Key Featrues
Low 175mV Dropout at 500mA: With a low dropout voltage of just 175mV at full load, the MAX1935 maximizes efficiency, especially in low-voltage applications. This feature allows the regulator to maintain stable output even when the input voltage is close to the output voltage, extending battery life in portable devices.
±1.5% Output Voltage Accuracy: The high-accuracy output voltage (±1.5%) ensures precise power regulation, critical for sensitive electronic components. This precision improves the reliability and performance of devices, particularly in applications like wireless base stations and docking stations.
Power-OK Output: The Power-OK feature provides a signal indicating when the output voltage is within regulation, enabling safe and controlled power-up sequences. This is particularly useful in complex systems where timing and sequencing of power supplies are critical.
Thermal-Overload Protection: The built-in thermal-overload protection safeguards the regulator from overheating, enhancing reliability and longevity. This feature is especially important in high-power applications or environments with elevated temperatures, ensuring stable operation and preventing damage to the device.
