450 mA High Voltage Ultra Low Iq- Low Dropout Regulator

In automotive always-on, standby systems, designers are constantly seeking ways to reduce the standby power and increase the battery endurance time. The TPS7B67xx-Q1 family is a family of linear regulators that provides 15 uA ultra low quiescent current. At the same time, its output voltage adjustable up to 18 V meets the stringent needs of various applications in automotive.

With ultra-low quiescent current 90% lower than the competition, TI has the family of high current, high voltage linear regulators to help designers with systems requiring ultra-low quiescent current, wide input voltage ranges, thermal shutdown protection, voltage supervision and multiple voltage options -- all increasing battery endurance times in automotive applications.

Product Features & Benefits

  • Ultra-low quiescent current: The TPS7B67xx-Q1 has only 15 uA quiescent current at light loads. This allows ultra-low power consumption while the system is operating under standby mode, increasing vehicle battery life.
  • Wide input voltage range: The TPS7B67xx-Q1 operate normally when the input voltage is between 4 V and 40 V and can survive up to a 45 V load dump voltage. The wide input voltage range allows the device to connect to the battery directly.
  • Thermal shutdown protection: The TPS7B67xx-Q1 offer self-protection against overheating, resulting in better long-term reliability.
  • Voltage Supervision and Enable Functions: The TPS7B67xx-Q1 integrates voltage supervision functions with reset pin and enable function, saving the need for a separate voltage supervisor.
  • Wide ESR range: The TPS7B67xx-Q1 are stable with ESR range between 0.001 Ω and 20 Ω, resulting in output cap selection flexibility and cost reduction.
  • Multiple voltage options: The TPS7B67xx-Q1 are available in fixed 5 V, 3.3 V and adjustable version (1.5 V to 18 V).
