- Problem: Output oscillation due to improper compensation
- Solution: Follow manufacturer's compensation network guidelines and verify stability with phase margin analysis
Pitfall 3: EMI/RFI Interference
- Problem: Radiated emissions affecting nearby sensitive circuits
- Solution: Use proper grounding techniques, shielding, and filter components
Pitfall 4: Startup Problems
- Problem: Inrush current causing system reset
- Solution: Implement soft-start circuitry and proper bulk capacitance
### Compatibility Issues with Other Components
Digital Components:
- May require level shifting when interfacing with 1.8V/3.3V logic
