RP102中文资料低噪声300mA LDO稳压器数据手册Nisshinbo规格书

描述 Description

The RP102 Series are CMOS-based LDO regulators featuring 300mA output. The RP102 features supply current as low as 50µA, which is far lower than existing lines. Due to a built-in 0.4Ω (at VSET=2.8V) on-resistor, RP102 can provide a low dropout voltage. RP102 also features excellent line transient response, ripple rejection at 80dB, and low noise. The output voltage accuracy is as high as ± 0.8% and the temperature drift coefficient of output voltage is low at ± 20ppm/°C.

简介

RP102属于集成电路（IC）的稳压器-线性。由制造生产的RP102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。
