•
•
•
•
The TL720M05-Q1 devices are monolithic integrated
low-dropout voltage regulators offered in 3-pin TO
packages. They regulate an input voltage up to 45 V
to VOUT of 5 V with 2% tolerance. The devices can
drive loads up to 450 mA and are short-circuit proof.
At overtemperature, the incorporated temperature
protection turns off the TL720M05-Q1 devices.

Qualified for Automotive Applications
Output Voltage of 5 V ±2%
Very Low Current Consumption
Very Low Dropout Voltage
Short-Circuit Protection
Reverse-Polarity Protection
ESD Protection > 6 kV
The input capacitor (CIN) compensates for line
fluctuation. Using a resistor of approximately 1 Ω in
series with CIN dampens the oscillation of input
inductivity and input capacitance. The output
capacitor (COUT) stabilizes the regulation circuit.
Output is stable at COUT ≥ 22 μF and ESR ≤ 5 Ω,
within the operating temperature range.

Qualified for Automotive Applications
Cluster
Body Control Modules
The control amplifier compares a reference voltage to
a voltage that is proportional to the output voltage
and drives the base of the series transistor through a
buffer. Saturation control as a function of the load
current prevents any oversaturation of the power
element. The device also incorporates a number of
internal circuits for protection against:
• Overload
• Overtemperature
• Reverse polarity

8 Detailed Description
8.1 Overview
The TL720M05-Q1 device is a monolithic integrated low-dropout voltage regulator offered in a 3-pin TO package.
The device regulates an input voltage up to 45 V to VOUT = 5 V (typical) with 2% tolerance. The device can
drive loads up to 450 mA and is short-circuit proof. At overtemperature, the incorporated temperature protection
turns off the device.

8.3 Feature Description
8.3.1 Regulated Output (OUT)
The OUT terminal is the regulated 5-V output. The control amplifier compares a reference voltage to a voltage
that is proportional to the output voltage and drives the base of the series transistor through a buffer. Saturation
control as a function of the load current prevents any oversaturation of the power element. The output has
current limitation. In the event that the regulator drops out of regulation, the output tracks the input minus a drop
based on the load current.
8.4 Device Functional Modes
8.4.1 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 and switch resistance. This allows for a smaller input capacitor and can possibly
eliminate the need of using a boost convertor during cold-crank conditions.

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
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 prevent a reset from occurring. TI recommends a low-ESR
ceramic capacitor with a dielectric of type X5R or X7R for better load transient response.
9.2 Typical Application
Figure 14 shows typical application circuits for the TL720M05-Q1 device.

9.2.2 Detailed Design Procedure
To
•
•
•
•
begin the design process, determine the following:
Input voltage range
Output voltage
Output current rating
Output capacitor
9.2.2.1 Thermal Consideration
Calculate the power dissipated by the device according to the following formula:
PT = IO × (VI – VO) + VI x IQ
where
•
•
•
•
PT = Total power dissipation of the device.
IO = output current
VI = input voltage
VO = output voltage
(1)
After determining the power dissipated by the device, calculate the junction temperature from the ambient
temperature and the device thermal impedance.
TJ = TA + RθJA x PT

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 device, TI recommends
adding an electrolytic capacitor with a value of 47 μF and a ceramic bypass at the input.
11 Layout
11.1 Layout Guidelines
Do not place any of the capacitors on the opposite side of the PCB from where the regulator is installed. The use
of vias and long traces is strongly discouraged because of the negative impact on system performance. Vias and
long traces can also cause instability.
Equivalent series inductance (ESL) and ESR must be minimized to maximize performance and ensure stability.
Every capacitor must be placed as close to the device as possible and on the same side of the PCB as the
regulator.
