max8893. MAX889, MAX168x and other have a VERY LIMITED CURRENT, because of their limited power dissipation to 471mW at 70C. This allows for around 40mA with MAX1680.The MAX889 inverting charge pump delivers a regulated negative output voltage at loads of up to 200mA. The device operates with inputs from 2.7V to 5.5V to produce an adjustable, regulated
