R1515x Series
AEC-Q100 Grade 2 Compliant
50 mA Voltage Regulator (Wide Input Voltage Range) for Automotive Applications
NO. EC-153-150701
OUTLINE
The R1515x series are CMOS-based positive voltage regulator (VR) ICs featuring 50mA output current. The
R1515xxxxB has features of high input voltage and ultra-low supply current. A peak current limit circuit, a short
current limit circuit, and a thermal shutdown circuit are built in the R1515x series.
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.
The regulator output voltage is fixed in the R1515xxxxB and can be selected with a step of 0.1V in the range
of 2.0V to 12.0V. Output voltage accuracy is ±2%.
The packages for these ICs are the SOT-89-5 for space saving and the HSOP-6J for higher power applications.
