Delivers up to 150mA output current Very low dropout (150mV at 150mA) Low quiescent operating current (110µA) Stable with low-ESR ceramic capacitors “Zero” disable mode current consumption Thermal overload protection Foldback overload current protection -40°C to +85°C temperature operation Available in a 5-pin SOT23 and 5-bump Chip Scale Packages (CSP) Lead-free versions available Product Description The CM3018 is a very low dropout, low noise regulator that delivers up to 150mA of load current at a fixed output voltage. A dedicated control input (EN, Active High) provides power-up sequencing flexibility. When this input is taken low, the regulator is disabled. In this state, the supply current will drop to near zero. An internal discharge MOSFET resistance (300Ω) will force the output to ground whenever the device is disabled. An optional bypass pin is provided for further improvement of noise performance and to maximize the power supply ripple rejection. The CM3018 is fully protected, offering both overload current limiting and high temperature thermal shutdown. The CM3018 is available in a tiny 5 lead SOT-23 package or a 5-bump CSP and is ideal for space critical applications. The CS...
