Input and Output Capacitance
Output Transient Response (Dynamic Loading)
The power supply requires the following capacitance (or equivalent) on the PWB.
The output voltages will remain within their regulation limits specified for the load steps defined
below. The maximum over/undershoot voltages will not exceed those defined below and will not
cause any over or undervoltage detection circuits to activate. The load slew rate will not exceed
10A/μS. Recommended input and output capacitors should be used to meet the Spec.
