R1513S Series
AEC-Q100 Grade 1 Compliant
36 V, 0.8% Accuracy, 300 mA, Voltage Regulator for Automotive Applications
NO.EC-321-190829
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.

RECOMMENDED OPERATING CONDITIONS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the recommended
operating conditions, even if they are used over such conditions by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended
operating conditions.

TECHNICAL NOTES
Phase Compensation
Phase compensation is provided to secure stable operation even when the load current is varied. For this purpose,
use a 4.7 µF or more output capacitor (C2) with good frequency characteristics and proper ESR (Equivalent Series
Resistance). Connect a 1.0 µF or more input capacitor (C1) between the VDD pin and the GND pin as close as
possible to the pins.
In case of using a tantalum type capacitor with a large ESR, the output might become unstable. Evaluate your
circuit including consideration of frequency characteristics.
Depending on the capacitor size, manufacturer, and part number, the bias characteristics and the temperature
characteristics vary.
PCB Layout
Ensure the VDD and GND lines are sufficiently robust. If their impedance is too high, noise pickup or unstable
operation may result. No. 2 pin and No.5 pin must be wired together when mounting on board. Connect a
capacitor with a suitable between the VDD and GND pins, and as close as possible to the pins. The load
regulation can be improved by short-circuiting VOUT and VFB close to the load device.

R1513S
NO.EC-321-190829
Thermal Shutdown Function
Thermal shutdown function detects overheating of the regulator and stops the regulator operation to protect the
device from damage. Thermal shutdown circuit stops the regulator operation if the junction temperature becomes
higher than 160°C (Typ.) and restarts the regulator operation if the junction temperature drops below 135°C (Typ.).
The regulator repeats turning on and off and creates pulse waveform until the cause of the overheating is removed.
Adjustable Output Voltage Setting
Output voltage can be adjusted by using the external divider resistors (R1, R2). By using the following equation,
the output voltage (VOUT) can be determined. The voltage which is fixed inside the IC is described as VFB.
VOUT = VFB x ((R1 + R2) / R2)

Output Voltage Adjustment Using External Divider Resistors (R1, R2)
The minimum resistance value for a resistor (RIC) is 1 MΩ (Ta = 25°C, guaranteed by design). For better accuracy,
