- Operating/input voltage: 5.5V
- Output Voltage: 3.3V
- Output Current: 500mA
- Operating Temperature: -40℃~+125℃@(Tj)
Application Fit
This exact part is appropriate for designs that require a linear regulator (LDO) with the confirmed package and electrical/function parameters above. Final fit depends on the surrounding circuit, interface, thermal and mechanical requirements of the target design.
Design Considerations
Confirm the available supply rail stays inside the stated operating range, including startup and transient conditions.
Check current, power dissipation and board thermal conditions at the intended operating point rather than using the headline rating alone.
Use the exact SOT-23-5 footprint/package definition when checking PCB land pattern, assembly clearance and sourcing equivalence.
