3 Description
The TPS799 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 40-μA (typical) ground current.
The TPS799 is stable with ceramic
capacitors and uses an advanced Bi
CMOS fabrication process to yield a dropout
voltage of typically 100 mV at a 200mA output. The TPS799 uses a precision
voltage reference and feedback loop to achieve an overall accuracy of 2% over all load, line, process, and temperature variations. The TPS799 features inrush current protection when ...
