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:
- 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.
Packaging and availability
The TPS7H1101-SP and the TPS7H1201-HT are available now in a 16-pin thermally enhanced ceramic flat pack.
Tools and support
The TPS7H1101-SPEVM and the TPS7H1201-HTEVM evaluation modules are available to test performance at different input and output voltages and various load conditions.
The TPS7H1101-SP and the TPS7H1201-HT join TI’s portfolio of products for harsh environments. To supply power to the LDOs, TI offers the6-A TPS50601-SP and the 3-A TPS50301-HT monolithic point of load converters, both supporting input voltages from 1.6 V to 6.3 V.
A SPICE model is also available for designing, testing and troubleshooting a broad variety of basic and advanced circuits, including complex architectures, without any node or number of device limitations.
