MAX8882

19-1818; Rev 1; 10/01 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 Features Two LDOs in Tiny SOT23 Up to 160mA Output Current (each LDO) 40µVRMS Output Noise (MAX8882) 72mV Dropout at 80mA Load Low 165µA Operating Supply Current 62dB PSRR (greater than 56dB to 100kHz) Independent Low-Power Shutdown Controls (MAX8883) o Thermal-Overload and Short-Circuit Protection o Output Current Limit MAX8882/MAX8883 Selector Guide PART MAX8882EUTJJ MAX8882EUTAQ MAX8882EUTA5 MAX8882EUTQ5 MAX8882EUTGG MAX8883EUTJJ MAX8883EUTAQ MAX8883EUTA5 MAX8883EUTQ5 MAX8883EUTGG VOUTA 2.85 3.3 3.3 2.5 3.0 2.85 3.3 3.3 2.5 3.0 VOUTB 2.85 2.5 1.8 1.8 3.0 2.85 2.5 1.8 1.8 3.0 TOP MARK AANR AAPW AARY AAPX AAZT ...
