Datasheet Summary
Dual Channel LDO Regulator With Enable Function
Description
The EC49222 series are highly accurate, dual, low noise, CMOS LDO voltage regulators with enable function. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption.
The EC49222 series have the soft start function to suppress the inrush current. The current limiters' fold back circuit (it happens when over 350mA per channel) also operates as a short protection for the output current limiter. The output voltage for each regulator is set independently by metal trimming. It's also available to offer the honors other types of VOUT between +1.2V~+3.9V...
