Overview
Description
The LTC1261L is a switched-capacitor voltage inverter that provides a regulated negative voltage from a single positive supply. It operates from a 2.7V to 5.25V supply and offers adjustable output voltages from -1.23V to -5V. The LTC1261L-4/LTC1261L-4.5 require a 4.5V to 5.25V supply and provide fixed output voltages of -4V and -4.5V, respectively.

Features
Regulated negative voltage from a single positive supply
Adjustable or fixed output voltages
Output regulation: ±4.5%
Supply current: 650µA (typical)
Shutdown mode drops supply current to 5μA
Up to 20mA output current
Requires only three or four external capacitors
Open-drain REG output indicates output regulation
Available in MS8 and SO-8 packages

Applications
GaAs FET bias generators
Negative supply generators
Battery-powered systems
Single supply applications
