Evaluation Module, Low Dropout Linear Regulator, Low Noise/High PSRR, Programmable Soft Start
The is an evaluation module for TPS7A3001 and TPS7A4901 LDO regulators for possible use in their circuit applications. This particular EVM configuration is preconfigured to output -15V dc and 15V dc for ease of demonstration in certain standard industrial applications, e.g., requiring positive and negative voltages to power an operational amplifier based, signal-conditioning circuitry. Alternatively, each LDO channel can be adjusted individually to any output voltage between 1.2V and 33V negative and positive, respectively as required by only changing a resistor value in accordance with the given equation. The TPS7A3001 can supply up to 200mA rated load current and the TPS7A4901 can supply up to 150mA each using the MSOP 8, Power PAD package. Both circuits have been optimized for ac performance including PSRR and load transient response using capacitors rated over the full voltage range of each regulator.
