TPS79933-Q1 - Texas Instruments

TPS79933-Q1 Linear Regulator

The TPS799xx-Q1 family of low-dropout (LDO) lowpower linear regulators 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 TPS799xx-Q1 is stable with ceramic c.
