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

Verify the specific suffix 'PR-G' confirms the SOT-89-5 package and RoHS compliance. Confirm the 'C' type designation aligns with the required operating temperature range of -40°C to 85°C. Ensure the ordering code matches the exact 2.6V output requirement specified by the design.

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

Select this component for applications requiring a fixed 2.6V rail with up to 700mA capability. The C-type variant is suitable for standard commercial temperature ranges. Verify that the required ceramic output capacitance (4.7µF for 2.1V–2.45V or 2.2µF for higher voltages) meets stability requirements for phase compensation.

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

How does the reverse current protection function?

The IC prohibits reverse current flow from the VOUT pin to the VIN pin when the output voltage is higher than the input voltage, suppressing reverse current to a maximum of 1.5µA.

What is the effect of leaving the CE pin open on the C-type version?

The C/E type includes a pull-down resistor; therefore, if the CE pin is left open, the IC enters the stand-by state and stops operation.
