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

Verify the specific suffix 'BEAJZ' against the manufacturer's latest datasheet to confirm pinout, package dimensions, and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration. Cross-reference the exact quiescent current specification (18µA vs 24µA) as values may vary by source documentation version. Confirm lead times directly with authorized distributors as production cycles are subject to change.

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

Select this component when a wide input voltage range up to 40V is required alongside low static current consumption. The adjustable output feature allows flexibility in setting precise voltage levels between 2.5V and 12V. Consider the 8-SOIC-EP package for surface-mount assembly with exposed pad for thermal dissipation. Verify that the 50mA output current meets the load requirements and that the -40°C to +125°C operating range suits the environmental conditions.

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