MIC5306中文资料150mA Micropower uCap Baseband LDO数据手册Microchip规格书

描述 Description

The MIC5306 is a micropower, µCap low dropout regulator designed for optimal performance in a small space. It is capable of sourcing 150mA of output current and only draws 16µA of operating current. This high performance LDO offers fast transient response and good PSRR while consuming a minimum of current.Ideal for battery-operated applications, the MIC5306 offers 1% accuracy and extremely low dropout voltage (45mV at 100mA). Equipped with a TTL logic-compatible enable pin, the MIC5306 can be put into a zero off-mode current state, drawing no current when disabled. The MIC5306 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC5306 is available in fixed output voltages in Thin SOT-23-5 packaging.

简介

MIC5306属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC5306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。
