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).
KEY SPECIFICATIONS CHRACTERISTICS
Input Voltage Range: 3.5 V to 42.0 V Noise Immunity Characteristic Maximum Rating: 50 V (Peak Inrush Voltage: 60 V@200ms or less) Operating Temperature Range: −40°C to 125°C Supply Current: Typ. 2.2 µA (Typ.0.1µA at Standby) Dropout Voltage: Typ. 0.6 V (IOUT = 200 mA, VOUT = 5.0 V) Output Voltage Range: 1.8 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V, 3.4 V, 5.0 V, 5.5 V, 6.0 V, 6.4 V, 7.5 V, 8.0 V, 8.5 V, 9.0 V
