R1526x-Y Series
3
00 mA, 42 V Voltage Regulator with High Noise Immunity for Industrial Applications
No. EY-527-211022
1
The R1526x is a voltage regulator featuring 300mA output current and 42 V maximum input voltage.
Since this device has excellent noise immunity to external electromagnetic interference, it is suitable for use
in environments where electromagnetic waves may cause malfunctions. This is a high-reliability
semiconductor device for industrial application (-Y) that has passed both the screening at high temperature
and the reliability test with extended hours.
