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

Verify the specific package type SOT-89-5 and the active-high logic level of the CE pin, as standard Type B devices lack internal pull-down resistors. Confirm that the ordering suffix PR-G indicates compliance with EU RoHS standards and is free from halogen and antimony. Ensure the selected component matches the required 3.1V output voltage tolerance of ±2% for your application design.

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

Select this component when a fixed 3.1V rail is required with minimal quiescent current draw. The Type B designation indicates an active-high control logic without built-in pull-down resistors, necessitating external drive or biasing to prevent unstable states. Consider the thermal dissipation capabilities of the SOT-89-5 package relative to the expected load current and input-output differential.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the XC6209 series of high-speed LDO regulators designed for portable electronic applications. The series utilizes CMOS technology to achieve low noise and high precision. The XC6209B variant specifically offers 150mA output capability with active-high CE control, distinguishing it from other types in the family that may feature different current ratings or logic polarities.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Substitutes must match the 3.1V fixed output, 150mA current rating, and SOT-89-5 package. Verify compatibility with the active-high CE logic and ensure equivalent dropout voltage and ripple rejection specifications are met for direct replacement in existing designs.
