Manufacturer Part Number
MAX5006
Description
150mA USB LDO Regulators with +15kV -15kV TVS and UP Reset
Manufacturer
MAXIM [Maxim Integrated Products]
Datasheet
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
1.5k
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.
