SLVS720F – JUNE 2008 – REVISED NOVEMBER 2015 TPS7A45xx Low-Noise Fast-Transient-Response 1.5-A Low-Dropout Voltage Regulators
1 Features 3 Description The TPS7A45xx devices are low-dropout (LDO)
regulators optimized for fast transient response. The
device can supply 1.5 A of output current with a
dropout voltage of 300 mV. Operating quiescent
current is 1 mA, dropping to less than 1 ОјA 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 TPS7A45xx
regulators have very-low output noise, which makes
them ideal for sensitive RF supply applications. 1 Optimized for Fast Transient Response
