BQ8211

Low Dropout

300mA Voltage Regulator

with Enable

Product Specification

Revision 1.3

September 13, 2006

Applications

• Graphic cards and PC motherboards

• Cell Phones

• DVD video player

Replacement for:

• LX8211

General Description

The BQ8211 is a low dropout voltage regulator

capable of delivering 300 mA to the load. It is

adjustable and can set a precise voltage from

1.175V to 15V with two external resistors. The

BQ8211 meets all specifications down to 1.175V

output,

unlike

CMOS

LDO’s

which

loose

performance with outputs below 2.25V.

The enable pin provides a remote turn-off for low

power consumption. It draws virtually zero current

while in shutdown mode.

To assure accuracy within 2% over temperature,

the heart of the BQ8211 is a self-correcting

AcuRef™ bandgap reference.

On-chip current limit and thermal shutdown with

hysteresis protects against any combination of

overload and ambient temperature that might

cause the junction temperature to exceed safe

limits.

Features

• Low dropout voltage (980mV at 300 mA)

• Enable pin implements sequencing

• Vout tolerance less than 2 % over

temperature

• Featured in the very small SOT-23

package

• Stable with low cost 1µF capacitor

• Low ground current

• Thermal protection with hysteresis

• Short circuit protection

• RoHS compliant available
