3 Description
The TPS793xx-Q1 family of low-dropout (LDO) lowpower linear
voltage regulators features high powersupply rejection ratio (PSRR), ultralow noise, fast start-up, and excellent line and load transient responses in a small-outline SOT-23 package. Each TPS793-Q1 device in the family is stable, with a small 2.2-μF ceramic capacitor on the output. The TPS793x...
