单输出 LDO、1.0A、固定电压 (3.3V)、低噪声、高 PSRR
Ultralow-Noise, High PSRR, Fast, RF, 1A, Low-Dropout Linear Regulators
TPS79633DCQR和TPS79633KTTR说明
The TPS796xx 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, 3 × 3 SON, SOT223-6, and DDPAK-5 packages. Each device in the family is stable with a small 1μ ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 250mV at 1A). Each device achieves fast start-up times (approximately 50μs with a 0.001μF 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 1μA.
