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 (e.g., 38 mV at 100 mA, TPS79147). Each device achieves fast start-up times (approximately 63 µs with a 0.001 µF bypass capacitor) while consuming very low quiescent current (170 µA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 µA. The TPS79118 exhibits approximately 15 µVRMS of output voltage 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 and low noise features as well as the fast response time. 3 2 4 5 DBV PACKAGE (TOP VIEW) 1 IN GND EN OUT BYPASS 3 2 4 6 DBV PACKAGE (TOP VIEW) 1 IN EN OUT BYPASS 5 FB Adjustable Option Fixed Option 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 100 1 k 10 k 100 k IO = 1 mA VO = 4.3 V Co = 1 µF C(byp) = 0.1 µF IO = 100 mA f − Frequency − Hz TPS79133 OUTPUT SPECTRAL NOISE DENSITY vs FREQUENCY 60 50 30 20 10 100 1 k 10 k 70 90 100 100 k 1 M 10 M 40 80 f − Frequency − Hz TPS79133 RIPPLE REJECTION vs FREQUENCY VI = 4.3 V Co = 10 µF C(byp) = 0.01 µF IO = 10 mA IO = 100 mA GND PRODUCTION DATA information is current as of publication date.
