R1526 Series
High Noise Immunity 42V Input 300mA Voltage Regulator
The R1526 is a voltage regulator featuring 300 mA 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 regulator can be used under high temperature environment. It offers the maximum operating temperature of 105°C for consumer applications, and 125°C for industrial and automotive applications.
- Excellent noise immunity. Refer to Noise Immunity Test in "Technical Documents" tab.
- Pin configuration considering functional safety
