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

Verify the specific output voltage code '86' corresponds to 8.0 V as per the naming convention. Confirm the 'B' suffix indicates positive logic for the ON/OFF pin. Ensure the E6T2 package designation matches the required HSOP-6 tape and reel specifications. Check for automotive or medical application requirements which may necessitate direct contact with ABLIC Inc. prior to use.

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 up to 50 V. The B-type designation is suitable for systems requiring positive logic control on the ON/OFF pin. Consider the thermal dissipation limits of the HSOP-6 package if operating near the maximum output current of 200 mA. Ensure input and output capacitors meet the minimum 0.1 µF ceramic requirement for stability.

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

This part belongs to the S-1142A/BxxH Series of high-withstand voltage low dropout regulators. The series is characterized by its ability to operate at high temperatures up to 105°C and its low quiescent current. The 'B' variant specifically defines the logic polarity of the enable pin, distinguishing it from the 'A' variant 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/DxxH Series as an alternative. Verify that any substitute maintains the same HSOP-6 package footprint and pin configuration to ensure mechanical compatibility.
