MAX5005/MAX5006/MAX5007 are low-dropout (LDO), micropower linear voltage regulators with an integrated microprocessor (µP) reset circuit for use with USB peripheral devices. Each device is available with a fixed +3.3V output voltage and can deliver up to 150mA load current. Each device features ±15kV transient voltage suppression (TVS) as well as precision 1.5kΩ data-line termination resistors for USB digital signals making them ideal for use with USB peripherals. The MAX5005/MAX5006/MAX5007 include an internal reset circuit that enables the USB microcontroller 100ms after the LDO regulator output voltage reaches regulation. Reset outputs are available in push-pull (active-low or active-high) and open-drain (active-low) options. The MAX5005/MAX5006/MAX5007 are optimized for use with a 1µF ceramic output capacitor. Each device includes thermal shutdown protection, output short-circuit protection, and output to input reverse leakage protection. These devices also include an active-low manual reset input. The MAX5005 features an open-drain reset output, the MAX5006 features an active-low push-pull reset output, and the MAX5007 features an active-high push-pull reset output. Each device is available in a space-saving 10-pin µMAX package.
The MAX5005, MAX5006, and MAX5007 are low‑dropout, micropower linear voltage regulators designed for USB peripheral devices. Each part provides a fixed 3.3 V output, up to 150 mA load current, and includes an integrated microprocessor reset circuit that asserts after the output reaches regulation.
Key features include +15 kV transient‑voltage‑suppression (TVS) on the D+ and D‑ data lines, selectable 1.5 kΩ termination resistors, thermal shutdown, short‑circuit protection, and reverse‑leakage protection. The devices are supplied in a compact 10‑pin uMAX package and are optimized for use with a 1 pF ceramic output capacitor, though larger capacitors improve stability and noise performance.
