MAX1725EUK-T

12V ，超低IQ，低压差线性稳压器 12V, Ultra-Low IQ, Low-Dropout Linear Regulators

General Description

The MAX1725/MAX1726 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/MAX1726 have tight output accuracy 1.5% and require just 1µF output capacitance to achieve good load-transient response.
