MAX882CSA+T

The MAX882CSA+T is a low IQ, low dropout linear regulator in high power (1.5W) 8 pin NSOIC package. It maximizes battery life by combining ultra-low supply currents and low dropout voltages. It has 200mA output current capability at up to +125°C junction temperature. The MAX882 uses P-channel MOSFET pass transistor to maintain low 11μA (15μA maximum) supply current from no load to the full 200mA output. In dropout, the MOSFET does not suffer from excessive base currents that occur when PNP transistors go into saturation. The MAX882 features a 7μA standby mode that disables the output but keeps the reference, low battery comparator and biasing circuitry alive. Applications include pagers, cellular phones, 3.3V and 5V regulators, 1.25V to 11V adjustable regulators, high efficiency linear regulators, battery- powered devices, portable and solar powered instruments.

• Dual mode operation, fixed 3.3V or 1.25V to 11V adjustable output voltage
• Unlike earlier bipolar regulators, no PNP base current losses that increase with output current
• Large input range from 2.7V to 11.5V, operating temperature range from 0°C to +70°C
• Internal 1.1ohm P-channel pass transistor draws no base current
• Low dropout voltage of 320mV at 200mA output current, output noise of 250µVRMS at 10Hz to 10KHz
• Load regulation of 30mV (IOUT = 1mA to 150mA) and line regulation of 10mV
• Foldback current limit of 170mA (VOUT <lt/> 0.8V) and 430mA (VOUT <gt/> 0.8V and VIN - VOUT <gt/> 0.7V)
• Low battery detection comparator, reverse current and thermal overload protection
• 1.25V to 11V Adjustable Regulators; 3.3V and 5V Regulators; Automotive Electronics;
• High-Efficiency Linear Regulators; Pagers and Cell Phones; Portable Instrumentation; Solar-Powered Instruments
