L7808CV

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The UMW L7808CV is a three-terminal positive linear voltage regulator belonging to the L78xx series. It provides a fixed output voltage of 8 V with a maximum output current capability of 1.5 A. The device accepts an input voltage range up to a maximum of 35 V, requiring a minimum input of 14 V for proper regulation. It features a low quiescent current of 8 mA and operates within a temperature range of 0°C to 125°C. The component utilizes a TO-220-3 through-hole package.
