MAX667
MAX667 is +5V/Programmable Low-Dropout Voltage Regulator manufactured by Maxim Integrated.
Description
The MAX667 low-dropout, positive, linear voltage regulator supplies up to 250m A of output current. With no load, it has a typical quiescent current of 20µA. At 200m A of output current, the input/output voltage differential is typically 150m V. Other features include a lowvoltage detector to indicate power failure, as well as early-warning and low-dropout detectors to indicate an imminent loss of output voltage regulation. A shutdown control disables the output and puts the circuit into a low quiescent-current mode. The MAX667 employs Dual Mode™ operation. One mode uses internally trimmed feedback resistors to produce +5V. In the other mode, the output may be varied from +1.3V to +16V by connecting two external resistors. The MAX667 is a pin-patible upgrade to the MAX666 in most applications where the input voltages are above +3.5V. Choose the MAX667 when high output currents and/or low dropout voltages are desired, as well as for improved performance at higher temperatures.
