Infineon, Voltage Regulator 40V TO-252 5-Pin

This voltage regulator provides stable positive output voltage regulation for electronic circuits, designed for surface-mount assembly in compact equipment. It is intended to manage input voltages as high as 40V while operating from supplies down to 3.5V, and is specified for use at elevated temperatures up to 150°C. The device is supplied in a TO-252 package and offers a low quiescent current characteristic suitable for low-power designs.

• 40V maximum input enables high-voltage supply tolerance
• 3.5V minimum input supports low-voltage operation
• 150 μA quiescent current minimises standby power drain
• 150°C maximum operating temperature allows hot environments
• Positive polarity simplifies integration into common rails
• 5 pins in TO-252 package permit robust electrical connections

• Suitable for industrial control electronics requiring 40V tolerance
• Ideal for battery-powered systems needing low standby current
• Used with power assemblies exposed to high ambient temperatures
• Can be used for compact SMD modules where board space is limited
• Suitable for devices requiring positive rail regulation in small form factors

It is intended for surface-mount placement and soldering to PCB pads compatible with TO-252 footprints.

The 5-pin arrangement separates input, output and control/ground functions to simplify connection and thermal routing on the board.

The device is not specified to automotive standards, so it is not intended for certified automotive use.

Expect to manage heat dissipation through copper planes and thermal vias since the device is rated to work up to a 150°C maximum operating temperature.
