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

Verify the specific output voltage code '37' corresponds to 3.7 V in the official ABLIC product name list. Confirm the 'A' suffix indicates negative logic for the ON/OFF pin. Ensure the E6T2 packing specification matches your assembly requirements. Contact ABLIC directly for automotive or medical equipment usage validation as required by the datasheet caution.

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

Select this component when a fixed 3.7 V output is required with high input voltage tolerance up to 50 V. The negative logic ON/OFF pin configuration suits systems where a low signal enables regulation. Verify that the application load does not exceed the 200 mA limit while respecting package power dissipation constraints. Ensure ceramic capacitors of at least 0.1 µF are used 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 LDO regulators. The 'A' designation specifies negative logic control for the ON/OFF pin, distinguishing it from the 'B' series which uses positive logic. The 'H' suffix denotes the extended temperature range up to +105°C, suitable for automotive and industrial environments.

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 recommended by the manufacturer. Direct substitutes with identical pinouts and specifications should be sourced from ABLIC's official product lineup.
