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

Verify the specific ordering suffix DR-G confirms the USP-6B surface-mount package and Halogen/Antimony-free compliance. Ensure the A-series designation matches the requirement for High Active logic with an internal pull-down resistor on the Control Enable pin. Confirm the second decimal digit '9' corresponds to the required 1.9V output voltage setting before finalizing procurement specifications.

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

Select this component when a fixed 1.9V rail is required with high current capability up to 700mA. The A-type configuration is suitable for systems requiring active-high enable signals with default shutdown states via the internal pull-down resistor. Verify that the application load does not exceed the thermal dissipation limits of the USP-6B package under maximum ambient temperature conditions.

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

What is the logic state of the CE pin for the XC6210A series?

The XC6210A series features a High Active CE pin with an internal pull-down resistor. The regulator turns ON when the CE pin voltage is high (VIN) and enters stand-by mode when the CE pin is low (VSS).

How does the current limiter operate in this regulator?

The IC includes a fixed current limiter circuit and a foldback circuit. When the output current reaches the limit level, the output voltage drops, triggering the foldback circuit to further reduce the output current and protect the device during overload or short-circuit conditions.
