DESCRIPTION
The TPS796xx-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 SOT223-6 package. Each device in the family is stable with a small 1-μF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 250 mV at 1 A). Each device achieves fast start-up times (approximately 50 μs with a 0.001-μF bypass capacitor) while consuming very low quiescent current (265 μA typical)....
