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

Verify component obsolescence status before procurement as the device is marked discontinued. Confirm package availability in SOT-23-5 or MLP-6 formats. Ensure design updates account for the lack of new design recommendations. Validate electrical parameters against specific application requirements prior to integration.

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

Select this component only for legacy system maintenance where the 2.5V fixed output matches existing circuit designs. Evaluate alternative regulators for new projects due to discontinuation. Consider thermal resistance characteristics when designing PCB layouts for high-load conditions. Verify compatibility with required output capacitor ESR ranges for loop stability.

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