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 μA 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.

Output voltage range is from 1.21 to 20 V. The

TPS7A45xx regulators are stable with output

capacitance as low as 10 μF. 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. The devices are available

in fixed output voltages of 1.5 V, 1.8 V, 2.5 V, 3.3 V,

and as an adjustable device with a 1.21-V reference

voltage.
