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

Verify the specific suffix ER-G indicates the USP-6C package type and 3,000 units per reel configuration. Confirm the 'D' designation corresponds to the 85°C maximum operating temperature rating. Ensure compatibility with negative voltage rail requirements and check for RoHS compliance status if required by local regulations.

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

Select this part when a fixed -3.4V negative supply is required with up to 200mA load capability. The USP-6C package is suitable for space-constrained surface mount applications. Consider the dropout voltage characteristics at expected load currents and ensure the input voltage remains within the specified negative range relative to ground.

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

How does the CE pin function affect the output voltage?

When the CE pin receives a high-level signal, the regulator is active. When low or open, it enters stand-by mode, and an internal auto-discharge switch rapidly pulls the -VOUT pin to the VSS level.

What protection mechanisms are included in the XC6901D341ER-G?

The device includes a current limit circuit that activates at the limit current, a foldback short-circuit protection feature, and a thermal shutdown circuit that turns off the driver transistor if the junction temperature exceeds the detection limit.
