Overview
UNISONIC TECHNOLOGIES CO.
, LTD UC5301 SWITCHED-CAPACITOR VOLTAGE INVERTERS  DESCRIPTION The UTC UC5301 is an unregulated charge-pump voltage inverter.
It can be used to generate a negative supply from positive input.
Input voltages varying from +1.
8V to +5V can be inverted into a -1.
8V ~ -5V output supply.
The device can be operated on a 0.
45mA typical current from supplies 3.
3V, which meets the requirements of battery-powered and board level voltage conversion applications.
The UTC UC5301 can deliver 25mA output current with a voltage drop of 250mV.
The parts are over-temperature protected.
The UTC UC5301 is generally used in cell phones, PDAS, and other portable equipments, small LCD panels, handy-terminals.
 FEATURES * Operating voltage range: 1.
8V ~ 5V * Inverts input supply voltage * 25mA output current with a voltage drop of 250mV * Quiescent current 0.
