Maxim MAX1726EUK33-T

Позитив12V20 мА

Overview

The MAX1725/MAX1726EUK33 are ultra-low supply current, low-dropout linear regulators intended for low-power applications that demand the longest possible battery life. Unlike inferior PNP-based designs, the MAX1725/MAX1726s' PMOS pass elements maintain an ultra-low 2μA supply current throughout their entire operating range and in dropout. Despite their ultra-low power consumption, the MAX1725/MAX1726EUK33 have tight output accuracy (1.5%) and require just 1μF output capacitance to achieve good load-transient response. These regulators have a wide input voltage range (+2.5V to +12V), making them excellent choices for systems powered from two lithium-ion (Li+) cells and 9V batteries. Other features include reverse-battery protection, short-circuit protection, and thermal protection. The MAX1725 provides an adjustable 1.5V to 5V output using an external resistor-divider. The MAX1726EUK33 provides factory preset 1.8V, 2.5V, 3.3V, or 5V output voltages (see the Ordering Information in the full data sheet). Both devices are available in a tiny 5-pin SOT23 package.
