LT6654
Typical perForMance characTerisTics The characteristic curves are similar across the LT6654 family. Curves from the LT6654-1.25, LT6654-2.5 and the LT6654-5 represent the full range of typical performance of all voltage options. Characteristic curves for other output voltages fall between these curves and can be estimated based on their output. 1.25V Output Voltage 1.25V Output Impedance Temperature Drift 1.25V Turn-On Characteristics vs Frequency
