MAX5005BCUB
150mA USB LDO Regulators with ±15kV TVS and µP Reset
General Description
The MAX5005/MAX5006/MAX5007 are low-dropout
(LDO), micropower linear voltage regulators with an
integrated microprocessor (µP) reset circuit for use with
USB peripheral devices. Each device is available with a
fixed +3.3V output voltage and can deliver up to
150mA load current. Each device features ±15kV tran-
sient voltage suppression (TVS) as well as precision
1.5kΩdata-line termination resistors for USB digital sig-
nals making them ideal for use with USB peripherals.
The MAX5005/MAX5006/MAX5007 include an internal
reset circuit that enables the USB microcontroller
100ms after the LDO regulator output voltage reaches
regulation. Reset outputs are available in push-pull
(active-low or active-high) and open-drain (active-low)
options.
The MAX5005/MAX5006/MAX5007 are optimized for
use with a 1µF ceramic output capacitor. Each device
includes thermal shutdown protection, output short-cir-
cuit protection, and output to input reverse leakage pro-
tection. These devices also include an active-low
manual reset input.
The MAX5005 features an open-drain reset output, the
MAX5006 features an active-low push-pull reset output,
and the MAX5007 features an active-high push-pull
reset output. Each device is available in a space-saving
10-pin µMAX package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
