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

Verify the exact part number S-1317A30-A4T2U4 against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure the HSNT-1010-4 package footprint matches your PCB design. Confirm that the 100 mA load requirement does not exceed the device's thermal limits under your specific ambient conditions. Cross-reference the 1.7 V minimum input voltage with your system's lowest battery state.

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

Select this component when a precise 3 V rail is required with minimal voltage drop across the regulator. The 18 mV dropout makes it suitable for applications where the input voltage is close to the output level, such as single-cell lithium-ion systems near depletion. The 100 mA current capability suits moderate-load digital logic. Consider the HSNT-1010-4 package size constraints during layout planning.

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

This device belongs to the S-1317 series of CMOS LDO regulators from ABLIC. The series is characterized by low quiescent current and high ripple rejection ratios. The S-1317 variant specifically targets general-purpose low-noise applications. The 'A30' suffix indicates the 3.0 V fixed output voltage option. The 'A4T2U4' denotes the specific tape-and-reel packaging and marking configuration.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include other ABLIC S-1317 series parts with different output voltages if voltage adjustment is possible, or similar 100 mA LDOs from other manufacturers with compatible HSNT-4 packages. Verify pin-to-pin compatibility and thermal performance before substitution.
