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

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct output voltage, package type, and tape/reel specifications. Confirm RoHS compliance status and environmental declarations prior to ordering. Cross-reference the manufacturer part number with distributor codes to prevent substitution errors during procurement.

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

Select this component when a fixed 1.4 V output is required with high precision. Ensure the application load does not exceed the 50 mA limit. Verify that the input voltage remains within the 10 V maximum rating. Consider the SC-82AB-4 package dimensions for PCB layout constraints. Compare operating current requirements against other LDO options if ultra-low standby power is critical.
