FEATURES
DESCRIPTION
•
•
•
•
•
•
The TPS714xx low-dropout (LDO) voltage regulators
offer the benefits of wide input voltage range,
low-dropout voltage, low-power operation, and
miniaturized packaging. These devices, which
operate over an input range of 2.5V to 10V, are
stable with any capacitor ≥ 0.47μF. The 2.5V to 10V
input voltage range, combined with 3.2μA quiescent
current, makes this device particularly well-suited for
two-cell alkaline, and two-cell lithium, and other low
quiescent current sensitive battery applications. The
low dropout voltage and low quiescent current allow
operation at extremely low power levels. Therefore,
the devices are ideal for power battery management
ICs. Specifically, because the device is enabled as
soon as the applied voltage reaches the minimum
input voltage, the output is quickly available to power
continuously-operating, battery-charging ICs.

APPLICATIONS
•
•
•
•
The typical PNP pass transistor has been replaced by
a PMOS pass element. Because the PMOS pass
element behaves as a low-value resistor, the low
dropout voltage (typically 415mV at 50mA of load
current) is directly proportional to the load current.
The quiescent current (3.2μA, typical) is stable over
the entire range of the output load current (0mA to
80mA).

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 TPS714xx family of LDO regulators has been optimized for ultralow power applications such as the MSP430
microcontroller. Its ultralow supply current maximizes efficiency at light loads, and its high input voltage range
makes it suitable for supplies such as unconditioned solar panels.

Figure 15. Typical Application Circuit (Fixed Voltage Version)
External Capacitor Requirements
Although not required, a 0.047μF or larger input bypass capacitor, connected between IN and GND and located
close to the device, is recommended to improve transient response and noise rejection of the power supply as a
whole. A higher-value input capacitor may be necessary if large, fast-rise-time load transients are anticipated and
if the device is located several inches from the power source.
The TPS714xx requires an output capacitor connected between OUT and GND to stabilize the internal control
loop. Any capacitor (including ceramic and tantalum) that is greater than or equal to 0.47μF properly stabilizes
this loop.
Power Dissipation and Junction Temperature
To ensure reliable operation, worst-case junction temperature should not exceed +125°C. This restriction limits
the power dissipation that the regulator can manage in any given application. To ensure the junction temperature
is within acceptable limits, calculate the maximum allowable dissipation, PD(MAX), and the actual dissipation, PD,
which must be less than or equal to PD(max).
The maximum-power-dissipation limit is determined using Equation 1:
T max * T A
P D(max) + J
R qJA
Where:
•
•
•
TJmax is the maximum allowable junction temperature.
RθJA is the thermal resistance junction-to-ambient for the package (see the Power Dissipation Rating table).
TA is the ambient temperature.
(1)
The regulator dissipation is calculated using Equation 2:
P D + ǒVIN * VOUTǓ
I OUT
(2)
Power dissipation resulting from quiescent current is negligible.
Regulator Protection
The TPS714xx PMOS-pass transistor has a built-in back diode that conducts reverse current when the input
voltage drops below the output voltage (for example, during power-down). Current is conducted from the output
to the input and is not internally limited. If extended reverse voltage operation is anticipated, external limiting
might be appropriate.
The TPS714xx features internal current limiting. During normal operation, the TPS714xx limits output current to
approximately 500mA. When current limiting engages, the output voltage scales back linearly until the
over-current condition ends. There is no internal thermal shutdown circuit in this device; therefore, care must be
taken not to exceed the power dissipation ratings of the package during a fault condition. This device does not
have undervoltage lockout; therefore, this constraint should be taken into consideration for specific applications.

Programming the TPS71401 Adjustable LDO Regulator
The output voltage of the TPS71401 adjustable regulator is programmed using an external resistor divider as
shown in Figure 16. The output voltage is calculated using Equation 3:
V OUT + VREF
Ǔ
ǒ1 ) R1
R2
(3)
where:
VREF = 1.20V typ (the internal reference voltage)
Resistors R1 and R2 should be chosen for approximately a 1.5μA divider current. Lower value resistors can be
used for improved noise performance, but the solution consumes more power. Higher resistor values should be
avoided because leakage current out of the FB pin across R1/R2 creates an offset voltage that artificially
increases the feedback voltage and thus erroneously decreases VOUT. The recommended design procedure is to
choose R2 = 1MΩ to set the divider current at 1.5μA, and then calculate R1 using Equation 4:
