TPS7A14 1A Ultra-Low Dropout Voltage Regulator Texas Instruments TPS7A14 1A Ultra-Low Dropout (LDO) Voltage Regulator is a small, ultra low-dropout regulator (LDO) with an excellent transient response. This device can source 1A with outstanding ac performance (load and line transient responses). The input voltage range is 0.7V to 2.2V, and the output range is 0.5V to 2.05V with very high accuracy of 1% over load, line, and temperature.
