3 Description
The TPS796 family of low-dropout (LDO) low-power linear voltage
regulators features high power-supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses in small outline, 3 × 3 VSON, SOT223-6, and TO-263 packages. Each device in the family is stable with a small, 1-μF ceramic capacitor on the output. The family uses an advanced, propriet...
