Texas Instruments TPS7A21EVM-059 Regulator Evaluation Module (EVM)

Texas Instruments TPS7A21EVM-059 Regulator Evaluation Module (EVM) helps design engineers evaluate the operation and performance of the TPS7A21 linear regulator for use in the engineer’s circuit application. The configuration of the Texas Instruments TPS7A21EVM-059 contains a single low-noise, small-size, low-dropout (LDO) regulator for a wide range of applications. The regulator can deliver up to 500mA to the load with low VIN to VOUT dropout voltage. For stability, use a minimum derated output capacitance of 400nF (or larger) up to a maximum of 200µF. A high-performance load-transient circuit is included to improve the measurement capability of the LDO regulator.

Features

  • 6.5µA very low quiescent current (IQ)
  • 2V to 6V input voltage range
  • High power-supply rejection ration (PSRR) (95dB at 1kHz)
  • 7μVRMS low output voltage noise
  • Low dropout (LDO) (171mV (max) at 500mA (3.3V VOUT))
  • Smart enable (EN) pulldown
