up, and use the TLV705xxxEVM-596.
up, and use the TLV705xxxEVM-596.
2.1
Input / Output Connectors and Jumper Descriptions
J1: VIN
This connector is the input power-supply voltage connector. The positive input lead and ground return
lead from the input power supply should be twisted and kept as short as possible to minimize
electromagnetic interference (EMI) transmission. Additional bulk capacitance should be added between
J1 and J2 if the supply leads are greater than 6 in (15.24 cm) in length. For example, an additional
47-
lead from the input power supply should be twisted and kept as short as possible to minimize
electromagnetic interference (EMI) transmission. Additional bulk capacitance should be added between
J1 and J2 if the supply leads are greater than 6 in (15.24 cm) in length. For example, an additional
47-
μ
F electrolytic capacitor connected from J1 to ground can improve the transient response of the
TLV70528 while eliminating unwanted ringing on the input as a result of long wire connections.
J2: GND
This is the ground-return connection for the input power supply.
J3: VOUT
This is the regulated output voltage connector.
J4: GND
This is the output ground-return connector.
JP1: EN
This jumper is the output enable. To enable the output, connect a jumper to short the VIN pin (pin 1) to
the EN center pin (pin 2). To disable the output, connect a jumper to short the EN pin to GND (pin 3).
the EN center pin (pin 2). To disable the output, connect a jumper to short the EN pin to GND (pin 3).

Soldering Guidelines
Any solder re-work to modify the EVM for the purpose of repair or other application reasons must be
performed using a hot-air system to avoid damaging the integrated circuit (IC).
performed using a hot-air system to avoid damaging the integrated circuit (IC).
2.3
Equipment Setup
Follow these procedures to set up the test equipment properly.
•
Turn off the input power supply after verifying that the output voltage is set to less than 5.5 V. Connect
the positive voltage lead from the input power supply to VIN, at the J1 connector of the EVM. Connect
the ground lead from the input power supply to GND at the J2 connector of the EVM.
the positive voltage lead from the input power supply to VIN, at the J1 connector of the EVM. Connect
the ground lead from the input power supply to GND at the J2 connector of the EVM.
•
Connect a 0-mA to 200-mA load between the output (VOUT) at connector J3 and ground (GND) at
connector J4.
connector J4.
•
Disable the output by jumpering JP1, the EN pin, to the GND pin.

Operation
Follow these guidelines to correctly operate the TLV705xxxEVM-596.
•
Turn on the input power supply. For initial operation, it is recommended that the input power supply,

–
J1, be set to 3.8 V.
•
Enable the output by reconnecting the jumper on JP1 from the EN pin to the VIN pin.
•
Vary the respective loads and VIN voltages as necessary for test purposes.
