SY8009AAAC

Synchronous buck regulator IC delivers up to 1.5 A from a 3 V to 5.5 V input range. The device integrates high-side and low-side MOSFETs with typical on-resistances of 180 mΩ and 120 mΩ, operates at 1.5 MHz, and uses a 0.6 V feedback reference for adjustable output regulation. It supports 100 percent duty-cycle dropout operation, internal soft-start, undervoltage lockout, and thermal shutdown protection. The SOT23-5 package is specified for a -40 °C to 85 °C temperature range and is listed as RoHS compliant and halogen free.
