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

Verify the specific suffix 'MR-G' corresponds to the SOT-25 package and RoHS compliance status before procurement. Confirm that the CE pin logic type 'F' matches the system design requirements for active-high control without pull-down resistors. Ensure the selected component meets the required thermal dissipation limits for the intended PCB layout.

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

Select this component when a fixed 1.8 V rail is required with high current capability up to 300 mA. The F-type designation indicates an active-high enable logic without internal pull-downs, requiring external biasing if the pin state is undetermined. Verify that the input voltage remains above the minimum requirement of 2 V or VOUT plus dropout voltage during operation.
