Key Featrues
Preset or Adjustable Output Voltage: The MAX6329/MAX6349 offers preset output voltages of +3.3V, +2.5V, or +1.8V, as well as an adjustable output option. This flexibility allows the device to cater to a wide range of applications, ensuring compatibility with various microprocessors and low-power devices, enhancing its versatility in portable and battery-powered equipment.
Low Dropout Voltage (180mV at 100mA): With a low dropout voltage of just 180mV at 100mA load, the regulator maintains stable output even when the input voltage is close to the output voltage. This feature is crucial for extending battery life in portable devices, as it allows the device to operate efficiently even as the battery voltage drops.
Integrated Microprocessor Reset Circuit: The built-in reset circuit with a 100ms (min) timeout ensures reliable operation of connected microprocessors by providing a controlled reset signal during power-up or voltage fluctuations. This feature enhances system reliability and reduces the need for external reset circuitry, simplifying design and saving board space.
Low Quiescent Current (25µA): The device consumes only 25µA of supply current, independent of the load. This ultra-low quiescent current makes it ideal for battery-powered applications, significantly improving energy efficiency and extending battery life in portable devices like PDAs, GPS systems, and handheld instruments.
Thermal and Short-Circuit Protection: The MAX6329/MAX6349 includes built-in protection against over-temperature and short-circuit conditions. These safety features ensure the device operates reliably under adverse conditions, preventing damage to the regulator and connected components, thereby improving system durability and reducing maintenance costs.
