Description

The MAX8882/MAX8883 dual, low-noise, low-dropout linear regulators operate from a +2.5V to +6.5V input and deliver up to 160mA each of continuous current. Both versions offer low output noise and low dropout of only 72mV at 80mA. Designed with an internal P-channel MOSFET pass transistor, the MAX8882/MAX8883 maintain a low 165µA supply current (both LDOs on), independent of the load current and dropout voltage. Other features include short-circuit protection and thermal-shutdown protection. The MAX8882 has a single shutdown input and provides an external reference bypass pin to improve noise performance. The MAX8883 includes two independent logic-controlled shutdown inputs. The MAX8882/MAX8883 are both available in a miniature 6-pin SOT23 package.
