Description
General part information
MAX889 Series
The MAX889 inverting charge pump delivers a regulated negative output voltage at loads of up to 200mA. The device operates with inputs from 2.7V to 5.5V to produce an adjustable, regulated output from -2.5V to -VIN.The MAX889 is available with an operating frequency of 2MHz (T version), 1MHz (S version), or 0.5MHz (R version). The higher switching frequency devices allow the use of smaller capacitors for space-limited applications. The lower frequency devices have lower quiescent current.The MAX889 also features a 0.1µA logic-controlled shutdown mode and is available in an 8-pin SO package. An evaluation kit, MAX889SEVKIT, is available.ApplicationsBattery-Powered ApplicationsCamcordersDigital Still CamerasHard Disk DriveMeasurement InstrumentationTFT Panels
