Sept. 23, 2013 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today introduced the first current-sharing low-dropout (LDO) linear voltage regulators for harsh environments. The current-sharing feature of the 3-A TPS7H1101-SP and the 0.5-A TPS7H1201-HT allows designers to use two devices in parallel for twice the output current. The devices also offer excellent noise performance, as well as minimize thermal dissipation and increase power efficiency for optimal system reliability. For more information, see
The TPS7H1101-SP LDO is QML Class V-qualified up to 125 degrees C for harsh environments, such as high-reliability medical equipment, satellites and undersea cabling. The TPS7H1201-HT LDO is qualified up to 210 degrees C for high-temperature applications, such as downhole drilling.
Key features and benefits of the TPS7H1101-SP and TPS7H1201-HT LDOs:
Packaging and availability
- Double the current capability: Two TPS7H1101-SP LDOs used in parallel can output up to 6 A, while two TPS7H1201-HT LDOs can output up to 1 A. Sharing the current equally between the matching LDOs reduces stress on the components to meet higher current demands, and time between failures is reduced by half.
- Best-in-class thermal performance: Offers more than 80 percent better thermal performance than similar solutions offered today. The enhanced thermal packaging minimizes thermal temperature for higher reliability.
- Wide input voltage support: The 1.5-V to 7-V input allows voltage support for power rails below 3.3 V.
- Extremely low dropout: Low dropout of 75 mV at 1 A allows for minimal input-to output-voltage conversion for reduced power dissipation.
- Enhanced power supply and noise suppression: Very low output noise of 17 uVrms, coupled with a high power supply rejection ratio of 45 dB at 1 kHz, supports noise-sensitive applications, such as medical equipment and oil and gas exploration equipment.
The TPS7H1101-SP and the TPS7H1201-HT are available now in a 16-pin thermally enhanced ceramic flat pack (CFP). Please contact
