1.1 Background
The purpose of the TPS72518EVM is to facilitate evaluation of the TPS725xx
and TPS726xx families of devices. The TPS72518EVM consists of the
SLVP207 PCB, one TPS72518 1.8-V, 1-A linear regulator in a TO–263
package, and supporting passive components. The SLVP207 PCB is
designed to accommodate multiple devices with similar pinouts in different
packages (i.e., TO–220, TO–263, or SOT–223). Specifically, in addition to the
TPS725xx and TPS726xx families, the SLVP207 can be used with the UCx82,
UCx85, TPS755xx, TPS756xx, TPS757xx, TPS758xx, TPS759xx,
TPS786xx, TPS795xx, and TPS796xx families as well as any other device in
the same package with the same pinout.
The TPS725xx and TPS726xx family of parts feature 1-A output current, and
an active high reset (RST) signal that goes high following a fixed delay when
the output voltage reaches 95% of its regulated voltage. Additional features,
as well as detailed specifications of the two families of regulators, can be found
in the TPS725xx data sheet (SLVS341) and the TPS726xx data sheet
(SLVS403).

1.3 Modifications
The TPS72518EVM is designed to allow parts to be easily interchanged.
Although the EVM is designed with a TPS72518 regulator in a TO–263
package, the SLVP207 EVM board also accommodates the SOT–223
packaged version of the device or any other fixed or adjustable voltage option
of TPS725xx or TPS726xx. Passive elements such as the output capacitors
(C4, C5, and C6) and the input capacitor (C3) are easily changed. The board
accommodates the TPS72501 or TPS72601 adjustable versions with
resistors R3 and R4 used as the feedback resistors. Capacitor C2 is used to
reduce the inductance from long input supply leads and may or may not be
necessary, depending on the specific test setup. With JP1 open, the device is
enabled. Shorting JP1 disables the device.
