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

Verify the specific suffix 'T' indicates compliance with the extended operating temperature range up to 105°C. Confirm the 'PR-G' designation corresponds to the SOT-89-5 package type. Ensure the '-G' suffix confirms RoHS compliance and absence of halogens or antimony. Cross-reference the part number against the manufacturer's latest datasheet to validate availability and pinout configurations before finalizing procurement orders.

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

Select this component when a fixed 3.0V rail is required with moderate current demands up to 300mA. The inclusion of inrush current protection makes it suitable for systems sensitive to power-up transients. The high-speed response and low dropout voltage are advantageous for battery-powered applications where input voltage may fluctuate near the output level. Verify that the required operating temperature range aligns with the extended specification indicated by the designator.

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

What is the function of the CE pin in the XC6223T30BPR-G?

The CE (Chip Enable) pin controls the ON/OFF state of the regulator. A high-level signal activates the output, while a low-level signal enters stand-by mode. In stand-by mode, the internal switch discharges the output capacitor to quickly return VOUT to the VSS level.

How does the inrush current protection work in this regulator?

The built-in inrush current prevention function suppresses the current flowing from VIN to VOUT during startup. It operates when the output voltage is below approximately 30% of the set voltage, limiting the inrush current to a typical value of 150mA for about 120μs to prevent system instability.
