Линейные регуляторы MAX667EPA+

Фиксированный стабилизатор с малым падением напряжения , 3.5В-16.5В (Vin), 150мВ, 5В/250мА, DIP-8

The MAX667EPA+ is a +5V/programmable low dropout voltage regulator in 8 pin DIP package. The MAX667 low-dropout, positive, linear voltage regulator supplies up to 250mA of output current. With no load, it has a typical quiescent current of 20µA. At 200mA of output current, the input/output voltage differential is typically 150mV. Other features include a low voltage 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-compatible upgrade to the MAX666 in most applications where the input voltages are above +3.5V.
