TPS71918-28DRVR

双通道， 200mA输出，低噪声，高PSRR低压差线性稳压器，采用2mm x 2mm SON封装 Dual, 200mA Output, Low Noise, High PSRR Low-Dropout Linear Regulators in 2mm x 2mm SON Package

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 90µA 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.
