200-mA RF Low-Dropout Regulator
With Enable
Available in 1.8-V, 2.5-V, 3-V, 3.3-V, and
Adjustable (1.22-V to 5.5-V)
High PSRR (68dB at 1 kHz)
Ultralow-Noise (23 碌V
RMS
, TPS73018)
Fast Start-Up Time (50 碌s)
Stable With a 2.2-碌F Ceramic Capacitor
Excellent Load/Line Transient Response
Very Low Dropout Voltage (120 mV at Full
Load)
5- and 6-Pin SOT23 (DBV) Package
DESCRIPTION
The TPS730xx 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 a small SOT23 package. Each device in
the family is stable, with a small 2.2-碌F ceramic
capacitor on the output. The TPS730xx family uses
an advanced, proprietary BiCMOS fabrication pro-
cess to yield low dropout voltages (e.g., 120 mV at
200 mA, TPS73030). Each device achieves fast
start-up times (approximately 50 碌s with a 0.001-碌F
bypass capacitor) while consuming low quiescent
current (170 碌A(chǔ) typical). Moreover, when the device
is placed in standby mode, the supply current is
reduced to less than 1 碌A(chǔ). The TPS73018 exhibits
approximately 23 碌V
RMS
of output voltage noise at
2.8-V output with a 0.01-碌F bypass capacitor. Appli-
cations 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.
