Description for the TPS7A21EVM-059
The TPS7A21 evaluation module (EVM) helps design engineers evaluate the operation and performance of the TPS7A21 linear regulator for use in their own circuit application. This EVM configuration contains a single low-noise, small-size, low-dropout (LDO)regulator for a wide range of applications.
The regulator is capable of delivering up to 500 mA to the load with low VIN to VOUT dropout voltage. For stability, use a minimum derated output capacitance of 400 nF (or larger) up to a maximum of 200 µF.
A high-performance load-transient circuit is included to improve the measurement capability of the LDO regulator.
