LT1461
Typical perForMance characTerisTics Characteristic curves are similar for most LT1461s. Curves from the LT1461-2.5 and the LT1461-5 represent the extremes of the voltage options. Characteristic curves for other output voltages fall between these curves and can be estimated based on their output. 2.5V Transient Response to 10mA 2.5V Output Noise Load Step 2.5V Line Transient Response 0.1Hz ≤ f ≤ 10Hz
