TPS7A10 Ultra-Low Low-Dropout Regulators Texas Instruments TPS7A10 Ultra-Low Low-Dropout Regulators are ultra-small, low quiescent current, low-dropout regulators (LDOs) that can source 300mA with an outstanding ac performance (load and line transient responses). This device has an input range of 0.75V to 3.3V and an output range of 0.5V to 3.0V with a very high accuracy of 1.5% overload, line, and temperature. This performance is ideal for powering the lower core voltages of modern MCUs and analog sensors.
