KD1084D2T集成电路（IC）的线性+开关稳压器规格书PDF中文资料

KD1084D2T属于集成电路（IC）的线性+开关稳压器。由意法半导体集团制造生产的KD1084D2T稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。

Description

The KD1084 is a LOW DROP Voltage Regulatorable to provide up to 5A of Output Current. Dropout is guaranteed at a maximum of 1.5V at the maximum output current, decreasing at lower loads. The KD1084 is pin to pin compatible with he older 3-terminal adjustable regulators but has better performances in term of drop and output tolerance. A 2.85V output version is suitable for SCSI-2 active termination. Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the KD1084 quiescent current flows into the load, so increase efficiency. Only a 10µF minimum capacitor is need for stability.
