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

Verify the specific suffix E2 to confirm compliance with RoHS directives and halogen-free requirements as stated in the official datasheet. Confirm the TO-252-3 package variant matches the design footprint, distinguishing it from the WFP five-pin version. Ensure the fixed 1 V output aligns with target circuit requirements before procurement.

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

Select this component when a precise 1 V rail is required with moderate current demands up to 500 mA. The TO-252-3 package suits applications needing efficient thermal dissipation in compact spaces. Consider the 2.3 V minimum input voltage constraint to ensure adequate headroom for the desired load current and dropout performance.

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

This part belongs to the BD10KA series of secondary LDO regulators designed for low noise and stability. The series includes various fixed output voltages and package options, such as the TO-252-5 variant.
