Product Specification
Revision 1.3
BQ8211
Low Dropout
300mA Voltage Regulator
with Enable
September 13, 2006
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.
