Maxim - nanoPower Boost Regulators

Using ultra-low quiescent current, our high-efficiency nanoPower regulators enable the longest battery life by maximizing run time, standby, and shelf life. Total solution size is reduced by up to 50% and heat dissipation is minimized with over 95% peak efficiency. This makes our nanoPower regulators ideal for small, battery operated and low power devices such as those designed for wearable, IoT and wireless applications.
