TPS799 - Texas Instruments

TPS799 High-PSRR Low-Dropout Linear Regulator

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 use.
