R1525x Series 200 mA 42 V Ultra Low Supply Current Voltage Regulator
NO. EA-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, this device is suitable for the power source for 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
• Noise Immunity Characteristic Input Voltage Range: 3.5 V to 42.0 V • Maximum Rating: 50 V (Peak Inrush Voltage: 60 V@200ms or less) • Operating Temperature Range: −40°C to 105°C • Supply Current: Typ. 2.2 µA (Typ. 0.1 µA 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
TYPICAL APPLICATIONS
