150mA USB LDO Regulators with ±15kV TVS
and μP Reset
Note that some ceramic dielectrics exhibit large capac-
itance and ESR variation with temperature. With
dielectrics such as Z5U and Y5V, it may be necessary
to use 2.2μF or more to ensure stability at temperatures
below -10°C. With X7R or X5R dielectrics, 1μF should
be sufficient at all operating temperatures. Also, for
high-ESR tantalum capacitors, 2.2μF or more may be
needed to maintain stability. A graph of the Region of
Stable C OUT ESR vs. Load Current is shown in the
Typical Operating Characteristics .
To improve power-supply rejection and transient
response use a 1μF capacitor between IN and GND.
Negative-Going V OUT Transients
These devices are relatively immune to short-duration,
negative-going V OUT transients. The Typical Operating
Characteristics section shows a graph of the Maximum
Pulse Duration vs. Reset Threshold Overdrive for which
reset is not asserted. The graph was produced using
negative going output transients starting at V OUT and
ending below the reset threshold by the magnitude
indicated (Reset Threshold Overdrive). The graph
shows the maximum pulse width that a negative going
V OUT transient can typically have without triggering a
reset pulse. As the amplitude of the transient increases
(i.e., goes further below the reset threshold), the maxi-
mum allowable pulse width decreases. Typically, a
V OUT transient that goes only 10mV below the reset
threshold and lasts for 75μs will not trigger a reset
pulse.
USB ±15kV Transient Voltage
Suppression
The universal serial bus (USB) simplifies interconnectiv-
ity between peripheral devices and personal comput-
ers. USBs offer high-speed data communication rates
(up to 12Mbps) using only two lines (D+ and D-).
CMOS based USB peripherals that utilize deep submi-
cron technologies are more susceptible to electrostatic
discharge (ESD) failure due to shorter channel lengths,
shallower drain/source junctions, and lightly doped
drain structures. The MAX5005/MAX5006/MAX5007
incorporate a proprietary transient voltage suppression
(TVS) circuit for use with submicron devices.
The TVS design complies with IEC-1000-4-2 level 4
(EN61000-4-2) ±15kV Air Discharge and ±8kV Contact
Discharge as well as MIL STD 883C-Method 3015-6
level 3.
The TVS circuit handles up to 11A of surge current. The
TVS/ESD structure is directly coupled to the output of
the LDO regulator.
TVS Surge Test Information
Figure 2 shows the test circuit used to generate the
8/40μs short circuit waveform of Figure 3. Figures 4, 5,
and 6 show the actual surge current I/V characteristics
with various capacitive loads.
ESD Performance
The MAX5005/MAX5006/MAX5007 are characterized
to the following limits on D+, D-, and IN:
? ±15kV using the Human Body Model
? ±8kV using the Contact Discharge Method specified
in IEC 1000-4-2 (EN61000-4-2)
? ±15kV using the Air-Gap Discharge Method speci-
fied in IEC 1000-4-2 (EN61000-4-2).
Note that in order to achieve the above ESD levels on
IN, a ceramic 1μF ceramic capacitor should be con-
nected from IN to GND.
ESD Test Conditions
ESD performance depends on several conditions.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.
Human Body Model
Figure 7 shows the Human Body Model, and Figure 8
shows the current waveform it generates when dis-
charged into low impedance. This model consists of a
100pF capacitor charged to the ESD voltage of interest,
which is then discharged into the test device through a
1.5k ? resistor.
ESD Transmission Line Pulsing
Figure 9 shows the test circuit used for transmission
line pulsing conditions. The 200ns pulsewidth has a
rise time of 4ns. Figure 10 shows the Current vs.
Voltage characteristics for various output capacitance
values.
