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

Verify the exact output voltage specification against the official ABLIC datasheet, as suffix variations may indicate different voltage tolerances or package types. Confirm that the TO-92-3 through-hole package aligns with your PCB layout requirements. Ensure the 30 mA output current rating meets the peak load demands of your target application circuit without exceeding thermal limits.

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

Select this component when a fixed 2.3 V output is required with minimal quiescent current draw. The TO-92-3 package is suitable for prototyping or applications where surface-mount space is not constrained. Consider the 320 mV dropout voltage to ensure sufficient input-to-output headroom under maximum load conditions. Verify compatibility with the system's operating temperature range of -40 C to +85 C.

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

The S-812C23AY-B2-U is part of the broader S-812C family of high-voltage CMOS voltage regulators produced by ABLIC Inc. This series is characterized by its ability to operate with high input voltages while maintaining low power consumption. The specific model utilizes a through-hole TO-92-3 package, distinguishing it from surface-mount variants within the same functional family designed for compact electronic assemblies.

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

Direct substitutes include other S-812C series models with identical 2.3 V output and TO-92-3 packaging, such as S-812C23AY-B2-T2U if reel packaging is acceptable. Cross-reference pinouts and electrical characteristics carefully before substituting with LDOs from other manufacturers to ensure compatibility with existing circuit designs.
