1.5V Linear Regulator recommendation

Other Parts Discussed in Thread: TPS7H1111-SP

I am working a space system project that needs a linear regulator with the following characteristics:

Vout = 1.5 volts

Vin = 3.3V

Iout = 4.5A to 5A

Dropout voltage <= 200 mV with I Load = 750mA

Low noise: Noise <= 50 uV rms (10 kHz - 100 kHz) for Vout = 5V

Low Quiescent Current

Space Quality / Qualifiable to Class V requirements IAW MIL-PRF-38535

Radiation Hardness >= 50 krads (Si) to 100 krads (Si)

LET: > 45 MeV-cm^2/mg

Can the local Washington DC, Maryland, Northern Virginia TI representative contact me to discuss options/
