R1515x Series
50mA 36V Input Low Supply Current VR
The R1515x Series are CMOS-based voltage regulators featuring 50mA output current and 36V input voltage. In addition to a
fold-back protection circuit built into conventional regulators, R1515x contains a thermal shutdown circuit. Besides the low supply
current by CMOS, the operating temperature is -40°C to 105°C and the maximum input voltage is 36V, the R1515x series are very
suitable for power source of car accessories∗.
∗) These products are suitable for automotive applications too. Please refer to our "Car Electronics Products Catalog" or contact us.

CMOS Voltage Regulator
R1515x Series
50mA 36V Input Low Supply Current VR
CMOS Voltage Regulator
MAXIMUM INPUT VOLTAGE 36V
The CMOS type regulator has been introduced into the
high input voltage area where only bipolar type could
serve previously operate.
CMOOSS ttyppee hhiigghh iinnppuutt vvoollttaaggee aarreeaa
The R1515x Series have achieved the absolute maximum
rating as high as 50V (peak input voltage: 60V<200ms).
Absolute Maximum Rating 50V
(Peak Input Voltage 60V)
LOW SUPPLY CURRING DURING
OPERATIOPERATION: 9μA
Supply current is only one-tenth to one-fortieth of that of
the bipolar type.
This value represents the world’s lowest supply current of
regulators with an input voltage of 36V.
A battery friendly system can be built, because supply
current is low in both operating mode as well as in
standby mode.

MAXIMUM OPERATING AMBIENT
TEMPERATURE 105°C
CMOOSS ttype large current range
Unlike Ricoh’s conventional regulators, the operating
ambient temperature range of the R1515x Series is rated
from -40°C to 105°C that make it suitable for use in
automotive and industrial applications involving higher
temperature.
Output current (mA)
Thermal Shutdown Circuit
The thermal shutdown circuit shown in the block diagram detects an increase in temperature, stops operation, and protects the regulator from being
damaged by a short circuit in the output pin (VOUT) and ground pin (GND).
For example, the Thermal Shutdown Circuit stops regulator operation if the junction temperature of the R1515x Series becomes higher than 150°C.
Additionally, if the junction temperature after the regulator being stopped decreases to a level below 125°C, it restarts regulator operation.
(The temperature is different according to the product.)
As a result the operation of the Thermal Shutdown Circuit causes the regulator repeatedly to turn OFF and ON till the causes of overheating are
removed. As a consequence a pulse shaped output voltage occurs. Please prevent this situation.
In the datasheet it is shown as a thermal shutdown detection temperature (TTSD) and a thermal shutdown release temperature (TTSR).
