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

Verify the specific package type HSNT-4 (0808) and the D-type function configuration (no discharge shunt or pull-down resistor) against the design requirements. Confirm that the fixed 1.3 V output voltage meets the target load specifications. Ensure input and output capacitor selections comply with the minimum 1.0 μF ceramic capacitor requirement for stability.

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

Select this component when a fixed 1.3 V output is required with low quiescent current consumption. The D-type variant is suitable for applications where discharge shunt and pull-down functions are not needed. Consider the HSNT-4 (0808) package for compact surface-mount designs. Verify that the input voltage remains within the 1.5 V to 5.5 V range under all operating conditions.
