TPS7A14 - Texas Instruments

TPS7A14 Ultra-Low Dropout Regulator

The TPS7A14 is a small, ultra low-dropout regulator (LDO) with excellent transient response. This device can source 1 A with outstanding ac performance (load and line transient responses). The input voltage range is 0.7 V to 2.2 V, and the output range is 0.5 V to 2.0 V with a very high accuracy of 1% over load, line, and temperature. The primary power pat.
