ICW1235C50E8GQ1

The ICW1235-Q1 is a high-voltage (up to 40V) ultra-low quiescent current LDO regulator fabricated in CMOS technology, capable of delivering up to 200mA of output current while consuming only 1.5μA of quiescent current. The ICW1235-Q1 integrates a bandgap reference, an error amplifier, a current foldback circuit, a phase compensation network, and a pass transistor. The device maintains low quiescent current consumption even in dropout mode, further extending battery life. In shutdown or disabled mode, the device draws less than 100nA of IQ even with an input voltage of 40V, helping to extend battery shelf life. The ICW1235-Q1 is a high-performance LDO regulator designed for automotive applications, with the entire product family certified to the AEC-Q100 standard.
