MAX5008 5V Regulated 5V USB Charge Pump with Programmable Current Limit
The MAX5008 is a charge‑pump regulator that provides a regulated 5 V output from a 2.95 V to 5.5 V input. It delivers up to 125 mA load current and includes an adjustable over‑current protection and a fault output indicator. The device operates at a high 1 MHz switching frequency, allowing the use of small surface‑mount ceramic capacitors, and features a low‑power shutdown mode that reduces supply current to less than 0.1 µA.
Key features include a 10‑pin uMAX package (1.4 mm high), thermal shutdown at 150 °C with 30 °C hysteresis, and a programmable current limit set by an external resistor. Typical applications are flash‑memory supplies, USB host devices, and battery‑powered systems requiring 3.3 V to 5 V local conversion.
| Input Voltage Range | 2.95 V to 5.5 V |

The MAX5008 operates with an input voltage from 2.95 V to 5.5 V.
It can supply a regulated 5 V output up to 125 mA.
Yes, driving the SHDN pin low puts the device in shutdown mode, reducing supply current to less than 0.1 µA and placing the output in a high‑impedance state.
It is offered in a 10‑pin uMAX package that is 1.4 mm high.
