Product Description
Maxim Integrated MAX889SESA+ voltage regulator is an inverting charge pump that delivers a regulated negative output voltage with a power rating of 471mW. It operates from a wide input voltage range of 2.7V to 5.5V and provides an adjustable output from -2.5V to the negative input voltage. The device is housed in a compact SOIC 8-pin surface mount package measuring 3.1mm in length and width and 1.1mm in height, making it suitable for space-constrained applications.
The MAX889SESA+ supports output currents up to 200mA and offers switching frequency options from 0.5MHz to 2MHz, allowing designers to choose between lower quiescent current or smaller capacitor sizes depending on application requirements. It features advanced power-saving technology with a logic-controlled shutdown mode consuming only 0.1μA. Additional protection features include short-circuit protection, thermal shutdown, soft-start, and foldback current limiting to ensure reliable operation and device longevity.
This Voltage Regulator is ideal for battery-powered devices, camcorders, digital still cameras, hard disk drives, measurement instrumentation, and TFT panels. Its negative output capability and surface mount design enable efficient power management in compact electronic systems.
Operates within 2.7V to 5.5V input range. Adjustable negative output voltage from -2.5V to -VIN. Up to 200mA output current capability. Logic-controlled shutdown with ultra-low current consumption. Short-circuit and thermal shutdown protection.
