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.
