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

Verify the specific suffix PR-G corresponds to the SOT-89-5 package configuration. Confirm that the C series designation aligns with the required CE pin pull-down resistor functionality. Ensure environmental compliance requirements match the Halogen and Antimony-free specifications indicated by the -G suffix.

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

Select this variant when a fixed 3.3V output is required without external output capacitors. The C series type is appropriate if a built-in pull-down resistor on the CE pin is needed to prevent unstable operation when the control pin is left open. Consider the SOT-89-5 package for its specific thermal and footprint characteristics.
