MAX8882/MAX8883 Dual, Low-Noise, Low-Dropout, 160mA Linear Regulators in SOT23 General Description Features 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 logiccontrolled shutdown inputs. The MAX8882/MAX8883 are both available in a miniature 6-pin SOT23 package. ●● ●● ●● ●● ●● ●● ●● 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) ●● Thermal-Overload and Short-Circuit Protection ●● Output Current Limit Selector Guide PART Applications ●● μP/DSP Core/IO Power ●● Cellular and PCS Telephones ●● PDAs and Palmtop Computers ●● Notebook Computers ●● Digital Cameras ●● Hand-Held Instruments Ordering Information SHUTDOWN TEMP RANGE PINPACKAGE MAX8882EUT_ _* Single -40°C to +85°C 6 SOT23-6 MAX8883EUT_ _* Dual -40°C to +85°C 6 SOT23-6 PART V OUTA V OUTB TOP MARK 2.85 AANR MAX8882EUTAQ 3.3 2.5 AAPW MAX8882EUTA5 3.3 1.8 AARY MAX8882XEUTA5 3.3 N.C.

Bypass with a low-leakage 0.01μF ceramic capacitor for reduced noise at both outputs. SHDNA Shutdown A Input. A logic low shuts down regulator A. If SHDNA and SHDNB are both low, both regulators and the reference turn off, and supply current is reduced to 10nA. If either SHDNA or SHDNB is a logic high, the reference is on. Connect to IN for normal operation. Shutdown B Input. A logic low shuts down regulator B. If SHDNA and SHDNB are both low, both regulators and the reference turn off, and supply current is reduced to 10nA. If either SHDNA or SHDNB is a logic high, the reference is on.
