Renesas Electronics ISL6720A
The ISL6720A is a low cost linear regulator for generating a low voltage bias supply from intermediate distributed voltages commonly used in telecom and datacom applications. It produces three separate outputs, an adjustable 0V to 20V output rated at up to 125mA which can be back-biased from an external source such as an auxiliary transformer winding, a 50mA switched regulated output adjustable between 0V and 15V, and a fixed continuous 5V output rated at 25mA. The ISL6720A may be used as a start-up or a continuous low power regulator.| Part No. | ISL6720A |
