MAX883 Overview
Key Features
- 200mA output current capability at up to +125°C junction temperature and come 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
- 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 MAX882 features a 7µA standby mode that disables the output but keeps the reference, low-battery comparator, and biasing circuitry alive
- The MAX883/MAX884 feature a shutdown (OFF) mode that turns off all circuitry, reducing supply current to less than 1µA
- The output is preset at 3.3V for the MAX882/MAX884 and 5V for the MAX883
- In addition, all devices employ Dual Mode™ operation, allowing user-adjustable outputs from 1.25V to 11V using external resistors
- The input voltage supply range is 2.7V to 11.5V
