Infineon TLE42744 Series Voltage Regulator, 3.3V Output Voltage, 40V Maximum Input Voltage - TLE42744DV33ATMA1

This voltage regulator provides a stable 3.3V output for automotive electronic systems and is intended for PCB mounting in vehicle applications. It delivers regulated power under varying input conditions while conforming to industry component standards for automotive environments.

Features and Benefits:

• Polar design ensures correct output orientation and simplified implementation
• 3.3V output supports low-voltage digital and sensor circuits
• 40V maximum input allows wide transient tolerance
• 15mA quiescent current minimises standby power draw
• TO-252 package enables robust heat dissipation on PCB
• 150°C maximum operating temperature maintains performance in high-heat zones

Applications

• Suitable for control modules in passenger vehicles
• Ideal for sensor power supplies in engine compartments
• Used with infotainment subcircuits requiring stable 3.3V
• Can be used for auxiliary power in commercial vehicles
• Useful for on-board diagnostic and telematics electronics

What mounting method is required for installation?

It is designed for PCB mounting with a TO-252 package footprint.

How does it cope with vehicle electrical transients?

It accepts input voltages up to 40V, providing headroom for common automotive spikes.

What thermal environment can it operate in?

The device is rated to function at temperatures up to 150°C.

How does it affect vehicle standby current consumption?

The regulator draws a quiescent current of 15mA in its idle state.

Is it suitable for use in automotive-grade designs?

It complies with an automotive AEC-Q100-002 specification and meets RoHS requirements.
