Texas Instruments TPS7A57 | Demoboard TIDA-050061
Scalable, high-current, low-noise parallel low-dropout (LDO) reference design
Overview
| Topology | Other Topology |
| Input voltage | 0.7-6 V |
| Output 1 | 5 V |
| IC revision | A |
Description
The TIDA-050061 parallel low-dropout (LDO) reference design showcases the TPS7A57 low-noise LDO linear regulator in a parallel configuration using ballast resistors, which is capable of sourcing 13 A. A high-performance load-transient circuit is included to assist the user with high-speed load-transient testing. Low inductive current loops also are included to assist with input and output current measurements.
Features
- Load current: 15 A (max)
- Input voltage range: 0.7 V to 6 V
- Selectable output voltages: 0.5 V to 5 V
- VBIAS range: 3 V to 11 V
- Current reference and unity-gain low dropout (LDO)
- TPS7A57EVM-081 EVM supports this reference design
Typical applications
- Ultrasound scanners
- Sensor, imaging, and radar
- Outdoor backhaul units, Active antenna system mMIMO (AAS), Macro remote radio units (RRU)
- Lab and field instrumentation
