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

Verify the specific ordering suffix against official documentation to confirm package type (SOT-89-5) and environmental compliance (Lead-free, Sn 100%, halogen-free). Confirm that the product designation matches the required logic level for the ON/OFF pin. Ensure compatibility with the manufacturer's recommended external capacitor specifications for stable operation.

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

Select this component when a fixed 2.4 V output is required with moderate current demands up to 300 mA. Consider the SOT-89-5 package for designs requiring an ON/OFF control pin. Evaluate thermal dissipation constraints as the maximum power dissipation is limited by the package. Ensure the application utilizes capacitors with appropriate ESR values to prevent oscillation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the S-1131 Series of middle output current CMOS voltage regulators. The series offers selectable output voltages from 1.5 V to 5.5 V in 0.1 V steps.
