8 Detailed Description
8.1 Overview
The TPS7B69xx-Q1 high-voltage linear regulator operates over a 4-V to 40-V input voltage range. The device
has an output current capability of 150 mA and offers fixed output voltages of 2.5 V (TPS7B6925-Q1), 3.3 V
(TPS7B6933-Q1) or 5 V (TPS7B6950-Q1). The device features a thermal shutdown and short-circuit protection
to prevent damage during over-temperature and overcurrent conditions.

8.3 Feature Description
8.3.1 Input (IN)
The IN pin is a high-voltage-tolerant pin. A capacitor with a value higher than 0.1 µF is recommended to be
connected close to this pin to better the transient performance.
8.3.2 Output (OUT)
The OUT pin is the regulated output based on the required voltage. The output has current limitation. During the
initial power up, the regulator has a soft start incorporated to control the initial current through the pass element
and the output capacitor.
In the event that the regulator drops out of regulation, the output tracks the input minus a drop based on the load
current. When the input voltage drops below the UVLO threshold, the regulator shuts down until the input voltage
recovers above the minimum startup level.
8.3.3 Output Capacitor Selection
For stable operation over the full temperature range and with load currents up to 150 mA, use a capacitor with an
effective value between 2.2 µF and 100 µF and ESR smaller than 2 Ω. To better the load transient performance,
an output capacitor, such as a ceramic capacitor with low ESR, is recommended.
8.3.4 Low-Voltage Tracking
At low input voltages, the regulator drops out of regulation and the output voltage tracks input minus a voltage
based on the load current (IL) and switch resistor. This tracking allows for a smaller input capacitor and can
possibly eliminate the need for a boost converter during cold-crank conditions.

Feature Description (continued)
8.3.5 Thermal Shutdown
The TPS7B69xx-Q1 family of devices incorporates a thermal-shutdown (TSD) circuit as a protection from
overheating. For continuous normal operation, the junction temperature should not exceed the TSD trip point. If
the junction temperature exceeds the TSD trip point, the output turns off. When the junction temperature falls
below the TSD trip point minus the hysteresis of TSD, the output turns on again. This cycling limits the
dissipation of the regulator, protecting it from damage as a result of overheating.
The purpose of the design of the internal protection circuitry of the TPS7B69xx-Q1 family of devices is for
protection against overload conditions, not as a replacement for proper heat-sinking. Continuously running the
TPS7B69xx-Q1 family of devices into thermal shutdown degrades device reliability.
8.4 Device Functional Modes
8.4.1 Operation With VI Less Than 4 V
The TPS7B69xx-Q1 family of devices operates with input voltages above 4 V. The maximum UVLO voltage is 3
V and the device operates at an input voltage above 4 V. The device can also operate at lower input voltages; no
minimum UVLO voltage is specified. At input voltages below the actual UVLO, the device shuts down.
8.4.2 Operation With VI Greater Than 4 V
When VI is greater than 4 V, if the input voltage is higher than VO plus the dropout voltage, the output voltage is
equal to the set value. Otherwise, the output voltage is equal to VI minus the dropout voltage.

9 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. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The TPS7B69xx-Q1 family of devices is a 150-mA low-dropout linear regulator designed for up to 40-V VI
operation with only 15-µA quiescent current at light loads. Use the PSpice transient model to evaluate the base
function of the device. To download the PSpice transient model, go to the device product folder on www.TI.com.
In addition to this model, specific evaluation modules (EVM) are available for these devices. For the EVM and
the EVM user guide, go to the device product folder.
9.2 Typical Application
Figure 25 shows the typical application circuit for the TPS7B69xx-Q1 family of devices. Based on the end-
application, different values of external components can be used. An application can require a larger output
capacitor during fast load steps to achieve better load transient response. TI recommends a low-ESR ceramic
capacitor with a dielectric of type X5R or X7R for better load transient response.

9.2.2.1 Input Capacitor
The device requires an input decoupling capacitor, the value of which depends on the application. The typical
recommend value for the decoupling capacitor is higher than 0.1 µF. The voltage rating must be greater than the
maximum input voltage.
9.2.2.2 Output Capacitor
The device requires an output capacitor to stabilize the output voltage. The output capacitor value should be
between 2.2 µF and 100 µF. The ESR value range should be between 1 mΩ and 2 Ω. TI recommends a ceramic
capacitor with low ESR to improve the load transient response.
9.2.2.3 Power Dissipation and Thermal Considerations
Use Equation 1 to calculate the power dissipated in the device.
PD = IO × (VI – VO) + IQ × VI
where
•
•
•
•
PD = continuous power dissipation
IO = output current
VI = input voltage
VO = output voltage
(1)
Because IQ « IO, the term IQ × VI in Equation 1 can be ignored.
For a device under operation at a given ambient air temperature (TA), use Equation 2 to calculate the junction
temperature (TJ).
TJ = TA + (ZθJA × PD)
where
•
Z
θJA = junction-to-ambient air thermal impedance
(2)
(3)
Use Equation 3 to calculate the rise in junction temperature because of power dissipation.
ΔT = TJ – TA = (ZθJA × PD)
For a given maximum junction temperature (TJmax), use Equation 4 to calculate the maximum ambient air
temperature (TAmax) at which the device can operate.
TAmax = TJmax – (ZθJA × PD)

10 Power Supply Recommendations
The device is designed to operate from an input-voltage supply range between 4 V and 40 V. This input supply
must be well regulated. If the input supply is located more than a few inches from the TPS7B69xx-Q1 device, TI
recommends adding an electrolytic capacitor with a value of 10 µF and a ceramic bypass capacitor at the input.
11 Layout
11.1 Layout Guidelines
For the layout of TPS7B69xx-Q1 family of devices, place the input and output capacitors close to the devices as
shown in Figure 27 and Figure 28. To enhance the thermal performance, TI recommends surrounding the device
with some vias.
Minimize equivalent series inductance (ESL) and ESR to maximize performance and ensure stability. Place
every capacitor as close as possible to the device and on the same side of the PCB as the regulator.
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 long traces because they can impact system performance negatively and even
cause instability.
If possible, and to ensure the maximum performance specified in this product data sheet, use the same layout
pattern used for the TPS7B69xx-Q1 evaluation board.
