The MAX689CSA is a low-dropout linear regulator manufactured by Analog Devices, designed to operate with an input-to-output voltage differential limited only by an external PNP transistor. This specific device offers a fixed output voltage of 3.0V and can support output currents exceeding 1A when paired with appropriate external transistors. Its low dropout voltage, as low as 40mV at 200mA, makes it suitable for battery-powered applications where power efficiency is critical.
The regulator features include output voltage monitoring and shutdown functions. The MAX689CSA has an active-low shutdown control input for turning the output on or off. It operates within a supply range of 2.7V to 11.0V and has a low operating supply current of 150µA, with less than 1µA in shutdown mode. The output accuracy is within ±2%.
Packaged in an 8-SOIC surface-mount package, the MAX689CSA is suitable for various portable instruments, portable telephones, and as a power supply or backup supply for memory. Its design allows for direct driving of an external PNP transistor, simplifying the external component count.
