High-Frequency, Regulated,  
200mA, Inverting Charge Pump  
General Description  
Features  
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  
o 200mA Output Current  
o Up to 2MHz Switching Frequency  
o Small Capacitors (1µF)  
an adjustable, regulated output from -2.5V to -V .  
IN  
The MAX889 is available with an operating frequency of  
2MHz (T version), 1MHz (S version), or 0.5MHz (R ver-  
sion). The higher switching frequency devices allow the  
use of smaller capacitors for space-limited applica-  
tions. The lower frequency devices have lower quies-  
cent current.  
o +2.7V to +5.5V Input Voltage Range  
o Adjustable Regulated Negative Output  
(-2.5V to -V )  
IN  
o 0.1µA Logic-Controlled Shutdown  
o Low 0.05Output Resistance (in regulation)  
o Soft-Start and Foldback Current Limited  
o Short-Circuit and Thermal Shutdown Protected  
o 8-Pin SO Package  
The MAX889 also features a 0.1µA logic-controlled  
shutdown mode and is available in an 8-pin SO pack-  
age. An evaluation kit, MAX889SEVKIT, is available.
