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

Verify the specific part number against official ABLIC documentation to confirm the exact output voltage and package configuration. Ensure that the application environment respects the absolute maximum ratings, particularly regarding input voltage limits and power dissipation constraints on the HSOP-6 package. Confirm RoHS compliance requirements if applicable to your manufacturing process.

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

Select this component when a high input voltage capability up to 50 V is required alongside low quiescent current consumption. The B-type designation indicates positive logic for the ON/OFF pin, which must be considered in system design. Evaluate the dropout voltage characteristics relative to the expected load current to ensure stable regulation under minimum input voltage conditions.
