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.

### 物料型号 - R1161x系列

### 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、用于设置输出电压的电阻、电流限制电路和芯片使能电路组成。这些IC具有低下降电压和芯片使能功能,通过电流限制电路防止过电流破坏。R1161x系列有3种模式:待机模式、快速瞬态模式(FT模式)和低功耗模式(LP模式)。

### 引脚分配 - SOT-23-5:VDD(1),GND(2),CE或CE(3),ECO(4),VOUT(5) - SON-6:VDD(1),NC(2),VOUT(3),ECO(4),GND(5),CE或CE(6) - HSON-6:与SON-6相同

### 参数特性 - 超低供电电流:LP模式下3.5A(Vout<1.6V),FT模式下80A(Vout<1.8V)和60A(Vout≥1.8V) - 待机模式电流:0.1A - 低下降电压:典型值0.31V(负载-300mA,输出电压1.5V类型)和0.23V(负载-300mA,输出电压3.0V类型) - 高纹波抑制:典型值65dB(1kHz,FT模式) - 低温度漂移系数:典型值±100ppm/°C - 优秀的线路调节:典型值0.01%(FT模式) - 高输出电压精度:2.0%(LP模式下3.0%) - 小型封装:SOT-23-5(超小型模具),SON-6,HSON-6 - 输出电压范围:可调至3.3V - 内置折叠保护电路:典型值50mA(短路模式)

### 功能详解 R1161x系列提供内部固定的高准确度输出电压,支持待机模式以实现超小消耗电流。FT模式和LP模式之间保持输出电压不变,但LP模式下消耗电流更少。

### 应用信息 - 精密电压参考 - 相机、VCR、手持通信设备等电器的电源 - 电池供电设备的电源

### 封装信息 - SOT-23-5(SC-74A) - SON-6 - HSON-6
