LTC1261IS8PBF Description

Short technical summary and product information.

The LTC1261IS8PBF is a switched-capacitor voltage inverter manufactured by Linear Technology. Designed to provide a regulated negative voltage from a single positive supply, it operates within a supply voltage range of 3V to 8V. This component is capable of delivering up to 15mA of output current with low output ripple, typically 5mV.

 

Key features include adjustable or fixed output voltage options, with specific fixed outputs like -4V and -4.5V available. The device also offers a low supply current of 600µA typical, which drops to 5µA in shutdown mode. It requires only a few external capacitors, simplifying circuit design.

 

The LTC1261IS8PBF is supplied in an 8-lead SO package, making it suitable for surface-mount applications. Its operating temperature range is -40°C to 85°C. This device is part of the LTC1261 series, which focuses on inductorless DC/DC converters and GaAsFET bias generators.
