STMicroelectronics A7985A
The A7985A is a step-down switching regulator with a 2.5 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions. The input voltage can range from 4.5 V to 38 V, while the output voltage can be set starting from 0.6 V to VIN. The HSOP8 package with exposed pad allows the reduction of Rth(JA) down to 40 °C/W.| Part No. | A7985A |
