The MAX889RESA is an inverting charge pump IC designed by Analog Devices / Maxim Integrated. It provides a regulated negative output voltage at loads up to 200mA, operating with input voltages from 2.7V to 5.5V. The output voltage is adjustable from -2.5V to -VIN.
Key electrical specifications include a maximum output current of 200mA and a switching frequency of 500kHz. The device features a low output resistance of 0.05 Ohm in regulation and a 0.1µA logic-controlled shutdown mode. It also includes soft-start and foldback current limiting, along with short-circuit and thermal shutdown protection.
This component is housed in an 8-pin SO package and is designed for surface mount applications. The operating temperature range is -40°C to 85°C (TA). Its adjustable negative output makes it suitable for various applications requiring a negative voltage rail from a positive supply.
Applications include TFT panels, hard disk drives, camcorders, digital cameras, measurement instruments, and other battery-powered devices.
