Introduction
The TLV705xxxEVM-596 EVM helps design engineers to evaluate the operation and performance of the
TLV705xx family of linear regulators for possible use in their own circuit applications. This particular EVM
configuration contains a single linear regulator with internal thermal and current limit shutdowns, and
enable (disable) circuitry in an extremely small, 0.8-mm

configuration contains a single linear regulator with internal thermal and current limit shutdowns, and
enable (disable) circuitry in an extremely small, 0.8-mm
×
0.8-mm package. The regulator, including
external components, is capable of delivering up to 200 mA to the load depending on the input-output
power dissipation across the device. The TLV705xx does not require an input capacitor and the output
capacitor must only be 1
power dissipation across the device. The TLV705xx does not require an input capacitor and the output
capacitor must only be 1
μ
F (effective minimum) for stability; however, for conservative design practice
that accounts for a wide variety of noisy environments and dynamic line/load conditions, a 1-
μ
F capacitor
is installed at the input and output ports.
