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

Verify the specific part number against official manufacturer documentation to confirm the exact output voltage and package configuration. Ensure that the ordering suffix matches the required tape and reel specifications. Confirm compliance with RoHS and halogen-free requirements as stated in the datasheet before finalizing procurement orders.

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

Select this component when a fixed 8.0 V output is required from a high-voltage input source. Consider the HSOP-6 package for high-density mounting needs. Evaluate the power dissipation limits relative to the expected load current and ambient temperature to ensure safe operation within the specified junction temperature range.

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

This device belongs to the S-1142A/B Series of low dropout CMOS voltage regulators. The series is characterized by its ability to operate at high input voltages while maintaining low quiescent current. The 'B' designation indicates positive logic for the ON/OFF pin, distinguishing it from the 'A' type which uses negative logic.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

For applications sensitive to output voltage overshoot during power-on, consider the S-1142C/D Series as an alternative. Verify that any substitute maintains the same output voltage, current capacity, and package dimensions.
