LTC1261CS8#PBF

LTC1261 is a switched-capacitor voltage inverter designed to provide a regulated negative voltage from a single positive supply. It is optimized for applications which use a 5V or higher supply or which require low output voltages. It requires a single external 0.1µF capacitor and provides adjustable and fixed output voltage. It requires one or two external 0.1µF capacitors, depending on input voltage. Both versions require additional external input and output bypass capacitors. An optional compensation capacitor at ADJ/COMP can be used to reduce the output voltage ripple. It is widely used in application such as GaAs FET bias generators, negative supply generators, battery-powered systems, single supply applications etc.

• Can provide regulated -5V from a 3V supply
• REG pin indicates output is in regulation
• Low output ripple is 5mV typical
• Supply current is 600µA typ
• Adjustable or fixed output voltages
• Requires only three or four external capacitors
• Upto 15mA output current
• SHDN input current is 5µA typical at (VSHDN = VCC)
• Operating temperature is 0°C to 70°C
• Package style is 8-lead NSOIC
