Data Sheet

Data Sheet

The R1514x is a CMOS-based positive voltage regulator (VR) IC featuring 150mA output current. It is specifically designed for automotive applications. The R1514xxxxB has features of high input voltage and ultralow supply current. A peak current limit circuit, a short current limit circuit, and a thermal shutdown circuit are built in the R1514x.
The operating temperature is −40°C to 105°C and the maximum input voltage is 36 V, the 1514x is very suitable for power source of car accessories.
The regulator output voltage is fixed in the R1514xxxxB and can be selected with a step of 0.1V in the range of 2.0V to 12.0V. The Output voltage accuracy is ±2%.
The packages for this IC are the SOT-89-5 for space saving and the HSOP-6J for higher power applications.
