3 Description
The TPS791 device is a low-dropout (LDO) lowpower linear voltage regulator that features high power-supply rejection ratio (PSRR), ultralow noise, fast start-up, and excellent line and load transient responses in a small outline, SOT23 package. The device is stable, with a small 1-µF ceramic capacitor on the output. The TPS791 uses an advanced, proprietary Bi CMOS fabrication process to yield extremely low dropout voltages (for example, 38 m V at 100 m A, TPS79147). This device achieves fast start-up times...
