MAX882/MAX883/MAX884 19-0275 Rev 4 7/09 5V/3.3V or Adjustable, Low-Dropout, Low I , 200mA Linear Regulators Q General Description Features The MAX882/MAX883/MAX884 linear regulators maxi- Foldback Current Limiting mize battery life by combining ultra-low supply currents High-Power (1.5W) 8-Pin SO Package and low dropout voltages. They feature 200mA output current capability at up to +125C junction temperature Dual Mode Operation: Fixed or Adjustable and come in a 1.5W SOIC package. The 1.5W package Output from 1.25V to 11V (compared to 0.47W for standard SOIC packages) Large Input Range (2.7V to 11.5V) allows a wider operating range for the input voltage and output current. The MAX882/MAX883/MAX884 use a p- Internal 1.1 p-Channel Pass Transistor channel MOSFET pass transistor to maintain a low 11A Draws No Base Current (15A max) supply current from no-load to the full 200mA output. Unlike earlier bipolar regulators, there are Low 220mV Dropout Voltage at 200mA no PNP base current losses that increase with output Output Current current. In dropout, the MOSFET does not suffer from 11A (typ) Quiescent Current excessive base currents that occur when PNP transistors go into saturation. Typical dropout voltages are 220mV 1A (max) Shutdown Mode or 7A (typ) at 5V and 200mA, or 320mV at 3.3V and 200mA. Standby Mode The MAX882 features a 7A standby mode that disables Low-Battery Detection Comparator the output but keeps the reference, low-battery compara- tor, and biasing circuitry alive. The MAX883/MAX884 fea- Reverse-Current Protection ture a shutdown (OFF) mode that turns off all circuitry, Thermal-Overload Protection reducing supply current to less than 1A. All three devices include a low-battery-detection comparator, fold- Ordering Information back current limiting, reverse-current protection, and thermal-overload protection. PIN- PART TEMP RANGE The output is preset at 3.3V for the MAX882/MAX884 PACKAGE and 5V for the MAX883. In addition, all devices employ MAX882CPA 0C to +70C 8 PDIP Dual Mode operation, allowing user-adjustable outputs from 1.25V to 11V using external resistors. The input volt- MAX882CSA 0C to +70C 8 SO age supply range is 2.7V to 11.5V.
