TPS71719 单路输出 LDO、150mA、固定电压 (1.9V)、低噪声、高 PSRR
TPS71719 描述
The TPS717xx family of low-dropout (LDO), low-power linear regulators offers very high power supply rejection (PSRR) while maintaining very low 45µA ground current in an ultra-small, five-pin SC70 package. The family uses an advanced BiCMOS process and a PMOSFET pass device to achieve fast start-up, very low noise, excellent transient response, and excellent PSRR performance. The TPS717xx is stable with a 1.0µF ceramic output capacitor, and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% over all load, line, process, and temperature variations. It is fully specified from TJ = -40°C to +125°C and is offered in a small SC70-5 package, a 2mm × 2mm SON-6 package with a thermal pad, and a 1.
