3 Description
The TPS795 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, 6-pin SOT-223 and 3-mm × 3-mm VSON packages. 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, 110 mV at 500 mA). 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). Moreover, when the device is placed in standby mode, the supply current...
