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

Verify the specific ordering suffix PR-G confirms the SOT-89-5 package configuration and standard reel quantity. Ensure the CE pin is properly biased to either VIN or VSS to maintain stable operation, as leaving it open may cause undefined behavior. Confirm compliance requirements such as RoHS status if applicable to your manufacturing process.

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

Select this part when a fixed 2.2V rail is required from inputs up to 28V with high accuracy. The A-series designation ensures suitability for extended temperature environments up to 105°C. Consider the SOT-89-5 package for its balance of thermal dissipation and footprint size compared to smaller alternatives.

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

What happens if the CE pin is left open?

Leaving the CE pin open results in undefined operation. For stable performance, the CE pin must be connected to either the VIN voltage or the VSS ground.

How does the short circuit protection work?

The IC features a current fold-back circuit. When the load current reaches the limit level, the output voltage drops, reducing the output current to approximately 30mA during a short circuit condition.
