EUP7907-28VIR1 数据手册
EUP7907 600mA High PSRR Low Dropout Linear Regulator DESCRIPTION The EUP7907 is a high current, low dropout linear regulator with fast transient response and high PSRR. It offers high output accuracy, extremely low dropout voltage, low quiescent current and fast start-up time. The EUP7907 is designed to work with low-ESR ceramic capacitor, reducing the amount of the PCB area necessary for power applications. Only a 2.2uF ceramic capacitor can make the device stable over the whole load range. The EUP7907 monitors the input voltage for power on reset to ensure the regulator is disabled when the input voltage is not high enough for normal operation. When EUP7907 detects fault signal, such as over-temperature, it will turn off the pass transistor and discharge VOUT to GND from the internal resistor. EUP7907 can be operated in two modes, operated in fixed mode when the FB pin connected to ground, its output is a pre-set value:0.8V~3.6V. There is no external component needed to decide the output voltage. Operated in adjustable mode when the FB pin connected to two external resistors divider, its output can be adjusted from 0.8V to 5V. Other key features include over-current protection, thermal shutdown. The device can be available in the TDFN-8 package or SOT23-5 package. FEATURES 2.5V to 5.5V Input Voltage Range 300mV@600mA Dropout Voltage Excellent Transient Response Stable with 2.2uF Ceramic Output Capacitor 70dB PSRR at 1kHz Low 120µA Quiescent Current Low Shutdown Current:

1. 物料型号: - EUP7907

2. 器件简介: - EUP7907是一款高输出电流、低 dropout 线性稳压器,具有快速瞬态响应和高电源抑制比(PSRR)。它提供高输出精度、极低的dropout电压、低静态电流和快速启动时间。

3. 引脚分配: - SOT23-5和TDFN-8两种封装类型的引脚配置如下: - VIN(输入电压) - GND(信号地) - EN(使能引脚) - FB(反馈引脚) - VOUT(输出电压) - NC(无连接引脚)

4. 参数特性: - 输入电压范围:2.5V至5.5V - Dropout电压:@600mA时为300mV - 2.2uF陶瓷输出电容器即可稳定整个负载范围 - PSRR:在1kHz时为70dB - 静态电流:低至120uA - 关闭时电流:<1uA - 初始准确度:2%

5. 功能详解: - EUP7907由带隙参考电压、误差放大器、P沟道MOSFET通道晶体管、内部电阻分压器和一些额外的保护电路组成。 - 如果反馈电压低于参考电压,通道晶体管门被拉低以增加其导电性,从而增加输出电压。 - 如果反馈电压高于参考电压,通道晶体管允许较少电流流向输出。 - 反馈点是连接到VOUT引脚的内部或外部电阻分压器的输出。

6. 应用信息: - 适用于移动电话、蓝牙便携式收音机和附件、电池供电设备、笔记本电脑等。 - 需要选择合适的电阻和外部电容器,以优化精度和稳定性。 - 输入电容器需2.2uF,无ESR要求,但需考虑公差和温度系数。 - 输出电容器设计用于与非常小的陶瓷电容器一起工作,容量在2.2uF至10uF之间,ESR范围在5mΩ至500mΩ。

7. 封装信息: - EUP7907提供TDFN-8和SOT23-5两种封装选项。 - 封装尺寸和热性能参数根据不同封装有所不同,具体尺寸和热阻抗参数在PDF中有详细说明。
