LT1761 LDO Regulators Analog Devices LT1761 Low Dropout (LDO) Regulators offer micropower operation while being capable of supplying 50ma output current with a dropout voltage of 300mA. These regulators follow linear behavior and are specifically designed to be used in battery-powered or high-voltage systems. The LT1761 LDO regulators deliver low quiescent current and are capable of operating with very small output capacitors.
