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

Verify the specific product type suffix (D) to confirm the absence of discharge shunt and pull-down functions. Ensure the package designation matches SC-82AB requirements. Confirm environmental compliance codes align with lead-free and halogen-free specifications. Cross-reference the exact output voltage code to ensure compatibility with system design constraints.

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

Select this component when a fixed 1.9 V output is required with minimal quiescent current. Verify that the application does not require the discharge shunt or constant current source pull-down features, as these are excluded in the D-type configuration. Ensure input and output capacitors meet the minimum capacitance requirements for stability.
