Infineon, Voltage Regulator 40V 7-Pin

This voltage regulator provides stable positive output regulation for electronic systems requiring a regulated supply across a wide input range. Designed as a surface-mounted device, it is intended for industrial and general-purpose power management where compact form factor and thermal endurance are important. The component operates with a low quiescent draw and is suitable for applications that demand dependable regulation from low to high input voltages.

• Wide input range supports 6V to 40V operation, enhancing design flexibility
• Low standby draw of 10μA minimises idle power consumption
• Positive polarity output simplifies system power-rail integration
• Surface-mount package enables automated assembly and compact layouts
• Seven-pin configuration offers sufficient connectivity for control functions
• High maximum operating temperature of 150°C allows elevated thermal margins

• Suitable for industrial control supplies with variable input voltages
• Ideal for auxiliary power rails in machinery and instrumentation
• Used with battery-to-bus conversion modules requiring low quiescent draw
• Can be used for signal-conditioning circuitry needing positive regulation
• Suitable for compact electronic assemblies where SMD mounting is required

Place thermal relief and copper pours adjacent to the device’s pads to aid heat dissipation given its SMD package and elevated temperature capability.

The seven pins permit separate input, output and control or ground connections, enabling discrete routing for sensing, shutdown or adjustment functions.

It is specified to function up to 150°C maximum, allowing operation closer to heat sources or within higher ambient-temperature enclosures.

Designs should handle up to 40V on the input rail and ensure transient suppression above this level to protect the regulator.
