R1525x Series
200 mA 42 V Ultra Low Supply Current
Voltage Regulator for Automotive Applications
NO. EC-520-190109
OVERVIEW
The R1525x is a low supply current
voltage regulator featuring 200mA output current and up to 42 V input
voltage. By providing excellent noise immunity to externally generated RF noise, this device is suitable for the automotive power source for car accessories and control unit used under the electromagnetic environment.
KEY BENEFITS
Achieves low-supply current of 2.2µA (Typ.) with the LDO at maximum rating 50 V (Peak Inrush
Voltage:
60 V).
Ensures the design margin by the output
voltage with high-accuracy of ±0.6% (Ta=25°C). Protects the output
voltage variations in high-frequency noise band (10MHz to 1GHz).
