7 Detailed Description
7.1 Overview
The TPS7B83-Q1 is a low-dropout linear regulator (LDO) designed to connect to the battery in automotive
applications. The device has an input voltage range extending to 40 V, which allows the device to withstand
transients (such as load dumps) that are anticipated in automotive systems. With only a 18-µA quiescent current
at light loads, the device is an optimal solution for powering always-on components.
The device has a state-of-the-art transient response that allows the output to quickly react to changes in the load
or line (for example, during cold-crank conditions). Additionally, the device has a novel architecture that
minimizes output overshoot when recovering from dropout. During normal operation, the device has a tight DC
accuracy of ±1% over line, load, and temperature.

7.3 Feature Description
7.3.1 Undervoltage Lockout
The device has an independent undervoltage lockout (UVLO) circuit that monitors the input voltage, allowing a
controlled and consistent turn on and off of the output voltage. To prevent the device from turning off if the input
drops during turn on, the UVLO has hysteresis as specified in the Electrical Characteristics table.
7.3.2 Thermal Shutdown
The device contains a thermal shutdown protection circuit to disable the device when the junction temperature
(TJ) of the pass transistor rises to TSD(shutdown) (typical). Thermal shutdown hysteresis assures that the device
resets (turns on) when the temperature falls to TSD(reset) (typical).
The thermal time-constant of the semiconductor die is fairly short, thus the device may cycle on and off when
thermal shutdown is reached until power dissipation is reduced. Power dissipation during startup can be high
from large VIN – VOUT voltage drops across the device or from high inrush currents charging large output
capacitors. Under some conditions, the thermal shutdown protection disables the device before startup
completes.
For reliable operation, limit the junction temperature to the maximum listed in the Recommended Operating
Conditions table. Operation above this maximum temperature causes the device to exceed its operational
specifications. Although the internal protection circuitry of the device is designed to protect against thermal
overall conditions, this circuitry is not intended to replace proper heat sinking. Continuously running the device
into thermal shutdown or above the maximum recommended junction temperature reduces long-term reliability.
7.3.3 Current Limit
The device has an internal current limit circuit that protects the regulator during transient high-load current faults
or shorting events. The current limit is a brickwall scheme. In a high-load current fault, the brickwall scheme
limits the output current to the current limit (ICL). ICL is listed in the Electrical Characteristics table.
The output voltage is not regulated when the device is in current limit. When a current limit event occurs, the
device begins to heat up because of the increase in power dissipation. When the device is in brickwall current
limit, the pass transistor dissipates power [(VIN – VOUT) × ICL]. If thermal shutdown is triggered, the device turns
off. After the device cools down, the internal thermal shutdown circuit turns the device back on. If the output
current fault condition continues, the device cycles between current limit and thermal shutdown. For more
information on current limits, see the Know Your Limits application report.

7.4.2 Normal Operation
The device regulates to the nominal output voltage when the following conditions are met:
• The input voltage is greater than the nominal output voltage plus the dropout voltage (VOUT(nom) + VDO
)
• The output current is less than the current limit (IOUT < ICL)
• The device junction temperature is less than the thermal shutdown temperature (TJ < TSD
)
• The enable voltage has previously exceeded the enable rising threshold voltage and has not yet decreased
to less than the enable falling threshold
7.4.3 Dropout Operation
If the input voltage is lower than the nominal output voltage plus the specified dropout voltage, but all other
conditions are met for normal operation, the device operates in dropout mode. In this mode, the output voltage
tracks the input voltage. During this mode, the transient performance of the device becomes significantly
degraded because the pass transistor is in the ohmic or triode region, and acts as a switch. Line or load
transients in dropout can result in large output-voltage deviations.
When the device is in a steady dropout state (defined as when the device is in dropout, VIN < VOUT(NOM) + VDO
,
directly after being in a normal regulation state, but not during startup), the pass transistor is driven into the
ohmic or triode region. When the input voltage returns to a value greater than or equal to the nominal output
voltage plus the dropout voltage (VOUT(NOM) + VDO), the output voltage can overshoot for a short period of time
while the device pulls the pass transistor back into the linear region.

8 Application and Implementation
Note
以下应用部分的信息不属于 TI 组件规范,TI 不担保其准确性和完整性。客户应负责确定 TI 组件是否适
用于其应用。客户应验证并测试其设计,以确保系统功能。
8.1 Application Information
8.1.1 Input and Output Capacitor Selection
The TPS7B83-Q1 requires an output capacitor of 2.2 µF or larger (1 µF or larger capacitance) for stability and an
equivalent series resistance (ESR) between 0.001 Ω and 2 Ω. For the best transient performance, use X5R-
and X7R-type ceramic capacitors because these capacitors have minimal variation in value and ESR over
temperature. When choosing a capacitor for a specific application, be mindful of the DC bias characteristics for
the capacitor. Higher output voltages cause a significant derating of the capacitor. For best performance, the
maximum recommended output capacitance is 220 µF.
Although an input capacitor is not required for stability, good analog design practice is to connect a capacitor
from IN to GND. Some input supplies have a high impedance, thus placing the input capacitor on the input
supply helps reduce the input impedance. This capacitor counteracts reactive input sources and improves
transient response, input ripple, and PSRR. If the input supply has a high impedance over a large range of
frequencies, several input capacitors can be used in parallel to lower the impedance over frequency. Use a
higher-value capacitor if large, fast, rise-time load transients are anticipated, or if the device is located several
inches from the input power source.
8.1.2 Dropout Voltage
Dropout voltage (VDO) is defined as the input voltage minus the output voltage (VIN – VOUT) at the rated output
current (IRATED), where the pass transistor is fully on. IRATED is the maximum IOUT listed in the Recommended
Operating Conditions table. The pass transistor is in the ohmic or triode region of operation, and acts as a
switch. The dropout voltage indirectly specifies a minimum input voltage greater than the nominal programmed
output voltage at which the output voltage is expected to stay in regulation. If the input voltage falls to less than
the nominal output regulation, then the output voltage falls as well.
For a CMOS regulator, the dropout voltage is determined by the drain-source on-state resistance (RDS(ON)) of the
pass transistor. Therefore, if the linear regulator operates at less than the rated current, the dropout voltage for
that current scales accordingly. The following equation calculates the RDS(ON) of the device.
VDO
RDS(ON)
=
IRATED
(1)
8.1.3 Reverse Current
Excessive reverse current can damage this device. Reverse current flows through the intrinsic body diode of the
pass transistor instead of the normal conducting channel. At high magnitudes, this current flow degrades the
long-term reliability of the device.
Conditions where reverse current can occur are outlined in this section, all of which can exceed the absolute
maximum rating of VOUT ≤ VIN + 0.3 V.
• If the device has a large COUT and the input supply collapses with little or no load current
• The output is biased when the input supply is not established
• The output is biased above the input supply
If reverse current flow is expected in the application, external protection is recommended to protect the device.
Reverse current is not limited in the device, so external limiting is required if extended reverse voltage operation
is anticipated.

8.1.4 Power Dissipation (PD)
Circuit reliability requires consideration of the device power dissipation, location of the circuit on the printed
circuit board (PCB), and correct sizing of the thermal plane. The PCB area around the regulator must have few
or no other heat-generating devices that cause added thermal stress.
To first-order approximation, power dissipation in the regulator depends on the input-to-output voltage difference
and load conditions. The following equation calculates power dissipation (PD).
PD = (VIN – VOUT) × IOUT
(2)
Note
Power dissipation can be minimized, and therefore greater efficiency can be achieved, by correct
selection of the system voltage rails. For the lowest power dissipation use the minimum input voltage
required for correct output regulation.
For devices with a thermal pad, the primary heat conduction path for the device package is through the thermal
pad to the PCB. Solder the thermal pad to a copper pad area under the device. This pad area must contain an
array of plated vias that conduct heat to additional copper planes for increased heat dissipation.
The maximum power dissipation determines the maximum allowable ambient temperature (TA) for the device.
According to the following equation, power dissipation and junction temperature are most often related by the
junction-to-ambient thermal resistance (RθJA) of the combined PCB and device package and the temperature of
the ambient air (TA).
TJ = TA + (RθJA × PD)
(3)
Thermal resistance (RθJA) is highly dependent on the heat-spreading capability built into the particular PCB
design, and therefore varies according to the total copper area, copper weight, and location of the planes. The
junction-to-ambient thermal resistance listed in the Thermal Information table is determined by the JEDEC
standard PCB and copper-spreading area, and is used as a relative measure of package thermal performance.
8.1.4.1 Thermal Performance Versus Copper Area
The most used thermal resistance parameter, RθJA, is highly dependent on the heat-spreading capability built
into the particular PCB design, and therefore varies according to the total copper area, copper weight, and
location of the planes. The RθJA recorded in the Thermal Information table in the Specifications section is
determined by the JEDEC standard (see 图 8-1), PCB, and copper-spreading area, and is only used as a
relative measure of package thermal performance. For a well-designed thermal layout, RθJA is actually the sum
of the package junction-to-case (bottom) thermal resistance (RθJCbot) plus the thermal resistance contribution by
the PCB copper.

8.1.5 Estimating Junction Temperature
The JEDEC standard now recommends the use of psi (Ψ) thermal metrics to estimate the junction temperatures
of the linear regulator when in-circuit on a typical PCB board application. These metrics are not thermal
resistance parameters and instead offer a practical and relative way to estimate junction temperature. These psi
metrics are determined to be significantly independent of the copper area available for heat-spreading. The
Thermal Information table lists the primary thermal metrics, which are the junction-to-top characterization
parameter (ψJT) and junction-to-board characterization parameter (ψJB). These parameters provide two
methods for calculating the junction temperature (TJ), as described in the following equations. Use the junction-
to-top characterization parameter (ψJT) with the temperature at the center-top of device package (TT) to
calculate the junction temperature. Use the junction-to-board characterization parameter (ψJB) with the PCB
surface temperature 1 mm from the device package (TB) to calculate the junction temperature.
TJ = TT + ψJT × PD
(4)
where:
• PD is the dissipated power
• TT is the temperature at the center-top of the device package
TJ = TB + ψJB × PD
(5)
where
• TB is the PCB surface temperature measured 1 mm from the device package and centered on the package
edge
For detailed information on the thermal metrics and how to use them, see the Semiconductor and IC Package
Thermal Metrics application report.

The device requires an input decoupling capacitor, the value of which depends on the application. The typical
recommended value for the decoupling capacitor is 1 µF. The voltage rating must be greater than the maximum
input voltage.
8.2.2.2 Output Capacitor

9 Power Supply Recommendations
This device is designed for operation from an input voltage supply with a range between 3 V and 40 V. This input
supply must be well regulated. If the input supply is located more than a few inches from the TPS7B83-Q1, add
an electrolytic capacitor and a ceramic bypass capacitor at the input.

10 Layout
10.1 Layout Guidelines
For best overall performance, place all circuit components on the same side of the circuit board and as near as
practical to the respective LDO pin connections. Place ground return connections to the input and output
capacitor, and to the LDO ground pin as close as possible to each other, connected by a wide, component-side,
copper surface. The use of vias and long traces to the input and output capacitors is strongly discouraged and
negatively affects system performance. TI also recommends a ground reference plane either embedded in the
PCB itself or located on the bottom side of the PCB opposite the components. This reference plane serves to
assure accuracy of the output voltage, shield noise, and behaves similarly to a thermal plane to spread (or sink)
heat from the LDO device when connected to the thermal pad. In most applications, this ground plane is
necessary to meet thermal requirements.
10.1.1 Package Mounting
Solder pad footprint recommendations for the TPS7B83-Q1 are available at the end of this document and at
www.ti.com.
10.1.2 Board Layout Recommendations to Improve PSRR and Noise Performance
As depicted in 图 10-1, place the input and output capacitors close to the device for the layout of the TPS7B83-
Q1. In order to enhance the thermal performance, place as many vias as possible around the device. These vias
improve the heat transfer between the different GND planes in the PCB.
To improve ac performance such as PSRR, output noise, and transient response, TI recommends a board
design with separate ground planes for IN and OUT, with each ground plane connected only at the GND pin of
the device. In addition, the ground connection for the output capacitor must connect directly to the GND pin of
the device.
Minimize equivalent series inductance (ESL) and ESR in order to maximize performance and ensure stability.
Place each capacitor as close as possible to the device and on the same side of the PCB as the regulator itself.
Do not place any of the capacitors on the opposite side of the PCB from where the regulator is installed. TI
strongly discourages the use of vias and long traces to connect the capacitors because these can negatively
impact system performance and may even cause instability.
If possible, and to ensure the maximum performance specified in this document, use the same layout pattern
used for the TPS7B83-Q1 evaluation board, available at www.ti.com.
