DESCRIPTION

The TPS718xx and TPS719xx families of low-dropout(LDO) regulators offer a high power-supply rejectionratio (PSRR), low noise, fast start-up, and excellentline and load transient responses while consuming avery low 90uA (typical) at no load ground current withboth LDOs enabled. The TPS719xx also provides anactive pulldown circuit to quickly discharge outputloads. The TPS718xx and TPS719xx are stable withceramic capacitors and use an advanced BiCMOSfabrication process to yield a typical dropout voltageof 230mV at 200mA output loads. The TPS718xx andTPS719xx also use a precision voltage reference andfeedback loop to achieve 3% overall accuracy over allload, line, process, and temperature variations. Bothfamilies of devices are fully specified from T = -40°Cto +125°C and are offered in 2mm x 2mm SON-6 and6-ball Wafer Chip-Scale (WCSP) packages that areideal for applications such as mobile handsets andWLAN that require good thermal dissipation whilemaintaining a very small footprint.
