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

Verify the exact suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure the TO-92-3 package variant matches your PCB footprint requirements. Cross-reference the specific batch date codes with manufacturer reliability data if long-term deployment is planned. Confirm RoHS compliance status for your target market regulations before finalizing procurement orders.

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

Select this component when a fixed 4.1 V output is required with high input voltage capability up to 16 V. The TO-92-3 package is suitable for through-hole mounting where space constraints are less critical than robust mechanical stability. Consider the 65 mA output limit for load requirements and verify that the 2% accuracy meets system tolerance specifications. Evaluate thermal dissipation needs based on the expected voltage drop and load current.

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

This part belongs to the S-812C series of LDO regulators from ABLIC, designed for low-power applications. The series typically includes various output voltages and package options.
