General Description
The ultra-small MAX870/MAX871 monolithic, CMOS charge-pump inverters accept input voltages ranging from +1.4V to +5.5V. The MAX870 operates at 125kHz, and the MAX871 operates at 500kHz. Their high efficiency (90%) and low operating current (0.7mA for the MAX870) make these devices ideal for both battery-powered and board-level voltage-conversion applications.

Features
♦ 5-Pin SOT23-5 Package
♦ 99% Voltage Conversion Efficiency
♦ Invert Input Supply Voltage
♦ 0.7mA Quiescent Current (MAX870)
♦ +1.4V to +5.5V Input Voltage Range
♦ Require Only Two Capacitors
♦ 25mA Output Current
♦ Shutdown Control

Applications
    Local -5V Supply from 5V Logic Supply
    Small LCD Panels
    Cell Phones
    Medical Instruments
    Handy-Terminals, PDAs
    Battery-Operated Equipment
