RP101数据手册集成电路（IC）的稳压器-线性规格书PDF

描述 Description

The RP101 Series are CMOS-based LDO regulators featuring 300mA output. RP101 has the supply current as low as 18µA, which is far lower than current products. Due to a built-in transistor with low on-resistance of 0.87Ω (at VSET=2.8V) , RP101 provides a low dropout voltage. RP101 also has an excellent line transient response, 75dB ripple rejection, and low noise. The output voltage accuracy has been improved to ± 0.6% and the temparature drift coefficient of the output voltage is as low as ± 30ppm/°C.

简介

RP101属于集成电路（IC）的稳压器-线性。由制造生产的RP101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。
