TPS79901DDCT

The TPS79901DDCT 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 40µA typical ground current. The device is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of typically 100mV at a 200mA output. The device uses a precision voltage reference and feedback loop to achieve an overall accuracy of 2% over all load, line, process and temperature variations. The device features inrush current protection when the EN toggle is used to start the device, immediately clamping the current. A noise-reduction pin is provided to bypass noise generated by the band-gap reference and to improve PSRR, while a quick-start circuit quickly charges this capacitor at start-up.
