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

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pin configuration and environmental codes. Confirm that the selected variant matches the required ON/OFF logic type (positive or negative) for the target application design. Ensure compliance with RoHS and halogen-free requirements as specified in the product name structure section of the datasheet.

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

Select this component when a fixed 4.8 V output is required with high accuracy and low quiescent current. Consider the S-1121 series if a different pin configuration is needed for the same electrical performance. Evaluate the output capacitor ESR requirements carefully, as stable operation depends on utilizing capacitors within the optimal resistance range to prevent oscillation.
