The TPS7A4533KTTR is a 3.3V fixed output low-dropout (LDO) Linear Regulator optimized for fast transient response. The device can supply 1.5A of output current with a dropout voltage of 300mV. Operating quiescent current is 1mA, dropping to less than 1µA in shutdown. Quiescent current is well controlled, it does not rise in dropout as with many other regulators. In addition to fast transient response, the device has very-low output noise, which makes them ideal for sensitive RF supply applications. The device is stable with output capacitance as low as 10µF. Small ceramic capacitors can be used without the necessary addition of ESR as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse-current protection.
