R1513S Series
AEC-Q100 Grade 1 Certified
36 V, 0.8% Accuracy, 300 mA, Voltage Regulator for Automotive Applications
NO.EC-321-140124
OUTLINE
The R1513S is a CMOS-based voltage regulator (VR) that specifically designed for automotive applications
featuring 300 mA output current and 36 V 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 36 V. 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 1.2 V, 1.5 V, 1.8 V, 3.3 V, 3.4 V and 5.0 V fixed output voltage options. By using
external divider resistors, the output voltage can be set over a 1.2 V to 18.0 V range.
The R1513S is offered in a 6-pin HSOP-6J high wattage package.
