Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '120I' confirms the fixed 1.2V output voltage, as other suffixes indicate different voltages. Ensure the '/MS' designation matches the required 8-MSOP package type. Confirm the 'T' indicates tape and reel packaging if automated assembly is planned. Cross-reference the manufacturer part number against official Microchip documentation to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2V output is required from a 2.7V to 5.5V input source. It is suitable for applications prioritizing low quiescent current and compact size via the MSOP package. Consider alternative models if variable output voltage or higher current capacity is needed. Verify thermal requirements for the specific PCB layout.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MCP1602T family of synchronous buck regulators. The family includes variants with different fixed output voltages, identified by suffixes such as 180I or 330I. These controllers are designed for energy-efficient power management in portable electronics. The technology utilizes current mode PWM for stable regulation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other MCP1602T variants with identical pinouts but different output voltages, such as MCP1602T-180I/MS (1.8V) or MCP1602T-330I/MS (3.3V), provided the system voltage requirement changes. No other manufacturers offer a direct pin-compatible drop-in replacement with identical specifications.
