SIP21107集成电路（IC）的线性+开关稳压器规格书PDF中文资料

SIP21107属于集成电路（IC）的线性+开关稳压器。由威世科技半导体制造生产的SIP21107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 SiP21106 BiCMOS 150 mA low noise LDO voltage regulators are the perfect choice for low battery operated low powered applications. An ultra low ground current and low dropout voltage of 135 mV at 150 mA load helps to extend battery life for portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the SiP21106 low output noise.
