Overview The MAX667 low-dropout, positive, linear regulator delivers up to 250mA of output current. With NO load, it has a typical quiescent current of 20µA. At 200mA output current, the input/output voltage difference 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 impending ...

The LT1117 is an active low dropout regulator designed to deliver up to 800mA of output current. The device is available in adjustable and fixed output voltages of 2.85V, 3.3V and 5V. The 2.85V version was designed specifically to use an actively terminated SCSI bus. All internal circuits are designed to operate down to 1V differential input to output. Guaranteed voltage differenc...

The ADM660/ADM8660 charge pump voltage converters can be used to invert the input voltage to VOUT = VIN or dual (ADM660 only) to VOUT = 2" VIN. Input voltages ranging from +1.5 V to +7 V can be inverted to -1.5 V to -7 V output supply. This inverting scheme is ideal for single supply generating a negative rail system. Only two small external capacitors are required f...
