... Output voltage is always measured at 25°C, but the IC is cycled to the hot or cold temperature limit before successive measurements. For instruments that are stored at well controlled temperatures (within degrees of operational temperature) hysteresis is usually not a dominant error source. LT6656 = 0, unless otherwise noted.

... With its low sensitivity to ESR, the LT6656 is stable with a wide variety of capacitor types including ceramic, tantalum and electrolytic. The test circuit in Figure 2 was used to test the response and stability of the LT6656 to various load currents. The resultant transient responses can be seen in Figure 3 and Figure 4. The large scale out- ...

... Figure 7. Detailed Output Response to a 0.5V Input Step Output Noise In general, output noise in the LT6656 is proportional to the bandwidth of the output stage and therefore increases with higher load current and lower output capacitance. However 2ms peaking in the noise response may be the dominant factor in determining the output noise level ...
