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

Verify the specific suffix 'PR-G' corresponds to the SOT-89-5 package and RoHS compliance status. Confirm that the 'A' type designation matches the required CE High Active logic with pull-down resistor configuration. Ensure the ordering code aligns with the 1.7V output specification before finalizing procurement.

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

Select this component when a fixed 1.7V rail is required with high current capability up to 700mA. The A-type series is appropriate if active-high enable control with an internal pull-down resistor is desired. Verify that the application load does not exceed the thermal dissipation limits for the SOT-89-5 package under expected ambient conditions.

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

What is the behavior of the CE pin when left open?

For the XC6210A series, the CE pin has an internal pull-down resistor. An open state results in a Low signal, placing the IC in standby mode.

How does the current limiter protect the output?

The device utilizes a foldback current limiter. When the output current reaches the limit, the output voltage drops further, reducing the output current to protect the pin during overload or short-circuit conditions.
