DALLAS (August 19, 2014) – Broadening its large portfolio of low drop-out regulators (LDOs), Texas Instruments (TI) (NASDAQ: TXN) today introduced 17 new AEC-Q100-qualified, high-voltage LDOs for automotive and industrial applications. The new ultra-low quiescent current LDOs, including the TPS7A16xx-Q1 with 60-V input, TPS7A66xx-Q1 and TPS7B67xx families, and the TPS7B4250-Q1 LDO, support many applications that connect directly to a car or truck battery, such as cluster, power steering and infotainment systems, door modules and lighting controls. For more information, to order samples or purchase evaluation modules for the new ultra-low quiescent current, high-voltage LDOs, visit www.ti.com/autoldo-pr.

 

Key features and benefits of the new LDOs:

  • Ultra-low quiescent current extends battery life: The new LDOs achieve quiescent current as low as 10 uA in standby mode, resulting in lower power consumption and increased battery life.
  • Internal equivalent series resistance (ESR) compensation can help optimize system cost and stability: Designers have the flexibility to choose from a wide range of output capacitors, including ceramic, to reduce system cost and increase stability.
  • High input voltage allows automotive subsystems to connect directly to the car battery: The LDOs support input voltages of up to 40 V for normal operation and up to 45 V to support transient spikes in automotive designs. Additionally the TPS7A1601-Q1 can support up to 60-V normal operation for trucks and heavy-duty equipment.
  • Tracking function allows for more accurate data from the off-board sensors: Tracking provides close to zero tolerance between on-board and off-board power supplies. Tracking helps customers get more accurate data from the off-board sensors.
  • Integrated window watchdog supports functional safety: The integrated window watchdog enables customers to meet the functional safety requirements on the system level.

 

Tools and support

Designers can test drive the new AEC-Q100-qualified LDOs using several featured evaluation modules and SPICE simulation models that make it easy to evaluate and design.
