LTC1983ES6-5

The LTC1983ES6-5 is a low-power, charge pump voltage inverter designed by Linear Technology (now part of Analog Devices). It is commonly used in battery-powered applications to provide a negative supply voltage from a positive input voltage. The device operates from an input voltage range of 1.8V to 5.5V and delivers a fixed output voltage of -5V. Packaged in a compact 6-lead SOT-23, it is suitable for space-constrained designs.
Key features of the LTC1983ES6-5 include a high efficiency of up to 90%, low quiescent current, and a shutdown mode that reduces the supply current to less than 1µA, which is ideal for extending battery life. The device operates with a switching frequency of 2MHz, allowing the use of small external capacitors. This makes it suitable for portable electronics, handheld devices, and other applications where a negative voltage is required, but space and energy efficiency are critical. It also requires no inductors, simplifying the design and reducing overall system cost.
