Hot-selling and scarce TPS78625KTTT Low-Dropout Linear Regulators TO263 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 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 μV_RMS 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.
