PRELIMINARY  
CM3018  
Micropower, 150mA Low Noise CMOS Regulator  
with Fast Response  
Features  
Product Description  
Available with 1.5V, 1.8V, 2.5V, 2.6V, 2.8V, 2.85V,  
2.9V, 3.0V, 3.1V or 3.3V outputs  
Fast (60µs) V response when enabled  
The CM3018 is a very low dropout, low noise regulator  
that delivers up to 150mA of load current at a fixed out-  
put voltage.  
OUT  
Ultra low noise (35µV rms typ.)  
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 dis-  
charge MOSFET resistance (300) will force the out-  
put to ground whenever the device is disabled.  
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)  
An optional bypass pin is provided for further improve-  
ment 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 shut-  
down.  
Lead-free versions available  
Applications  
Wireless handsets, PDAs, MP3 players, digital  
cameras  
PCs and notebooks  
Graphics cards, set-top boxes  
Compact Flash memory cards  
Battery-powered devices  
PC cards  
The CM3018 is available in a tiny 5 lead SOT-23 pack-  
age or a 5-bump CSP and is ideal for space critical  
applications. The CSP version of the CM3018 incorpo-  
rates OptiGuardTM technology to provide increased reli-  
ability at assembly.  
All versions of the CM3018 are now available with  
optional lead-free finishing.
