MAX882 - 5V/3.3V or Adjustable / Low-Dropout / Low IQ / 200mA Linear Regulators

General Description

The MAX882/MAX883/MAX884 linear regulators maximize battery life by combining ultra-low supply currents and low dropout voltages.

They feature 200mA output current capability at up to +125°C junction temperature and come in a 1.5W SOIC package.

Key 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. All three devices include a low-battery-detection comparator, foldback current limiting, reverse-current protection, and thermal overload protection. The output is preset at 3.3V for the MAX882/MAX884 and 5V for the MAX883. In addition, all devices employ Du.

19-0275; Rev 0; 12/94 5V/3.3V or Adjustable, Low-Dropout, Low IQ, 200mA Linear Regulators _______________General Description The MAX882/MAX883/MAX884 linear regulators maximize battery life by combining ultra-low supply currents and low dropout voltages. They feature 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. The MAX882/MAX883/MAX884 use 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.
