MAX8882/MAX8883 Dual, Low-Noise, Low-Dropout, 160mA Linear Regulators in SOT23 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. µP/DSP Core/IO Power Cellular and PCS Telephones PDAs and Palmtop Computers Notebook Computers Digital Cameras Hand-Held Instruments Pin Configurations TOP VIEW OUTB 1 6 OUTA MAX8882 GND 2 4 SHDN o Two LDOs in Tiny SOT23 o Up to 160mA Output Current each LDO o 40µVRMS Output Noise MAX8882 o 72mV Dropout at 80mA Load o Low 165µA Operating Supply Current o 62dB PSRR greater than 56dB to 100kHz o Independent Low-Power Shutdown Controls MAX8883 o Thermal-Overload and Short-Circuit Protection o Output Current Limit Selector Guide PART MAX8882EUTJJ VOUTA VOUTB TOP MARK AANR MAX8882EUTAQ AAPW MAX8882EUTA5 AARY MAX8882EUTQ5 AAPX MAX8882EUTGG AAZT MAX8883EUTJJ AANS MAX8883EUTAQ AAPY MAX8883EUTA5 AARZ MAX8883EUTQ5 AAPZ MAX8883EUTGG AAZU Ordering Information PART SH UTDO WN TEMP RANGE PINPACKAGE MAX8882EUT_ _* Single -40°C to +85°C 6 SOT23-6 MAX8883EUT_ _* Dual -40°C to +85°C 6 SOT23-6 *See Selector Guide Typical Operating Circuit SOT23-6 Pin Configurations continued at end of data sheet.
