Overview
The MAX5008CUB+ is a charge pump voltage regulator manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 2.95V to 5.5V and provides a regulated 5V output. The device delivers an output current up to 125mA. Key electrical parameters include a switching frequency of 1MHz, a quiescent current of 0.1μA in shutdown mode, and operation within a temperature range of 0°C to +70°C. It utilizes a 10-pin μMAX package.
Feature Summary
- Integrated short-circuit protection for enhanced reliability
- Configurable output current limiting capability
- Shutdown control minimizes power consumption
- Fault signal output for over-current or over-voltage conditions
Applications
- Flash memory power supplies
- Battery-powered systems
- 3V to 5V voltage conversion circuits
Procurement Notes
Verify the specific suffix 'CUB+' against official datasheets to confirm package type and temperature grade. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure compatibility with existing PCB footprint for the 10-pin μMAX package during integration.
Selection Notes
Select this component when a compact solution is required for stepping up low input voltages to a stable 5V rail. Consider the 1MHz switching frequency for minimizing external passive component size. Evaluate the need for fault signaling and current limiting features inherent to this design for system protection.
Part Context
This part belongs to the Maxim Integrated charge pump regulator family, designed for space-constrained applications. It serves as a standalone voltage converter without requiring inductors, relying instead on capacitors for energy transfer. The μMAX package allows for high-density board layouts.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer updated packaging or extended temperature ranges. Verify functional equivalence regarding switching frequency and output regulation before substitution.
