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

Verify the specific suffix 'MR-G' corresponds to the SOT-25 package configuration required for your design. Confirm the 'A' designation indicates the absence of an internal CE pin pull-down resistor, which necessitates external biasing if the pin state must be defined during power-up. Ensure the component meets RoHS compliance standards for your manufacturing process.

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

Select this variant when a fixed 2.6V rail is required in a compact SOT-25 footprint. The 'A' type is suitable for applications where the system controller actively manages the enable signal without relying on internal pull-down resistors. Verify that the external ceramic output capacitor value meets the phase compensation requirements specified in the datasheet for stable operation at the 2.6V setting.
