Product Summary

The MAX883ESA-T linear regulator maximizes battery life by combining ultra-low supply currents and low dropout voltages. The MAX883ESA-T features 200mA output current capability at up to +125℃ junction temperature and comes in a 1.5W SOIC package. The 1.5W package (compared to 0.47W for standard SOIC packages) allows a wider operating range for the input voltage and output current. The MAX883ESA-T uses a Pchannel MOSFET pass transistor to maintain a low 11μA (15μA max) supply current from no-load to the full 200mA output. Unlike earlier bipolar regulators, there are no PNP base current losses that increase with output current. And, in dropout, the MOSFET does not suffer from excessive base currents that occur when PNP transistors go into saturation. Typical dropout voltages are 220mV at 5V and 200mA, or 320mV at 3.3V and 200mA. The applications of the MAX883ESA-T include: Pagers and Cellular Phones, 3.3V and 5V Regulators, 1.25V to 11V Adjustable Regulators, High-Efficiency Linear Regulators, Battery-Powered Devices, Portable Instruments, Solar-Powered Instruments.
