MAX8882/MAX8883 Dual, Low-Noise, Low-Dropout, 160mA Linear Regulators in SOT23 General Description Features The MAX8882/MAX8883 dual, low-noise, low-dropout Two LDOs in Tiny SOT23 linear regulators operate from a +2.5V to +6.5V input and Up to 160mA Output Current (each LDO) deliver up to 160mA each of continuous current. Both ver- 40V Output Noise (MAX8882) RMS sions offer low output noise and low dropout of only 72mV 72mV Dropout at 80mA Load at 80mA. Designed with an internal P-channel MOSFET Low 165A Operating Supply Current pass transistor, the MAX8882/MAX8883 maintain a low 62dB PSRR (greater than 56dB to 100kHz) 165A supply current (both LDOs on), independent of the load current and dropout voltage. Other features include Independent Low-Power Shutdown Controls short-circuit protection and thermal-shutdown protection. (MAX8883) The MAX8882 has a single shutdown input and provides Thermal-Overload and Short-Circuit Protection an external reference bypass pin to improve noise perfor- Output Current Limit mance. The MAX8883 includes two independent logic- controlled shutdown inputs. The MAX8882/MAX8883 are Selector Guide both available in a miniature 6-pin SOT23 package.
