The TPS73701DCQ is a linear low-dropout (LDO) Voltage Regulator uses an NMOS pass element in a voltage-follower configuration. This topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a small 1µF ceramic output capacitor. The NMOS topology also allows very low dropout. This device uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is less than 20nA and ideal for portable applications. This device is protected by thermal shutdown and fold-back current limit. It features reverse current blockage and freedom from output capacitor constraints. These features combined with an enable input makes the device ideal for portable applications.

  • Thermal shutdown and current limit for fault protection
