TPS79912DDCTG4 Description
The TPS79912DDCTG4 low-dropout (LDO)， low-power linear regulator offers excellent ac performance with the shallow ground current. High power-supply rejection ratio (PSRR), low noise, fast start-up, and perfect line and load transient response are provided while consuming a very low 40-μA (typical) ground current. The TPS79912DDCTG4 is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of typically 100 mV at a 200-mA output. The TPS79912DDCTG4 uses a precision voltage reference and feedback loop to achieve an overall accuracy of 2% over all load, line, process, and temperature variations. The TPS79912DDCTG4 features inrush current protection when the EN toggle is used to start the device, immediately clamping the current.
