MAX5008CUB+T

Overview

The MAX5008CUB+T is a charge pump voltage regulator manufactured by Analog Devices Inc. (Maxim Integrated). It operates with an input voltage range of 2.95 V to 5.5 V and provides a fixed regulated output of 5 V. The device supports an output current up to 125 mA. Key electrical characteristics include a switching frequency of 1 MHz, which allows for the use of small surface-mount ceramic capacitors. The component includes integrated protection features such as short-circuit protection, thermal shutdown, and over-current limiting. It functions within a specified operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated short-circuit protection and thermal shutdown capabilities
• Configurable output current limit via external resistor
• Low standby current consumption in shutdown mode
• Fault signal output for over-current or over-voltage conditions

Applications

• Flash memory power supplies
• Battery-powered systems requiring voltage step-up
• 3V to 5V voltage conversion circuits

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade variant when sourcing. Confirm the '+T' designation corresponds to tape-and-reel packaging requirements for your assembly line. Cross-reference the manufacturer's latest datasheet to ensure compliance with current RoHS directives and material declarations before finalizing procurement orders.

Selection Notes

Select this component when a compact solution is required for stepping up low input voltages to a stable 5V rail. The high switching frequency minimizes passive component size. Ensure the application load does not exceed the 125 mA limit without adjusting the external current-limiting resistor. Verify that the input source can sustain the peak currents drawn during regulation cycles.

Part Context

This part belongs to the Maxim Integrated MAX5008 family of charge pump regulators. These devices are designed for applications needing efficient voltage conversion from single-cell lithium-ion or alkaline batteries. The UMAX-10 package offers a small footprint suitable for space-constrained portable electronics and embedded control systems.
