R1524x Series
200 mA 36 V Input Ultra Low Supply Current VR
No. EA-332-200310
OUTLINE
The R1524x is an ultra-low supply current voltage regulator featuring 200 mA output current and 36 V input
voltage. This device 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
from −40°C to 105°C, and the maximum input voltage is 36 V. All these features allow the R1524x to become
an ideal power source of electric home appliances.
The output voltages are internally fixed (refer to SELECTION GUIDE). The output voltage accuracy is ±0.6%.
The packages for this device range from high-density mounting to ultra high wattage. The R1524x is offered
in five packages; a 5-pin SOT-23-5, a 5-pin SOT-89-5, a 6-pin HSOP-6J, a 6-pin DFN(PLP)1820-6, and an 8pin HSOP-8E 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.

THEORY OF OPERATION
Thermal Shutdown
R1524x has a built-in thermal shutdown circuit, which stops the regulator operation if the junction temperature
of this device increases to 160°C (Typ.) or higher. If the temperature drops to 135°C (Typ.) or lower, the
regulator restarts the operation. Unless eliminating the overheating problem, the regulator turns on and off
repeatedly and as a result, a pulse shaped output voltage is generated.

TECHNICAL NOTES
Phase Compensation
In the R1524x, phase compensation is provided to secure stable operation even when the load current is
varied. For this purpose, make sure to use 0.1 μF or more of a capacitor (C2).
In case of using a tantalum type capacitor and the ESR (Equivalent Series Resistance) value of the capacitor
is large, the output might be unstable. Evaluate the circuit including consideration of frequency characteristics.
Connect 0.1 μF or more of a capacitor (C1) between VDD and GND, and as close as possible to the pins.
PCB Layout
For SOT-23-5 package type, wire the following GND pins together: No. 1 and No. 2
For SOT-89-5 package type, wire the following GND pins together: No. 2 and No. 4.
For HSOP-6J package type, wire the following GND pins together: No. 2, No. 4, and No. 5.

Input Transient/Load Transient vs. Output Capacity (C2)
R1524 performs a stable operation by using 0.1 µF of ceramic capacitor as the output capacitor. However,
the variation of output voltage may not meet the demand of the system when input voltage and load current
vary. In such cases, the variation of output voltage can be minimized significantly by using 10 µF or higher
ceramic capacitor. When using an electrolytic capacitor for the output line, place the electrolytic capacitor
outer side of the ceramic capacitor arranged close to the IC.
