Power Supply Recommendations

The TPS7H2140-SEP is designed to operate from an input range between 4.5 V to 32 V. This supply voltage must be well regulated and proper local bypass capacitors should be used for proper electrical performance from VIN to GND. Due to stringent requirements for space applications, typically numerous input bypass capacitors are used and the total capacitance is much larger than for commercial applications. The TPS7H2140-SEP evaluation module uses one 33-µF tantalum capacitor in parallel with one 10-µF, one 1-µF, and one 0.1-µF ceramic capacitor.
