DESCRIPTION
The TPS713xx family of low-dropout (LDO) voltage
regulators is tailored to noise-sensitive and RF appli-
cations. These products feature dual 250 mA LDOs
with ultralow noise, high power-supply rejection ratio
(PSRR), and fast transient and start-up response.
These devices also feature an integrated supply
voltage supervisor (SVS) that monitors the voltage at
OUT2 and will assert if the voltage falls to 95%
(typical) of the measured output. Each regulator
output is stable with low-cost 2.2 碌F ceramic output
capacitors and features very low dropout voltages
(125 mV typical at 250 mA). Each regulator achieves
fast start-up times (approximately 60 碌s with a
0.001 碌F bypass capacitor) while consuming very low
quiescent current (300 碌A(chǔ) typical with both outputs
enabled). When the device is placed in standby
mode, the supply current is reduced to less than
0.3 碌A(chǔ) typical. Each regulator exhibits approximately
32 碌Vrms of output voltage noise with V
OUT
= 2.8 V
and a 0.01 碌F noise reduction (NR) capacitor. Appli-
cations with
analog components
that
are
noise-sensitive, such as portable RF electronics, will
benefit from high PSRR, low noise, and fast line and
load transient features. The TPS713xx family is
offered in a thin 3mm x 3mm SON package and is
fully specified from -40擄C to +125擄C (T
J
).
