Infineon Voltage Regulator, 40V Maximum Input Voltage, 2μA Quiescent Current - TLE4251DATMA1


This voltage regulator provides a compact, surface-mounted solution for delivering a stable positive output in electronic systems. Designed for applications requiring a regulated supply across a wide input span, it is housed in a TO-252 package and intended for board-level SMD mounting. The device offers low standby current and is suitable where thermal endurance is necessary.

Features and Benefits:


• Operates from 4V to 40V input for wide-range compatibility
• Positive linear regulation for stable supply voltage control
• Quiescent current of 2μA minimises standby power draw
• Withstands up to 150°C for demanding thermal environments
• Surface mount TO-252 5-pin design simplifies PCB assembly

Applications


• Suitable for industrial control modules with high input voltages
• Ideal for battery-powered equipment requiring low idle draw
• Used with power distribution circuits needing compact regulators
• Can be used for thermally stressed electronics in harsh environments

What mounting considerations are recommended for heat dissipation?


Use adequate copper area on the board to spread heat from the TO-252 pad and apply thermal vias where possible to improve conduction to inner or bottom layers.

How does the pin count affect circuit integration?


The five pins allow separate input, output and ground connections alongside any required sense or adjustment terminals, facilitating straightforward wiring for regulation and stability networks.

What operating limits should designers respect in high-temperature installations?


Ensure the ambient and PCB temperature combined do not lead device case temperatures above 150°C and provide thermal management so junction temperature remains within rated limits.

Are there considerations for signal noise or ripple performance?


Add recommended input and output decoupling capacitors close to the pins to reduce ripple and improve transient response as part of stable linear regulation.
