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

Verify the specific suffix PR-G corresponds to the SOT-89-5 package type as defined in the ordering information. Confirm the 'H' designator indicates the recommended CE type with pull-down resistor and CL discharge functionality. Ensure environmental compliance matches EU RoHS standards. Cross-reference the nominal output voltage code '17' against the official voltage chart to confirm the 1.7V setting before procurement.

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

Select this variant when a fixed 1.7V output is required with high accuracy. The H-type designation ensures the inclusion of the auto-discharge feature, which is critical for applications requiring fast power-down times. Verify that the application environment stays within the -40°C to 85°C operating range specified for the A-D type series. Ensure sufficient ceramic capacitance is used for phase compensation based on the output voltage requirements.

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

How does the XC6222C171PR-G handle output discharge when disabled?

As an 'H' type device, it features an internal auto-discharge switch that rapidly discharges the electric charge at the output capacitor (CL) to the VSS level when the CE pin receives a low-level signal.

What protection mechanisms are integrated into this regulator?

The device integrates over-current protection, short-circuit protection, and thermal shutdown circuits. These activate when output current exceeds limits or junction temperature reaches 150°C typical.
