Capacitors for LDOs
For LDOs, the required output capacitance is depen-
dent on the load currents. With rated maximum load
currents, 2.2FF (typ) capacitors are recommended for
LDO1, LDO2, LDO3, and LDO5 and a 1.0FF capacitor is
recommended for LDO4. For loads less than 150mA, it
is sufficient to use 1.0FF capacitors for stable operation
over the full temperature range for LDO1, LDO2, LDO3,
and LDO5. Reduce output noise and improve load tran-
sient response, stability, and power-supply rejection by
using larger output capacitors.
USB High-Speed Switch
USB Switching
The USB high-speed switch is fully compliant with the
USB 2.0 specification. The low on-resistance and low
on-capacitance of these switches make it ideal for high-
performance switching applications. It is ideal for routing
USB data lines (see Figure 14) and for applications that
require switching between multiple USB hosts (see Figure
15). The USB switch also features overvoltage fault pro-
tection to guard systems against shorts to the USB VBUS
voltage that is required for all USB applications.
Extended ESD Protection
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against electrostatic
discharges encountered during handling and assembly.
COM1 and COM2 are further protected against static
electricity. The state-of-the-art structures are developed
to protect these pins against ESD up to ±15kV without
damage. The ESD structures withstand high ESD in nor-
mal operation and when the device is powered down.
After an ESD event, the USB switch continues to function
without latchup.
The USB high-speed switch is characterized for protec-
tion to the following limits:
U
±15kV using Human Body Model
U
±8kV using IEC 61000-4-2 Contact Discharge method
U
±15kV using IEC 61000-4-2 Air-Gap Discharge method
