The TPS71733DCKT is a 3.3V fixed output low-dropout (LDO) low-power Linear Regulator offers very high power-supply rejection (PSRR) while maintaining very low 45µA ground current. The device uses an advanced BiCMOS process and a PMOS pass device to achieve fast start-up, very low noise, excellent transient response and excellent PSRR performance. The device is stable with a 1µF 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.
70dB at 1kHz, 67dB at 100kHz and 45dB at 1MHz ultra-high PSRR
