The TPS786 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, SOT223-6 and DDPAK-5 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, 390 mV at 1.5 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). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 µA. The TPS78630 exhibits approximately 48 µVRMS of output voltage at 3-V output noise with a 0.1-µF bypass capacitor. Applications with analog components that are noise sensitive, such as portable RF electronics, benefit from the high PSRR, low noise features, and the fast response time.

The Texas Instruments DEM-SOT223LDO demonstration module (DEM) helps designers evaluate the operation and performance of Texas Instruments low-dropout regulators (LDOs). This module is compatible with most positive output LDOs offered in the SOT223 (DCQ) package.
The TUSB8040AEVM board is a free-standing reference design for a four-port SuperSpeed USB (USB 3.0) hub. It is used to evaluate system compatibility. A SuperSpeed enabled host system and cable is required to evaluate SuperSpeed data transfer. The TUSB8040AEVM will work with USB 2.0 hosts systems as (...)
