3.4.6 Voltage ripple.
3.4.6.1 Type I. Not applicable.
3.4.6.2 Types II and III. The regulator output voltage waveform shall have the following
limitations. The ac peak to peak ripple voltage shall be no more than 7 V. With batteries
connected, the peak to peak ripple voltage shall be no greater than 4 V, except that excursions of
less than 1 millisecond (ms) may exceed 4 V (see 4.5.5). For type III only, this requirement shall
be met with pin "E" of the battery connector grounded and ungrounded.
