description

The TPS71xx integrated circuits are a family
of micropower low-dropout (LDO) voltage
regulators. An order of magnitude reduction in
dropout voltage and quiescent current over
conventional LDO performance is achieved by
replacing the typical pnp pass transistor with a
PMOS device.

NC – No internal connection
SENSE – Fixed voltage options only
(TPS7133, TPS7148, and TPS7150)
FB – Adjustable version only (TPS7101)
†
‡
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (maximum of 32
mV at an output current of 100 mA for the TPS7150) and is directly proportional to the output current (see
Figure 1). Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very
low and remains independent of output loading (typically 285 µA over the full range of output current, 0 mA to
500 mA). These two key specifications yield a significant improvement in operating life for battery-powered
systems. The LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down
the regulator, reducing the quiescent current to 0.5 µA maximum at T = 25°C.

Power good (PG) reports low output voltage and can be used to implement a power-on reset or a low-battery
indicator.
The TPS71xx is offered in 3.3-V, 4.85-V, and 5-V fixed-voltage versions and in an adjustable version
(programmable over the range of 1.2 V to 9.75 V). Output voltage tolerance is specified as a maximum of 2%
over line, load, and temperature ranges (3% for adjustable version). The TPS71xx family is available in PDIP
(8 pin), SO (8 pin), and TSSOP (20-pin) packages. The TSSOP has a maximum height of 1.2 mm.

O
Output voltage programmed to 2.5 V with closed-loop configuration (see application information).
NOTES: 1. When V < 2.9 V and I > 150 mA simultaneously, pass element r
increases (see Figure 27) to a point such that the resulting
I
O
DS(on)
dropout voltage prevents the regulator from maintaining the specified tolerance range.
2. To calculate dropout voltage, use equation:
V
DO

r
O
DS(on)
r
is a function of both output current and input voltage. The parametric table lists r
for V = 2.4 V, 2.9 V, 3.9 V, and
I
DS(on)
DS(on)
5.9 V, which corresponds to dropout conditions for programmed output voltages of 2.5 V, 3 V, 4 V, and 6 V, respectively. For other
programmed values, refer to Figure 26.

SLVS092F – NOVEMBER 1994 – REVISED JANUARY 1997
APPLICATION INFORMATION
The TPS71xx series of low-dropout (LDO) regulators is designed to overcome many of the shortcomings of
earlier-generation LDOs, while adding features such as a power-saving shutdown mode and a power-good
indicator. The TPS71xx family includes three fixed-output voltage regulators: the TPS7133 (3.3 V), the
TPS7148(4.85V), andtheTPS7150(5V). Thefamilyalsooffersanadjustabledevice, theTPS7101(adjustable
from 1.2 V to 9.75 V).
device operation
The TPS71xx, unlike many other LDOs, features very low quiescent currents that remain virtually constant even
with varying loads. Conventional LDO regulators use a pnp-pass element, the base current of which is directly
proportional to the load current through the regulator (I = I /β). Close examination of the data sheets reveals
B
C
that those devices are typically specified under near no-load conditions; actual operating currents are much
higher as evidenced by typical quiescent current versus load current curves. The TPS71xx uses a PMOS
transistor to pass current; because the gate of the PMOS element is voltage driven, operating currents are low
and invariable over the full load range. The TPS71xx specifications reflect actual performance under load.
Another pitfall associated with the pnp-pass element is its tendency to saturate when the device goes into
dropout. The resulting drop in β forces an increase in I to maintain the load. During power up, this translates
B
to large start-up currents. Systems with limited supply current may fail to start up. In battery-powered systems,
it means rapid battery discharge when the voltage decays below the minimum required for regulation. The
TPS71xx quiescent current remains low even when the regulator drops out, eliminating both problems.
Included in the TPS71xx family is a 4.85-V regulator, the TPS7148. Designed specifically for 5-V cellular
systems, its 4.85-V output, regulated to within ± 2%, allows for operation within the low-end limit of 5-V systems
specified to ± 5% tolerance; therefore, maximum regulated operating lifetime is obtained from a battery pack
before the device drops out, adding crucial talk minutes between charges.
The TPS71xx family also features a shutdown mode that places the output in the high-impedance state
(essentially equal to the feedback-divider resistance) and reduces quiescent current to under 2 µA. If the
shutdown feature is not used, EN should be tied to ground. Response to an enable transition is quick; regulated
output voltage is reestablished in typically 120 µs.
minimum load requirements
The TPS71xx family is stable even at zero load; no minimum load is required for operation.
SENSE-pin connection
The SENSE pin of fixed-output devices must be connected to the regulator output for proper functioning of the
regulator. Normally, this connection should be as short as possible; however, the connection can be made near
a critical circuit (remote sense) to improve performance at that point. Internally, SENSE connects to a
high-impedance wide-bandwidth amplifier through a resistor-divider network and noise pickup feeds through
to the regulator output. Routing the SENSE connection to minimize/avoid noise pickup is essential. Adding an
RC network between SENSE and OUT to filter noise is not recommended because it can cause the regulator
to oscillate.
external capacitor requirements
An input capacitor is not required; however, a ceramic bypass capacitor (0.047 pF to 0.1 µF) improves load
transient response and noise rejection if the TPS71xx is located more than a few inches from the power supply.
A higher-capacitance electrolytic capacitor may be necessary if large (hundreds of milliamps) load transients
with fast rise times are anticipated.

APPLICATION INFORMATION
external capacitor requirements (continued)
As with most LDO regulators, the TPS71xx family requires an output capacitor for stability. A low-ESR 10-µF
solid-tantalum capacitor connected from the regulator output to ground is sufficient to ensure stability over the
full load range (see Figure 43). Adding high-frequency ceramic or film capacitors (such as power-supply bypass
capacitors for digital or analog ICs) can cause the regulator to become unstable unless the ESR of the tantalum
capacitor is less than 1.2 Ω over temperature. Capacitors with published ESR specifications such as the
AVX TPSD106K035R0300 and the Sprague 593D106X0035D2W work well because the maximum ESR at
25°C is 300 mΩ (typically, the ESR in solid-tantalum capacitors increases by a factor of 2 or less when the
temperature drops from 25°C to –40°C). Where component height and/or mounting area is a problem,
physically smaller, 10-µF devices can be screened for ESR. Figures 34 through 41 show the stable regions of
operation using different values of output capacitance with various values of ceramic load capacitance.
In applications with little or no high-frequency bypass capacitance (< 0.2 µF), the output capacitance can be
reduced to 4.7 µF, provided ESR is maintained between 0.7 and 2.5 Ω. Because minimum capacitor ESR is
seldom if ever specified, it may be necessary to add a 0.5-Ω to 1-Ω resistor in series with the capacitor and limit
ESR to 1.5 Ω maximum. As show in the ESR graphs (Figures 34 through 41), minimum ESR is not a problem
when using 10-µF or larger output capacitors.
Below is a partial listing of surface-mount capacitors usable with the TPS71xx family. This information (along
with the ESR graphs, Figures 34 through 41) is included to assist in selection of suitable capacitance for the
user’s application. When necessary to achieve low height requirements along with high output current and/or
high ceramic load capacitance, several higher ESR capacitors can be used in parallel to meet the guidelines
above.

Resistors R1 and R2 should be chosen for approximately 7-µA divider current. A recommended value for R2
is 169 kΩ with R1 adjusted for the desired output voltage. Smaller resistors can be used, but offer no inherent
advantage and consume more power. Larger values of R1 and R2 should be avoided as leakage currents at
FB will introduce an error. Solving equation 1 for R1 yields a more useful equation for choosing the appropriate

power-good indicator
The TPS71xx features a power-good (PG) output that can be used to monitor the status of the regulator. The
internal comparator monitors the output voltage: when the output drops to between 92% and 98% of its nominal
regulated value, the PG output transistor turns on, taking the signal low. The open-drain output requires a pullup
resistor. If not used, it can be left floating. PG can be used to drive power-on reset circuitry or as a low-battery
indicator. PG does not assert itself when the regulated output voltage falls outside the specified 2% tolerance,
but instead reports an output voltage low, relative to its nominal regulated value.
regulator protection
The TPS71xx PMOS-pass transistor has a built-in back diode that safely conducts reverse currents when the
input voltage drops below the output voltage (e.g., during power down). Current is conducted from the output
to the input and is not internally limited. When extended reverse voltage is anticipated, external limiting may be
appropriate.
The TPS71xx also features internal current limiting and thermal protection. During normal operation, the
TPS71xx limits output current to approximately 1 A. When current limiting engages, the output voltage scales
back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device
failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of
the device exceeds 165°C, thermal-protection circuitry shuts it down. Once the device has cooled, regulator
operation resumes.
