/V
RMS
The TPS718xx and TPS719xx families of low-dropout (LDO) regulators offer a high power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient responses while consuming a very low 90 µ A (typical) at no load ground current with both LDOs enabled. The TPS719xx also provides an active pulldown circuit to quickly discharge output loads. The TPS718xx and TPS719xx are stable with ceramic capacitors and use an advanced BiCMOS fabrication process to yield a typical dropout voltage of 230mV at 200mA output loads. The TPS718xx and TPS719xx also use a precision voltage reference and feedback loop to achieve 3% overall accuracy over all load, line, process, and temperature variations. Both families of devices are fully specified from TJ= – 40 ° C to +125 ° C and are offered in 2mm × 2mm SON-6 and 6-ball Wafer Chip-Scale (WCSP) packages that are ideal for applications such as mobile handsets and WLAN that require good thermal dissipation while maintaining a very small footprint.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

TPS718 xx-yywwwz A denotes device with rotated pin 1 orientation of wafer-chipscale package.
TPS718A xx-yywwwz XX is nominal output voltage for LDO1 (for example, 28 = 2.8V).
TPS719 xx-yywwwz YY is nominal output voltage for LDO2.
TPS719A xx-yywwwz WWW is package designator.
Z is tape and reel quantity (R = 3000, T = 250).
Examples: TPS71918 – 285DRVR XX = 18 = 1.8V, YYY = 285 = 2.85V
TPS719185-33DRVR XXX = 185 = 1.85V, YY = 33 = 3.3V
