R1161x SERIES 3-MODE 300mA LDO REGULATOR NO.EA-106-0511 OUTLINE The R1161x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, and low ON-resistance. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit. These ICs perform with low dropout voltage and a chip enable function. To prevent the destruction by over current, current limit circuit is included. The R1161x Series have 3-mode. One is standby mode with CE or standby control pin. Standby mode realizes ultra small consumption current off mode. Other two modes are realized with ECO pin . Fast Transient Mode (FT mode) and Low Power Mode (LP mode) are alternative with ECO pin . Consumption current is reduced at Low Power Mode compared with Fast Transient Mode. Output voltage is maintained between FT mode and LP mode. The output voltage of these ICs is internally fixed with high accuracy. Since the packages for these ICs are SOT-23-5, SON-6, and HSON-6, high density mounting of the ICs on boards is possible.

器件简介: RICOH R1161x系列是CMOS基础的电压调节IC,具有高输出电压精度、低供电电流和低ON电阻。每个电压调节IC由电压参考单元、错误放大器、设定输出电压的电阻、电流限制电路和芯片使能电路组成。这些IC在低 dropout 电压下工作,并具备芯片使能功能。R1161x系列具有3种模式,包括通过CE或待机控制脚实现待机模式以实现超小消耗电流关闭模式,以及通过ECO脚实现的快速瞬态模式(FT模式)和低功耗模式(LP模式)。在LP模式下相比于FT模式降低了消耗电流,同时保持输出电压不变。

引脚分配: - SOT-23-5封装: - 1号引脚:VDD(输入脚) - 2号引脚:GND(地脚) - 3号引脚:CE或CE(芯片使能脚) - 4号引脚:ECO(模式选择脚) - 5号引脚:VOUT(输出脚) - SON-6和HSON-6封装: - 1号引脚:VDD(输入脚) - 2号引脚:NC(无连接) - 3号引脚:VOUT(输出脚) - 4号引脚:ECO(模式选择脚) - 5号引脚:GND(地脚) - 6号引脚:CE或CE(芯片使能脚)

参数特性: - 超低供电电流:在LP模式下,典型值为3.5A(Vout<1.6V) - 待机模式下消耗电流:0.1A - 低dropout电压:典型值为0.31V(负载-300mA,输出电压为1.5V类型)和0.23V(负载-300mA,输出电压为3.0V类型) - 高纹波抑制:典型值为65dB(1kHz时,FT模式下) - 低温度漂移系数:典型值为±100ppm/°C - 优秀的线路调整率:0.01%(FT模式下) - 高输出电压精度:2.0%(LP模式下为3.0%) - 支持输出电压至3.3V - 内置电流折叠保护电路:短路模式下电流为50mA

功能详解: RICOH R1161x系列LDO稳压器提供高精度的输出电压,并且具有低消耗电流和低ON电阻的特点。它们能够在不同的模式下工作,以适应不同的应用场景,如需要快速瞬态响应或低功耗的应用。
