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

Verify the specific suffix 'DR-G' corresponds to the USP-6B surface-mount package and RoHS compliance status. Confirm that the 'A' designation indicates High Active logic with a pull-down resistor on the CE pin. Ensure the ordering code matches the required 3.2V output specification before finalizing procurement.

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

Select this component when a stable 3.2V rail is required for loads up to 700mA in space-constrained designs. The USP-6B package offers thermal advantages over standard SOT packages. Consider the CE pin functionality if system-level power management shutdown capabilities are necessary for the application design.

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

This part belongs to the XC6210 series of high-speed LDO regulators designed by Torex Semiconductor. The series is characterized by its ability to maintain regulation with minimal input-to-output voltage differential, allowing batteries to be utilized until their voltage drops significantly below the regulated output level.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the logic state required to activate the XC6210A322DR-G?

The 'A' type requires a High (H) signal at the CE pin to activate the regulator. A Low (L) signal or open circuit places the device in standby mode.

How does the current limiter function in this regulator?

The IC features a foldback current limiter. When the load current reaches the limit, the output voltage drops, further reducing the current to protect the device during short-circuit or overload events.
