Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix E6T2U corresponds to the HSOP-6 tape packaging format required for your assembly line. Confirm that the D-type designation matches your logic requirements for the ON/OFF pin, as it indicates positive logic control. Ensure environmental compliance specifications align with your manufacturing standards before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5.0 V output is required from a high-voltage source up to 50 V. The D-type variant is appropriate if the system control logic requires a high signal to enable the regulator. Consider the package power dissipation limits when designing for high output currents or elevated ambient temperatures to ensure reliable thermal performance.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the ON/OFF pin function for the S-1142D50H-E6T2U?

As a D-type product, the ON/OFF pin operates with positive logic. Applying a high-level voltage activates the regulator, while a low-level voltage shuts it down to minimize current consumption.

What protection mechanisms are included in this voltage regulator?

The device includes an overcurrent protection circuit to limit output current during short circuits and a thermal shutdown circuit that stops regulation if the junction temperature exceeds approximately 150°C.
