Introduction
The TI TPS7A4700-094 Evaluation Module is designed to help engineers evaluate the operation and
performance of the TPS7A4700 linear regulator for possible use in their own circuit application. Notable
features of this LDO regulator include thermal and current limit shutdown protection, pin selectable output
voltage, low dropout, and low noise (~3.5 µV/√Hz). The EVM contains a single linear regulator in a 5 mm
× 5 mm, QFN (RGW), thermally enhanced ( PowerPad™) package. This regulator, including external
components, is capable of delivering up to 1.0 A to a dynamic load across the full recommended input and
output voltage range of the LDO. A multi-pin header with jumpers is provided to enable easy manual
selection of the output voltage.
PowerPad is a trademark of Texas Instruments.

Setup
This section describes the connectors and headers on the EVM as well as how to properly connect, setup
and use the TPS7A4700EVM-094. See the Assembly Layer diagram, Figure 5, for the location and
orientation of referenced components.

J4 GND – Ground return from the load (up to 1 Amp)
J5 (S+) – VOUT, Kelvin connection VOUT

J6 & J7 – Extra GRD connections
J8 – Enable jumper for external resistor divider
J9 – Enable jumper for the TPS7A4700-094 EVM
J10 – Header for selecting the appropriate output voltage
NOTE: The positive input lead and ground return lead from the input power supply should be twisted
and kept as short as possible to minimize EMI and source inductance. Additional bulk
capacitance in the form of a Tantalum cap (47 µF; 35 V) has been added to the EVM at C1
to counter source inductances that may cause ringing on the load transient waveform during
higher current transients. This bulk capacitance should not be necessary in a typical
application circuit.
Output Voltage Set Note: Set the output voltage by connecting J10 header pins, each
assigned to a given voltage level, to ground where VOUT = VREF + (Sum of the jumper
voltages). J10 header pins are numbered sequentially, odd pins (1, 3, 5...15) ascending
leftward of pin 1 on the top row. All odd pins are connected to ground. Each even pin is
numbered right to left sequentially (2, 4, 6…16) on the bottom row and each even pin is
assigned a unique voltage level. See the pin-to-pin output voltage assignments in Table 1.

Initial Setup and Equipment Interconnect
•

Select the desired VOUT by programming the output voltage according to the instructions listed above in
the Output Voltage Set Note in Section 2.1.
Disable the EVM by adding a shorting jumper to J9 from EN (Pin 2) to OFF (Pin3).
Before connecting the input power supply to the EVM, verify that the output voltage is set to the
desired supply voltage (+3 V to +35 V range) and that it is current limited to 2 A. With the input power
supply turned off, connect the positive voltage lead (+) from the power supply to VIN (J1, Pin 1) of the
EVM. Next, connect the ground lead (-) from the power supply to GND (J2, Pin 1).
Connect a 0- to 1-A load between VOUT (J3, Pin 1) and GND (J4, Pin 1).
Operation
1. Turn on the input power supply and verify that the output voltage, VOUT, is near 0 V.
2. Enable the output by reconnecting the jumper on J9 to short the EN (Pin 2) to the ON (Pin 1).
3. Vary the load current and VIN voltage as necessary for test purposes.
NOTE: Note: Power dissipation (PDISP) across the TPS7A4700 is dependent on the VIN to VOUT
voltage drop and the output load current, ILoad (PDISP = (VIN – VOUT) × ILoad). If the power
dissipation is high, the output voltage may continuously transition on-off-on, due to the
shutdown effect of the thermal limit shutdown circuit.

Thermal Guidelines and Layout Recommendations
Thermal management is a key consideration in the design of any dc-dc converter but is especially
important for an LDO when the power dissipation is high. Use the equation below to approximate the
worst case junction temperature for the application:
TJ = TA + Pd × θJA
(1)
where TJ is the junction temperature (°C), TA is the ambient temperature (°C), Pd is the power dissipation
in the device (Watts), and θJA is the thermal resistance from junction to ambient (°C/W). The maximum
silicon junction temperature should not be allowed to exceed 125°C for reliable operation. The layout
design must use copper traces and plane areas smartly, as thermal sinks, so as to not allow TJ to exceed
the absolute maximum rating under all load, voltage, and temperature conditions for a given application.
The layout should consider carefully the thermal design of the PCB for optimal performance over
temperature. For this EVM, Figure 4 shows that the RGW package footprint employs a square thermal
pad, centered under the part, for conducting heat to the copper spreading layers of the PCB. The thermal
pad is soldered directly to a pad on the PCB containing a 5 × 5 pattern of 10.mil vias for conducting heat
to the bottom side ground plane copper. Approximately 4.0 in2 of 2 ounce copper is used on the bottom
side of the EVM for dissipating heat generated by the LDO.
Table 2 relies on thermal resistance information from the Thermal Information Table of the TPS7A4700
data sheet for comparison with the approximate thermal resistance, θJA, calculated for this EVM layout to
show the variation in junction-ambient thermal resistances for varying copper areas. The High-K thermal
resistance, θJA, is determined using a standard JEDEC high-k (2s2p) board having dimensions of 3 in × 3
in with two 1-ounce internal power and ground planes and one 2-ounce copper bottom plane for
spreading/sinking heat from the IC component.
