Design Considerations & Integration Tips

When integrating the MCP1755-3302E/MCVAO into your design, consider these best practices:

• Place input and output ceramic capacitors (1µF minimum recommended) as close as possible to the device pins to ensure stability and optimal transient response
• Utilize the exposed thermal pad for enhanced heat dissipation - connect to ground plane with multiple thermal vias
• The power good output can drive a logic input directly or control external circuitry for power sequencing
• Enable pin allows for controlled startup sequencing and low-power shutdown modes
• For maximum PSRR performance, use low-ESR ceramic capacitors on both input and output
• Consider thermal derating when operating at elevated ambient temperatures to ensure long-term reliability
• Implement proper PCB layout with dedicated ground planes and short trace lengths to minimize noise and voltage drops
