TPS7B82-Q1 Automotive 300-mA, High-Voltage, Ultra-Low-IQ Low-Dropout Regulator
1 Features
3 Description
•
•
•
AEC-Q100 qualified for automotive applications:
– Temperature grade 1: –40°C ≤ TA ≤ 125°C
– Temperature grade 0: –40°C ≤ TA ≤ 150°C
Extended junction temperature range:
– Grade 1: –40°C ≤ TJ ≤ 150°C
– Grade 0: –40°C ≤ TJ ≤ 165°C
Low quiescent current IQ:
– 300-nA shutdown IQ
– 2.7 µA typical at light loads
– 5 µA maximum at light loads
3-V to 40-V wide VIN input voltage range with up to
45-V transient
In automotive battery-connected applications, low
quiescent current (IQ) is important to save power and
extend battery lifetime. Ultra-low IQ must be included
for always-on systems.
The TPS7B82-Q1 is a low-dropout linear regulator
designed to operate with a wide input-voltage range
from 3 V to 40 V (45-V load dump protection).
Operation down to 3 V allows the TPS7B82-Q1 to
continue operating during cold-crank and start and
stop conditions. With only 2.7-µA typical quiescent
current at light load, this device is an optimal solution
for powering microcontrollers (MCUs) and CAN/LIN
transceivers in standby systems.
•
•
•
•
Maximum output current: 300 mA
2% output-voltage accuracy
The device features integrated short-circuit and
overcurrent protection. This device operates in
ambient temperatures from –40°C to +125°C and
with junction temperatures from –40°C to +150°C.
Additionally, this device uses a thermally conductive
package to enable sustained operation despite
significant dissipation across the device. Because of
these features, the device is designed as a power
supply for various automotive applications.
Maximum dropout voltage: 700 mV at 200-mA load
current for fixed 5-V output version
Stable with low-ESR (0.001-Ω to 5-Ω) ceramic
output-stability capacitor (1 µF to 200 µF)
Fixed 2.5-V, 3.3-V, and 5-V output voltage
Packages:
– 8-pin HVSSOP, RθJA = 63.9°C/W
– 6-pin WSON, RθJA = 72.8°C/W
– 5-pin TO-252, RθJA = 31.1°C/W
– 14-pin HTSSOP, RθJA = 52.0°C/W

7 Detailed Description
7.1 Overview
The TPS7B82-Q1 is a 40-V, 300-mA low-dropout (LDO) linear regulator with ultra-low quiescent current. This
voltage regulator consumes only 3 μA of quiescent current at light load, and is designed for the automotive
always-on application.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 Device Enable (EN)
The EN pin is a high-voltage-tolerant pin. A high input activates the device and turns the regulation ON. Connect
this pin to an external microcontroller or a digital circuit to enable and disable the device, or connect to the IN pin
for self-bias applications.
7.3.2 Undervoltage Shutdown
This device has an integrated undervoltage lockout (UVLO) circuit to shut down the output if the input voltage
(VIN) falls below an internal UVLO threshold (V(UVLO)). This threshold limit ensures that the regulator does not
latch into an unknown state during low-input-voltage conditions. If the input voltage has a negative transient that
drops below the UVLO threshold and recovers, the regulator shuts down and powers up with a normal power-up
sequence when the input voltage is above the required level.
7.3.3 Current Limit
This device features current-limit protection to keep the device in a safe operating area when an overload
or output short-to-ground condition occurs. This limit protects the device from excessive power dissipation.
For example, during a short-circuit condition on the output, fault protection limits the current through the pass
element to I(LIM) to protect the device from excessive power dissipation.
7.3.4 Thermal Shutdown
This device incorporates a thermal shutdown (TSD) circuit as a protection from overheating. For continuous
normal operation, the junction temperature must not exceed the TSD trip point. The junction temperature
exceeding the TSD trip point causes the output to turn off. When the junction temperature falls below the TSD
trip point minus thermal shutdown hysteresis, the output turns on again.

7.4 Device Functional Modes
7.4.1 Operation With VIN Lower Than 3 V
The device normally operates with input voltages above 3 V. The device can also operate at lower input
voltages; the maximum UVLO voltage is 2.7 V. At input voltages below the actual UVLO voltage, the device does
not operate.
7.4.2 Operation With VIN Larger Than 3 V
When VIN is greater than 3 V, if VIN is also higher than the output set value plus the device dropout voltage, VOUT
is equal to the set value. Otherwise, VOUT is equal to VIN minus the dropout voltage.

8 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.
8.1 Application Information
The TPS7B82-Q1 is a 300-mA, 40-V low-dropout linear regulator with ultra-low quiescent current. The PSpice
transient model is available for download on the product folder and can be used to evaluate the basic function of
the device.
8.2 Typical Application
Figure 8-1 shows a typical application circuit for the TPS7B82-Q1. Different values of external components can
be used, depending on the end application. An application may require a larger output capacitor during fast load
steps to prevent a large drop on the output voltage. Use a low-ESR ceramic capacitor with a dielectric of type
X5R or X7R.

8.2.2.1 Input Capacitor
Although an input capacitor is not required for stability, good analog design practice is to connect a 10-µF to
22-µF capacitor from IN to GND. This capacitor counteracts reactive input sources and improves transient
response, input ripple rejection, and PSRR. The voltage rating must be greater than the maximum input voltage.
8.2.2.2 Output Capacitor
To ensure the stability of the TPS7B82-Q1, the device requires an output capacitor with a value in the range from
1 μF to 200 μF and with an ESR range between 0.001 Ω and 5 Ω. Select a ceramic capacitor with low ESR to
improve the load transient response.

9 Power Supply Recommendations
The device is designed to operate from an input voltage supply range from 3 V to 40 V. This input supply must
be well regulated. If the input supply is located more than a few inches from the TPS7B82-Q1, add a capacitor
with a value greater than or equal to 10 μF with a 0.1-μF bypass capacitor in parallel at the input.
10 Layout
10.1 Layout Guidelines
For LDO power supplies, especially high-voltage and large output current supplies, layout is an important step.
If layout is not carefully designed, the regulator can fail to deliver enough output current because of thermal
limitation. To improve the thermal performance of the device, and to maximize the current output at high ambient
temperature, spread the copper under the thermal pad as far as possible and place enough thermal vias on the
copper under the thermal pad. Figure 10-1 shows an example layout.
