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

Verify the specific product type suffix 'C' to confirm the presence of the pull-down resistor and absence of the discharge shunt function. Ensure the package designation matches HSOP-6 and the environmental code indicates lead-free and halogen-free compliance. Confirm the internal output voltage setting corresponds to the required 2.0 V specification before procurement.

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

Select this component when a fixed 2.0 V output is required with high accuracy. The C-type variant is suitable for designs needing a pull-down resistor but not a discharge shunt function. Ensure input and output ceramic capacitors are at least 2.2 μF to maintain stability. Verify that the thermal dissipation remains within limits for the intended load current.
