R1514x Series CMOS Voltage Regulator
Voltage Regulator with 150mA Output Current and 36V Input Voltage
The currently available information as of December 2009 is provided in this New Product News. EK-152-091101
●Volt age Regulator with 150mA Output and 36V Input Voltage
MAXIMUM INPUT VOLTAGE 36V
The CMOS type regulator has been introduced into the
high input voltage area where only bipolar type could
previously operate.
The R1514x Series have achieved the absolute
maximum rating as high as 50V (peak input voltage: 60V
< 200ms).
LOW SUPPLY CURRENT
DURING OPERATION: 9μA
This value represents the world’s lowest supply current of
regulators with an input voltage of 36V.
A battery saving system can be built, because the supply
current is low in the operating mode as well as in standby
mode.
MAXIMUM OPERATING AMBIENT
TEMPERATURE 105
°
C
Unlike Ricoh’s conventional regulators, the operating
ambient temperature range of the R1514x Series is rated
from -40°C to 105°C that makes it suitable for use in
automotive and industrial applications involving higher
operating temperatures.

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 of the output pin (VOUT) and ground pin (GND).
The Thermal Shutdown Circuit stops operation of the regulator when the junction temperature of the regulator exceeds 150°C. Moreover, when the
junction temperature decreases to a level below 125°C after the regulator has stopped, the regulator resumes to normal operation.
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. Care should be taken to prevent this situation.
In the datasheet it is shown as a thermal shutdown detection temperature (TTSD) and a thermal shutdown release temperature (TTSR).
