TPS71933-33DRVR
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
DESCRIPON
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.
