ISL80121-5开发板套件编程器的评估板-线性稳压器规格书PDF中文资料

The ISL80121-5 is a low dropout voltage, single output LDO with programmable current limiting.

This LDO operates from input voltages of 2.2V to 6V. The ISL80121-5 has a nominal output

voltage of 5V. Other custom voltage options are available upon request.

A sub-micron BiCMOS process is utilized for this product family to deliver the best in class analogperformance and overall value. The programmable current limiting improves system reliability of end applications. An external capacitor on the soft-start pin provides an adjustable soft-starting ramp. The ENABLE feature allows the part to be placed into a low quiescent current

shutdown mode.
