9 Power Supply Recommendations

The input supply to the LMS8117A must be kept at a voltage level such that its maximum rating is not exceeded. The minimum dropout voltage must also be met, with extra headroom when possible, to keep the device in regulation. TI recommends an input capacitor; see External Capacitors and Stability for more information on capacitor selection.
