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

Verify the specific ordering suffix MR-G confirms the SOT-25 package configuration and reel quantity. Ensure the A-series designation matches requirements regarding the absence of CE pull-down resistors and output capacitor discharge features. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

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

Select this component when a fixed 1.7 V rail is required with minimal supply current consumption. The SOT-25 package offers a compact footprint suitable for space-constrained designs. Consider the A-series variant if external capacitor discharge during shutdown is not necessary, as it simplifies the control logic interface compared to the B-series.
