TPS7A3701DRVT

The Texas Instruments TPS7A3701DRVT is an adjustable positive output linear voltage regulator designed for high-performance applications. It operates with an input voltage range of 2.2 V to 5.5 V and provides an output voltage adjustable from 1.2 V to 5.5 V, with a maximum output current of 1 A.

Key electrical specifications include a typical dropout voltage of 130 mV at 1 A and a maximum of 200 mV at 1 A. The device boasts high accuracy, with 1% overall accuracy over line, load, and temperature, and a nominal accuracy of 0.23%. It features low noise (32 µVrms) and good PSRR performance, ranging from 58 dB to 37 dB across 100 Hz to 10 kHz. The quiescent current is typically 0.4 mA, dropping to less than 20 nA in shutdown mode.

Protection features include overcurrent, overtemperature, reverse polarity, and under-voltage lockout (UVLO). The TPS7A3701DRVT is stable with a 1-µF or larger ceramic output capacitor and offers excellent load transient response. It is available in a 6-WSON (2x2 mm) package, suitable for surface mounting.

The operating temperature range is -40°C to 125°C, with a thermal resistance of 67 °C/W. The regulator includes an enable pin for control and features NMOS topology for low reverse leakage current.
