It is designed to provide a regulated output from 1-cell Li Ion or 2/3-cell NiMH voltages found in handheld portable equipment, 1.6 V to 5.5 V. SiP1759 allows the option of a fixed 3.3-V output voltage, or an adjustable output which can be set from 2.5 V to 5.5 V. The output current is up to 100 mA. For flexibility in application, SiP1759 has a shutdown pin (SD) and an ERROR output to indicate when the output voltage is in regulation. SiP1759 is available in a 10-pin MSOP package and is rated over the industrial temperature range of −40 to 85 _C.
