AS1362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

General Description

The AS1361/AS1362 are ultra-low-noise, low-dropout linear regulators specifically designed to deliver up to 150/300mA continuous output current, and can achieve a low 140mV dropout for 300mA load current. The LDOs are designed and optimized to work with low-cost, small capacitance ceramic capacitors.
