The TPS73401DDCT is a low-dropout (LDO) low-power Linear Regulator offers excellent AC performance with very low ground current. High power-supply rejection ratio (PSRR), low noise, fast start-up and excellent line and load transient response are provided while consuming a very low 44µA (typical) ground current. The device is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a typical dropout voltage of 125mV at 250mA output. The device uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% over all load, line, process and temperature variations.
