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

Verify the manufacturer part number ET53112YB against official ETEK Microelectronics documentation to confirm specifications. Ensure the component matches the required 1.2 V output and 300 mA current rating. Check for authenticity through authorized distributors. Confirm package type is 4-DFN (1x1). Do not assume compatibility with other LDO families without cross-referencing datasheets.

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

Select this component when a fixed 1.2 V output is required with moderate current capability. Consider the 1.9 V minimum input voltage constraint relative to the battery or supply source. Evaluate thermal performance based on the 4-DFN package size and expected power dissipation. Compare dropout voltage characteristics if input voltage is close to the output level.
