AP7332-3333W6-7集成电路（IC）的线性+开关稳压器规格书PDF中文资料

AP7332-3333W6-7属于集成电路（IC）的线性+开关稳压器。由美台半导体制造生产的AP7332-3333W6-7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。

描述 Description

The AP7332 is 300mA, dual fixed output voltage, low dropout linear regulator. The AP7332 includes the pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry which protect the IC from damage in fault conditions. The AP7332 has two enable pins (EN1 and EN2) to

independently turn the respective channel on when a logic high level is applied.
