MAXIM MAX889 Hh-Frequency Regulated 200mA Inverting

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 IC is an inverting charge pump that deliv-ers a regulated negative output voltage at loads up to 200mA. The device operates from an input of +2.7V to +5.5V to produce a user
