Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the specific suffix -T7A indicates tape-and-reel packaging distinct from tube variants. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the fixed 3.3V output aligns with system design needs as adjustable versions exist within the series.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a fixed 3.3V output is required from a 1.8V to 5.5V input source. The 1.2A current rating suits moderate load applications. Consider the TDFN-EP-12 package for thermal performance and space constraints compared to larger packages.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the ISL9110 family of high-efficiency buck-boost regulators. It shares architectural similarities with the ISL9112 but differs in specific feature sets and pin configurations. The manufacturer transitioned from Intersil to Renesas Electronics during product lineage evolution.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
ISL9110IRTNZ serves as the tube-packaged equivalent. ISL9112IRTNZ offers similar topology but may differ in internal control features. Verify pin compatibility and electrical specifications before substituting.
