Note
1. Load and line regulation are specified at constant junction temperature. Change in VO due to heating effects must be taken
into account separately. Pulse testing with low duty is used. 极限参数： | Parameter参数 | Symbol 符号 | Value 数值 | 单位 | | Input Voltage输入电压 | (for VO = -5V, -8V) | VI | -30 | V | | (for VO = -12V to -18V) | -35 | | (for VO = -24V) | -40 | | Operating Junction Temperature Range结温工作范围 | TJ | 0~ +125 | ℃ | | Storage Temperature Range储存温度范围 | TSTG | -65~ +150 | ℃ |
