  We report the phase diagram of infinite layer Pr$_{1-x}$Sr$_{x}$NiO$_2$ thin
films synthesized via topotactic reduction from the perovskite precursor phase
using CaH$_2$. Based on the electrical transport properties, we find a
doping-dependent superconducting dome extending between $x$ = 0.12 and 0.28,
with a maximum superconducting transition temperature $T_{\rm{c}}$ of 14 K at
$x$ = 0.18, bounded by weakly insulating behavior on both sides. In contrast to
the narrower dome observed in Nd$_{1-x}$Sr$_{x}$NiO$_2$, a local $T_{\rm{c}}$
suppression near $x$ = 0.2 was not observed for the Pr$_{1-x}$Sr$_{x}$NiO$_2$
system. Normal state Hall effect measurements indicate mixed carrier
contributions of both electrons and holes, and show a sign change in the Hall
coefficient as functions of temperature and $x$, quite similar to that in
Nd$_{1-x}$Sr$_{x}$NiO$_2$. Also similar is the observation of a minimum in the
normal state resistivity associated with the superconducting compositions.
These findings indicate an infinite layer nickelate phase diagram that is
relatively insensitive to the rare-earth element, but suggest that disorder
arising from the variations of the ionic radii on the rare-earth site affects
the superconducting dome.
