SSP7785

Short Description:

The SSP7785 is a high−performance linear regulator, offering a very wide operating input voltage range of up to 450 VDC, with an output current of up to 10 mA. Ideal for high input voltage applications. The SSP7785 family offers ±5% initial accuracy, extremely high−power supply rejection ratio and ultra−low quiescent current. The SSP7785 is optimized for high−voltage line and load transients, making this part ideal for harsh environment applications. The SSP7785 is offered in fixed output voltage options 2.7V,3.3V and 5.0V.
