TPS2220B CONTROL LOGIC
ESD PROTECTIONS (see Figure 35)
Maximum recommended output capacitance for AVCC is 220
F including card capacitance, and for AVPP is 10 F, without OC glitch when
switches are powered on.

All inputs and outputs of these devices incorporate ESD-protection circuitry designed to withstand a 2-kV
human-body-model discharge as defined in MIL-STD-883C, Method 3015. The AVCC and AVPP outputs can be
exposed to potentially higher discharges from the external environment through the PC Card connector.
Bypassing the outputs with 0.1-F capacitors protects the devices from discharges up to 10 kV.
