Dual, 200mA Output, Low Noise, High PSRR
Low-Dropout Linear Regulators in 2mm x 2mm SON Package
FEATURES
DESCRIPTION
•
Dual, 200mA High-Performance LDOs
The TPS718xx and TPS719xx families of
low-dropout (LDO) regulators offer high
a
•
Low Total Quiescent Current: 90µA with Both
power-supply rejection ratio (PSRR), low noise, fast
start-up, and excellent line and load transient
responses while consuming a very low 90µA (typical)
at no load ground current with both LDOs enabled.
The TPS719xx also provides an active pulldown
circuit to quickly discharge output loads. The
TPS718xx and TPS719xx are stable with ceramic
capacitors and use an advanced BiCMOS fabrication
process to yield a typical dropout voltage of 230mV
at 200mA output loads. The TPS718xx and
TPS719xx also use a precision voltage reference
and feedback loop to achieve 3% overall accuracy
over all load, line, process, and temperature
variations. Both families of devices are fully specified
from TJ = –40°C to +125°C and are offered in a 2mm
× 2mm SON-6 package that is ideal for applications
such as mobile handsets and WLAN that require
good thermal dissipation while maintaining a very
small footprint.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.

APPLICATION INFORMATION
The TPS718xx/TPS719xx belong to a family of new
generation LDO regulators that use innovative
circuitry to achieve ultra-wide bandwidth and high
loop gain, resulting in extremely high PSRR (up to
1MHz) at very low headroom (VIN – VOUT). These
features, combined with low noise, two independent
enables, low ground pin current and ultra-small
packaging, make this part ideal for portable
applications. This family of regulators offer
sub-bandgap output voltages, current limit and
thermal protection, and is fully specified from –40°C
to +125°C.
Board Layout Recommendations to Improve
PSRR and Noise Performance
To improve ac performance such as PSRR, output
noise, and transient response, it is recommended
that the board be designed with separate ground
planes for VIN and VOUT, with each ground plane
connected only at the GND pin of the device. In
addition, the ground connection for the output
capacitor should connect directly to the GND pin of
the device. High ESR capacitors may degrade
PSRR.
Figure 22 shows the basic circuit connections.
Internal Current Limit
2.7V - 6.5V
0.9V - 3.6V
1mF
The TPS718xx/TPS719xx internal current limits help
protect the regulator during fault conditions. During
current limit, the output sources a fixed amount of
current that is largely independent of output voltage.
For reliable operation, the device should not be
operated in a current limit state for extended periods
of time.

TPS718xx/TPS719xx has a built-in body diode that
conducts current when the voltage at OUT exceeds
the voltage at IN. This current is not limited, so if
extended reverse voltage operation is anticipated,
external limiting to 5% of rated output current may be
appropriate.
Figure 22. Typical Application Circuit
Input and Output Capacitor Requirements
Shutdown
Although an input capacitor is not required for
stability, it is good analog design practice to connect
a 0.1µF to 1.0µF low equivalent series resistance
(ESR) capacitor across the input supply near the
regulator. This capacitor counteracts reactive input
sources and improves transient response, noise
The enable pin (EN) is active high and is compatible
with standard and low voltage, TTL-CMOS levels.
When shutdown capability is not required, EN can be
connected to IN. The TPS719 with internal active
output pulldown circuitry discharges the output with a
time constant (t) of:
rejection, and ripple rejection.
A
higher-value
capacitor may be necessary if large, fast rise-time
load transients are anticipated or if the device is
located close to the power source. If source
impedance is not sufficiently low, a 0.1µF input
capacitor may be necessary to ensure stability.
60 ´ RL
´ COUT
t = 3
60 + RL
with:
•
RL = output load resistance
COUT = Output capacitance
The TPS718xx/TPS719xx are designed to be stable
with standard ceramic capacitors of values 1.0µF or
larger at the output. X5R- and X7R-type capacitors
are best because they have minimal variation in
value and ESR over temperature. Maximum ESR
should be <1.0Ω.
•
Dropout Voltage
The TPS718xx/TPS719xx use
transistor to achieve low dropout. When (VIN – VOUT
a
PMOS pass
)
is less than the dropout voltage (VDO), the PMOS
pass device is in its linear region of operation and
the input-to-output resistance is the RDS(ON) of the
PMOS pass element. VDO approximately scales with
output current because the PMOS device behaves
like a resistor in dropout.

As with any linear regulator, PSRR and transient
response are degraded as (VIN – VOUT) approaches
dropout. This effect is shown in Figure 13 and
Figure 14 in the Typical Characteristics section.

circuit indicates excessive power dissipation or an
inadequate heatsink. For reliable operation, junction
temperature should be limited to +125°C maximum.
To estimate the margin of safety in a complete
design (including heatsink), increase the ambient
temperature until the thermal protection is triggered;
use worst-case loads and signal conditions. For good
reliability, thermal protection should trigger at least
+35°C above the maximum expected ambient
condition of your particular application. This

As with any regulator, increasing the size of the
output capacitor will reduce over/undershoot

Under-Voltage Lock-Out (UVLO)
ambient temperature and worst-case load.
The TPS718xx/TPS719xx utilize an under-voltage
lock-out circuit to keep the output shut off until
internal circuitry is operating properly. The UVLO
circuit has a de-glitch feature so that it typically
ignores undershoot transients on the input if they are
less than 50µs duration. On the TPS719xx, the
active pulldown discharges VOUT when the device is
in UVLO off condition. However, the input voltage
needs to be greater than 0.8V for active pulldown to
work.
The

of
the
TPS718xx/TPS719xx has been designed to protect
against overload conditions. It was not intended to
replace proper heatsinking. Continuously running the
TPS718xx/TPS719xx
into

degrades device reliability.
Power Dissipation
The ability to remove heat from the die is different for
each package type, presenting different
Minimum Load
considerations in the printed circuit board (PCB)
layout. The PCB area around the device that is free
of other components moves the heat from the device
to the ambient air. Performance data for JEDEC low-
and high-K boards are given in the Dissipation
Ratings table. Using heavier copper increases the
effectiveness in removing heat from the device. The
addition of plated through-holes to heat-dissipating
layers also improves the heatsink effectiveness.
The TPS718xx/TPS719xx are stable with no output
load. Traditional PMOS LDO regulators suffer from
lower loop gain at very light output loads. The
TPS718xx/TPS719xx
employ
an
innovative,
low-current mode circuit under very light or no-load
conditions, resulting in improved output voltage
regulation performance down to zero output current.
THERMAL INFORMATION
Thermal Protection
Power dissipation depends on input voltage and load
conditions. Power dissipation (PD) is equal to the
product of the output current times the voltage drop
across the output pass element (VIN to VOUT), as
shown in Equation 1:
Thermal protection disables the output when the
junction temperature rises to approximately +160°C,
allowing the device to cool. When the junction
temperature cools to approximately +140°C the
output circuitry is again enabled. Depending on
power dissipation, thermal resistance, and ambient
temperature, the thermal protection circuit may cycle
on and off. This cycling limits the dissipation of the
regulator, protecting it from damage due to
overheating.
PD = (VIN - VOUT) x IOUT
