Overview: Order this document by MC34270/D Liquid Crystal Display and Backlight Integrated Controller The MC34270 and MC34271 are low power dual switching voltage regulators, specifically designed for handheld and laptop applications, to provide several regulated output voltages using a minimum of external parts. Two unmitted switching regulators feature a very low standby bias current of 5.0 µA, and an operating current of 7.0 mA capable of supplying output currents in excess of 200 mA.
This datasheet includes multiple variants, all published together in a single manufacturer document.
