Description
The VA7070LER is a 10V/5V dual output linear regulator, specifically designed for electronic components in the IC Chips product category. It provides a 10V ±5% output that sources 1A of current, and a 5V ±5% output that sources 250mA of current. Both outputs can be controlled independently using their respective ENABLE pins. When the ENABLE input is high, the associated regulator output turns on. When both ENABLE inputs are low, the IC enters sleep mode, consuming less than 50µA of current. The regulator is equipped with protection against overvoltage, short-circuit, and thermal runaway conditions. It is packaged in a 7 lead TO-220 package with a copper tab, which can be connected to a heat sink if necessary.
Specifications and features
The VA7070LER offers the following specifications and features:
- Two Regulated Outputs:
