-Q100 Compliant

36V, 0.8% Accuracy, 300mA, Voltage Regulator for Automotive Applications


Data Sheet

Data Sheet

The R1513S is a CMOS-based voltage regulator (VR) that specifically designed for automotive applications featuring 300mA output current and 36V input voltage. Internally, the R1513S consists of a fold-back protection circuit, a short current protection circuit and a thermal shutdown circuit in addition to the basic regulator circuit.
The performance is specified for 25°C with ±0.8% output voltage accuracy and for the −40°C to 125°C temperature range with ±1.0% output voltage accuracy. The operating temperature range is −40°C to 125°C and the maximum input voltage is 36V. All these features make the R1513S ideal for power source for car accessories and electronic control units in automotive vehicles.
The R1513S is available in 1.2V, 1.5V, 1.8V, 3.3V, 3.4V and 5.0V fixed output voltage options. By using external divider resistors, the output voltage can be set over a 1.2V to 18.0V range.
The R1513S is offered in a 6-pin HSOP-6J high wattage package.
