DESCRIPTION
The TPS7A4501 is a low-dropout (LDO) regulator 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 TPS7A4501 regulator has very low output noise, which
makes it ideal for sensitive RF supply applications.
Output voltage range is from 1.21 V to 20 V. The TPS7A4501 is 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 device is available as an adjustable device with a 1.21-V reference voltage. The
TPS7A4501 regulator is available in the 10-pin GDFP (U) package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
