Dual, Low-Noise, Low-Dropout, 160mA Linear Regulators in SOT23
General 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 Pchannel
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. o o o o o o o
