MAX8866

The MAX8866 dual, low-dropout linear regulators operate from a +2.5V to +5.5V input range and deliver up to 100mA. At 200mA total load, the PMOS pass transistors keep the supply current at 145A, making these devices ideal for battery-operated portable equipment such as cellular phones, cordless phones, and modems. The features of MAX8866 are as follows: (1)low cost; (2)low, 55mV dropout voltage @ 50mA IOUT; (3)low, 105A no-load supply current; (4)low, 145A operating supply current (even in dropout); (5)low, 350VRMS output noise; (6)independent, low-current shutdown control; (7)thermal overload protection; (8)output current limit; (9)reverse battery protection; (10)dual mode operation: fixed or adjustable (1.25V to 5.5V)outputs.

The absolute maximum ratings of the MAX8866 are: (1)VIN to GND: -6V to +6V; (2)output short-circuit duration: infinite; (3)SET_ to GND: -0.3V to +6V; (4)SHDN_ to GND: -6V to +6V; (5)SHDN_ to IN: -6V to +0.3V; (6)OUT_ to GND: -0.3V to (VIN + 0.3V); (7)continuous power dissipation (TA = +70°C) MAX (derate 4.1mW/°C above +70°C): 330mW; (8)operating temperature range: -40°C to +85°C; (9)junction temperature: +150°C; (10)thermal resistance (qJA): 244°C/W; (11)storage temperature range: -65°C to +160°C; (12)lead temperature (soldering, 10sec): +300°C.
