R1501x Series
1A 24V Input VR
No.EK-184-091101
CMOS Voltage Regulator
The R1501x Series are CMOS-based voltage regulators featuring 1A output current and 24V input voltage. The R1501x series
provides high input voltage operation and low on-resistance (at VOUT = 10V, below 0.6
Ω) because of using CMOS transistor. In addition
to a fold-back protection circuit built into conventional regulators, R1501x 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 24V, the R1501x series are
very suitable for power source of car accessories.
