BQ8211 Low Dropout 300mA Voltage Regulator with Enable Product Specification Revision 1.3 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. Applications • Graphic cards and PC motherboards • Cell Phones • DVD video player Replacement for: • LX8211 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 Typical Application www.acutechnology.com BQ8211 Acutechnology Semiconductor Inc.
