PJ7900 Series 3-Terminal Negative Output Voltage Regulators T hese voltage regulators are intended as complements to the popular PJ7900 Series devices. These negative Available in fixed output voltage options from -5.0 to - 24 volts, these regulators employ current limiting, thermal shutdown, and safe-area compensation--making them remarkably rugged under most operating conditions. With adequate heatsinking they can deliver output currents in excess of 1 ampere. regulators are available in the same seven-voltage options as the PJ7900 devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative PJ7900 Series.

1. 物料型号： - PJ7900系列为3端负输出电压调节器，提供7种固定输出电压选项，从-5.0V至24V。

2. 器件简介： - PJ7900系列是3端负输出电压调节器，具有电流限制、热关闭和安全区域补偿功能，能在大多数工作条件下表现出色。在适当的散热条件下，可提供超过1安培的输出电流。

3. 引脚分配： - 引脚1：地线； - 引脚2：输入； - 引脚3：输出（散热片表面连接到引脚2）。

4. 参数特性： - 输出电流高达1安培； - 无需外部组件； - 内部热过载保护； - 内部短路电流限制； - 输出晶体管安全区域补偿； - 提供4%的电压公差。

5. 功能详解： - 该系列调节器具有不同的电气特性，如输出电压、线路调节、负载调节、静态电流等，具体参数依据型号不同而有所差异。

6. 应用信息： - 应用时需要在输入和输出电压之间有一个共同的地线。输入电压必须保持比输出电压低20V以上，即使在输入纹波电压的最高点也是如此。

7. 封装信息： - PJ79xxCZ和PJ79xxCI两种型号，分别封装在TO-220和TO-220F中，其中PJ79xxCI的工作温度范围为-20°C至+85°C。
