The MAX870EUK+T from Analog Devices is a charge pump IC designed to generate a negative bias voltage for LCD panels. It takes a positive input from 1.4V to 5.5V and inverts it to a regulated negative output between -1.4V and -5.5V, delivering a single output in a compact SOT-23-5 package. Typical applications include portable LCD displays, handheld instruments, and battery-powered equipment where a small negative rail is needed without an inductor.
Temperature grade and environment
Rated for -40°C to 85°C operating temperature, this part handles outdoor telecom gear, factory-floor terminals, and automotive cabin electronics (non-engine bay). The SOT-23-5 package is a standard footprint for low-power bias generators; it sits flat on the PCB with no heatsink required at the milliwatt output levels typical of LCD bias loads.
Lifecycle and sourcing
No second-source or direct replacement is listed in the official records.
