• Manufacturer Part Number: MAX5006
• Description: 150mA USB LDO Regulators with +15kV -15kV TVS and UP Reset
• Manufacturer: MAXIM [Maxim Integrated Products]

The MAX5005/MAX5006/MAX5007 are USB applica-
tion-specific, low-dropout, low-quiescent current linear
regulators with an integrated µP reset circuit (see
Figure 1). The devices drive loads up to 150mA and
are available with a fixed output voltage of +3.3V.
Features include 1.5k
and ±15kV transient voltage suppression (TVS) in
accordance with IEC1000-4-2 (EN61000-4-2) Air
Discharge Method and MILSTD883C- Method 3015-6
making the MAX5005/MAX5006/MAX5007 ideal for use
with USB peripheral devices. The internal reset circuit
monitors the regulator output voltage and asserts a
reset signal when the output is typically -7.5% out of
regulation for MAX500_ACUB and -12.5% out of regula-
tion for MAX500_BCUB.

The reset supervisor circuit is fully integrated in the
MAX5005/MAX5006/MAX5007, and uses the same ref-
erence voltage as the regulator. Two supply tolerance
reset thresholds, typically -7.5% and -12.5%, are avail-
able for each type of device.
7.5% reset: Reset does not assert until the regulator
output voltage is at least -3.6% out of tolerance and
always asserts before the regulator output voltage is
-11.5% out of tolerance.
12.5% reset: Reset does not assert until the regulator
output voltage is at least -8.8% out of tolerance and
always asserts before the regulator output voltage is
-16.7% out of tolerance.
The MAX5005/MAX5006/MAX5007 µP supervisory cir-
cuits assert a reset during power-up, power-down, and
