Hot-selling and scarce TPS78633KTTT Ultralow-Noise, High-PSRR, Fast, RF, 1.5-A Low-Dropout Linear Regulators TO263-5 spot stock

Product Descriptions

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 advanced, proprietary BiCMOS fabrication process to 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 quiescen 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.
