Features

* o 5-Pin SOT23-5 Package o 99% Voltage Conversion Efficiency o Invert Input Supply Voltage o 0.7mA Quiescent Current (MAX870) o +1.4V to +5.5V Input Voltage Range o Require Only Two Capacitors o 25mA Output Current o Shutdown Control MAX870/MAX871 ______________Ordering Information PART MAX870C/D M

Applications

* Oscillator control circuitry and four power MOSFET switches are included on-chip. A typical MAX870/ MAX871 application is generating a -5V supply from a +5V logic supply to power analog circuitry. Both parts come in a 5-pin SOT23-5 package and can deliver 25mA with a voltage drop of 500mV. For appl
