MAXIM INTEGRATED / ANALOG DEVICES MAX1857EUA47 Low-Dropout Voltage Regulator

The MAX1857EUA47+ is a low-dropout linear regulator in an 8-pin µMAX package, capable of delivering up to 500mA. It features a low dropout voltage of 120mV and provides a high-accuracy output voltage set internally at 4.75V or adjustable from 1.25V to 5.0V via an external resistor divider. The device includes an internal PMOS pass transistor enabling a low supply current of approximately 135µA, which remains independent of load, making it ideal for portable battery-powered devices such as PDAs, cellular phones, cordless phones, base stations, and laptops. Additional features include an active-low open-drain reset output with a 4.5ms timeout, a shutdown mode consuming only 0.1µA, short-circuit protection, and thermal shutdown protection. The supply voltage range is 2.5V to 5.5V, with an operating temperature range from -40°C to 85°C. Applications primarily involve power management in portable devices.
