TPS7A3001 and TPS7A4901 Evaluation Board

TPS7A30-49EVM-567

Texas Instruments

The TPS7A30-49EVM-567 is a fully assembled and tested circuit for evaluating the TPS7A3001 and TPS7A4901 low-dropout linear regulators.

Product Description

The Texas Instruments TPS7A30-49EVM-567 EVM helps designers evaluate the operation and performance of the TPS7A3001 and/or the TPS7A4901 LDO regulator for possible use in their circuit applications. This particular EVM configuration is preconfigured to output –15 VDC and +15 VDC 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 1.2 V and 33 V (negative and positive, respectively) as required by only changing a resistor value in accordance with the given equation. The TPS7A3001 can supply up to 200-mA-rated load current and the TPS7A4901 can supply up to 150 mA. 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.

The TPS7A30-49EVM-567 is a fully assembled and tested circuit for evaluating the TPS7A3001 and TPS7A4901 low-dropout linear regulators. The TPS7A30-49EVM-567 includes two independent circuits with outputs of -15V and +15V, respectively. These independent circuits reside on the same module to facilitate evaluation of split rail applications.
