TPS79301DBVRQ1

The TPS793xx-Q1 family of low-dropout (LDO) lowpower linear voltage regulators features high powersupply rejection ratio (PSRR), ultralow noise, fast
start-up, and excellent line and load transient
responses in a small-outline SOT-23 package. Each
TPS793-Q1 device in the family is stable, with a small
2.2-μF ceramic capacitor on the output. The
TPS793xx-Q1 family uses an advanced, proprietary,
BiCMOS fabrication process to yield extremely low
dropout voltages (for example, 112 mV at 200 mA,
TPS79330-Q1). Each device achieves fast start-up
times (approximately 50 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 TPS79328-Q1
exhibits approximately 32 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.
