1 Introduction
The Texas Instruments TPS7A14EVM-058 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS7A14 LDO voltage regulator. As shown in
, the TPS7A14EVM-058 contains
one TPS7A14 LDO voltage regulator in the DSBGA package. An optional load transient circuit is also included
to assist the user with high-speed load transient testing. An input current loop is included that allows fast
measurements of the input current.

2.1 LDO Input/Output Connector Descriptions
2.1.1 VIN and GND
VIN and GND are the connection terminals for the input supply. The VIN terminal is the positive connection, and
the GND terminal is the negative (that is, ground) connection.
2.1.2 BIAS and GND
BIAS and GND are the connection terminals for the bias supply. The BIAS terminal is the positive connection,
and the GND terminal is the negative (that is, ground) connection.
2.1.3 VOUT and GND
VOUT and GND are the connection terminals for the output load. The VOUT terminal is the positive connection,
and the GND terminal is the negative (that is, ground) connection.
2.1.4 EN
EN is a 3-pin header used to enable or disable the TPS7A14.
The center pin of the 3-pin header is tied to the TPS7A14 EN input. When the 2-pin shunt is placed across the
top two pins of the header, VIN is shorted to EN, and the TPS7A14 is enabled. When the 2-pin shunt is placed
across the bottom two pins of the header, GND is shorted to EN, and the TPS7A14 is disabled.
When driving the EN terminal with an off-board supply or signal generator, the applied voltage must be kept
between 0 V and 5.5 V.
2.2 Optional Load Transient Input/Output Connector Descriptions
2.2.1 VDD and GND
VDD and GND are the connection terminals for the input supply of the load transient circuit. The VDD terminal is
the positive connection, and the GND terminal is the negative (that is, ground) connection.
2.2.2 J13
J13 is an optional connection for the user to make measurements or apply loads to the output of the LDO.
2.2.3 J15
J15 is an optional connection to insert a damping circuit across the load transient MOSFET drain to source
voltage.
2.2.4 J16
J16 is an optional connection to insert capacitance or additional load across the drain to source of the load
transient MOSFET.
