MAX889RESA+ Description

Short technical summary and product information.

The MAX889RESA+ is a high-frequency, regulated, inverting charge pump IC manufactured by Analog Devices (formerly Maxim Integrated). It is designed to deliver a regulated negative output voltage at loads up to 200mA.

 

The device operates from an input voltage range of +2.7V to +5.5V, producing an adjustable regulated output from -2.5V to -VIN. It features a switching frequency of 500kHz, allowing for the use of small capacitors, and includes a logic-controlled shutdown mode with a low quiescent current of 0.1µA.

 

Key electrical characteristics include a low output resistance of 0.05Ω in regulation, soft-start, and foldback current limiting. The MAX889RESA+ also incorporates short-circuit and thermal shutdown protection for enhanced reliability.

 

Packaged in an 8-pin SOIC surface mount package, this charge pump is suitable for space-limited applications. Its features make it ideal for battery-powered devices, TFT panels, hard disk drives, camcorders, digital cameras, and measurement instruments.
