Texas Instruments TPS7A43 | Demoboard TPS7A43EVM-047
TPS7A43 50-mA, 85-V, ultra-low IQ, dual LDO voltage regulator with power good evaluation module
Overview
| Topology | Other Topology |
| Input voltage | 4-85 V |
| Output 1 | 14.5 V / 0.05 A |
| IC revision | B |
Description
The TPS7A43EVM-047 evaluation module (EVM) is a platform for evaluating the operation and performance of the TPS7A43 linear regulator. This EVM configuration contains a single 50-mA, high-voltage, low-quiescent-current (IQ), dual-output, low-dropout (LDO) voltage regulator for general applications. The regulator is capable of delivering up to 50 mA split between the two outputs and has a wide input voltage (VIN) range of up to 85 V.For stability of the TPS7A43, use a 1-µF (or larger) output capacitor (COUT) and at least 3 × COUT for the middle output
Features
- Ultra-low IQ: 9 µA
- Wide input range: 4 V to 85 V
- Dual output
- Precision enable
Typical applications
- DC motors and fans, Cordless power tools, Programmable logic controllers (PLCs)
- Field transmitter and process sensors, Smoke and heat detectors
- EV charging infrastructure
- Battery packs
