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

Verify the specific suffix 'IDTF' against official onsemi documentation to confirm exact tape-and-reel specifications and marking codes. Confirm availability status as this part number may be subject to end-of-life notices or discontinuation. Ensure the selected variant matches the required SOT-89 package dimensions and pinout configuration for your PCB design.

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

Select this component when a fixed 5 V supply is required with up to 100 mA load current in a compact surface-mount form factor. Consider the SOT-89 package for thermal performance relative to smaller packages like SOT-223. Verify that the input voltage remains within the 7 V to 30 V range to maintain proper regulation and avoid excessive power dissipation.

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

This regulator belongs to the standard 78L05 family of three-terminal positive voltage regulators. It serves as a direct functional equivalent to other manufacturers' 78L05 devices, such as the UA78L05ACDE4 from Texas Instruments. The KA78L05AIDTF offers similar electrical characteristics but differs in physical packaging and manufacturer-specific testing parameters.

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

Direct substitutes include the UA78L05ACDE4 (Texas Instruments) and MC78L05ACHT1G (onsemi). Verify pin compatibility and thermal resistance values before substitution.
