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

Verify the manufacturer source, as Fairchild Semiconductor operations were acquired by ON Semiconductor. Confirm the specific revision level and packaging variant (tape and reel vs. tube) required for your assembly process. Ensure compliance with RoHS directives if applicable to your region. Cross-reference datasheets from both original Fairchild and current ON Semiconductor documentation to confirm pinout and electrical parameter consistency.

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

Select this component when a fixed 2.5V rail is needed with up to 200mA load capacity. It is suitable for designs prioritizing low quiescent current and fast transient response. Compare against other LDO families if higher output currents or adjustable voltage options are required. Ensure the input voltage remains within the 6.5V absolute maximum rating during all operating conditions.
