RS7202
250mA Low Quiescent Linear Regulator with Enable
概述
The RS7202 series is a positive voltage regulator with high accuracy output voltage and ultra‐low quiescent current which is
通常2.0μA 。该器件非常适用于手持式通信设备和电池供电应用而
要求低静态电流。
该RS7202由一个带隙基准电压源,误差放大器, P沟道通路晶体管,一个电阻与
除法器,用于设置输出电压,电流限制器,以及温度限制保护电路。高精度输出
voltage is preset at an internally trimmed voltage 1.8V, 2.5V or 3.3V. Other output voltages can be mask‐ optioned from
1.2V to 5.0V with 100mV increment except the RS7202‐13 which has 1.3V output voltage and RS7202‐185 which has 1.85V
输出电压。
The RS7202 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of
1.0μF. The device is available in SOT‐25 package.
