MAX1725-12V, Ultralow IQ, Low Dropout Linear Regulator
Overview
The MAX1725/MAX1726 are ultra-low supply current, low-power, low-dropout linear regulators for applications requiring longest battery life. Unlike shoddy PNP-based designs, the MAX1725/MAX1726s' PMOS bypass elements maintain an ultra-low 2µA supply present over their entire operating range and drop out. Despite their ultra-low power consumption, the MAX1725/MAX1726 feature tight output accuracy (1.5% ), and require just 1µF of output capacitance to achieve good load transient response. These regulators have a wide input voltage range (2.5 V to +12 V), making them an excellent choice from two lithium-ion (Li+ battery) battery and 9V powered system battery. Additional 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 MAX1726 provides factory presets 1.8V, 2.5V, 3.3V or 5V output voltage (see ordering information). Both devices are available in a tiny 5-pin SOT23 package.
