ILC7280AR3030X

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ILC7280AR3030X is a micropower dual low-dropout (LDO) regulator manufactured by Fairchild Semiconductor. It integrates two independent 150mA CMOS LDO channels within an MSOP-8 package. The device provides fixed output voltages of 3.0V for both channels. Key electrical specifications include a maximum input voltage of 9V and a minimum operating voltage of 2.98V. The typical dropout voltage is 155mV, with a maximum of 180mV at full load. The unit features a line regulation of 0.014% and operates across a temperature range from -65°C to +150°C junction temperature.

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

Verify the manufacturer origin as Fairchild Semiconductor or its successor onsemi, noting potential brand transitions. Confirm the specific suffix 'X' indicates the correct tape-and-reel packaging variant. Ensure compliance with RoHS directives if required, as some legacy versions may not be certified. Cross-reference the exact part number against current distributor catalogs to confirm availability status and lead times.

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

Select this component when dual isolated 3.0V rails are required from a single input source up to 9V. The 150mA output current per channel suits moderate load applications. Consider the MSOP-8 package size for space-constrained PCB layouts. Evaluate the thermal performance given the wide operating temperature range. Compare dropout voltage requirements against other LDOs if input voltage headroom is minimal.
