TPS7A11 Ultra-Low Dropout Linear Regulators Texas Instruments TPS7A11 Ultra-Low Dropout Linear Regulators (LDOs) can source 500mA 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% over load, line, and temperature. This performance is ideal for supplying power to the lower core voltages of modern microcontrollers (MCUs) and analog sensors.
