R1524x-Y Series
200 mA 36 V Input Ultra Low Supply Current VR for Industrial Applications
No. EA-354-170908
OUTLINE
The R1524x is a CMOS-based 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 between
−50°C
to 125°C, and the maximum input voltage is 36 V. All these features allow this device to
become an ideal power source for equipments used under high-temperature conditions.
The output voltages are internally fixed at either of the following: 1.8 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V, 3.4 V, 5.0 V,
5.5 V, 6.0 V, 6.4 V, 8.0 V, 8.5 V and 9.0 V. 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 8-pin
HSOP-8E package.
This is a high-reliability semiconductor device for industrial applications (-Y) that has passed both the
screening at high temperature and the reliability test with extended hours. This line of products operate in a wide
temperature range from low temperature to high temperature to support harsh environment applications.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent
damages and may degrade the lifetime and safety for both device and system using the device in the field. The functional
operation at or over these absolute maximum ratings are not assured.

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 when 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.
