UCC383-5 单输出 LDO、3.0A、固定电压 (5.0V)、反向电流保护、热关断
UCC383-5 描述
The UCC283–3/–5/–ADJ family of positive linear series pass voltage regulators are tailored for low-drop-out applications where low quiescent power is important. Fabricated with a BiCMOS technology ideally suited for low input-to-output differential applications, the UCC283–5 passes 3 A while requiring only 0.45 V of typical input voltage headroom (ensured 0.6-V dropout).
These regulators include reverse voltage sensing that prevents current in the reverse direction. Quiescent current is always less than 650 uA. These devices have been internally compensated in such a way that the need for a minimum output capacitor has been eliminated.
UCC283–3 and UCC283–5 versions are in 3-lead packages and have preset outputs at 3
