OUTLINE

The R1513S is a CMOS-based voltage regulator (VR) 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 allow the R1513S to become an ideal power source of electric home appliances.

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.
