PRELIMINARY CM3015 Micropower, 300mA Low Dropout CMOS Regulator Features Product Description • The CM3015 is a CMOS linear voltage regulator with low quiescent current, very low dropout voltage and better than 1% fixed output voltage accuracy. The CM3015 ground current is typically 150µA at light loads and only 165µA at 300mA. • • • • • • • • • 300mA output current capability •300mA peak in SOT-23 package •300mA continuous in MSOP package 300mV maximum dropout voltage at full load Excellent line and load regulation Stable with any output capacitor Ultra low noise with optional bypass capacitor Fast power-up with bypass capacitor "Zero" current in Shutdown mode Thermal overload protection Foldback current limiting protection Reverse current protection Load regulation of 0.25% is maintained for peak currents up to 300mA. This is useful for supplying in-rush currents during power-up and transient conditions. The continuous output current is determined by power dissipation, package type and board layout. A dedicated control input (EN, Active High) has been included for power-up sequencing flexibility. When this input is taken low, the regulator is disabled and the supply current will drop to near zero. Applications • • • • The CM3015 also features reverse current protection. This protects the device by blocking the pass transistor’s parasitic diode when the output voltage is forced higher than the input. The device also incorporates overload current limiting and high temperature thermal shutdown protection. Notebook and palmtop computers Cell phones and battery powered devices Consumer and personal electronics PC Card VCC and VPP regulation and switching For low noise performance and increased power supply ripple rejection, a bypass capacitor can be connected to the BYP pin. Connecting this capacitor will not significantly delay the speed of power-up.

If this input is within a few inches of the main supply filter, a capacitor may not be necessary. Otherwise, an input filter capacitor of about 1-10µF will ensure adequate filtering. The negative reference for all voltages. Enable input. When this input is taken low (< 0.4V), the regulator is disabled. In this state, the supply current will drop to near zero. VOUT is the output voltage used to power the load. An output capacitor may not be required for stability, but its use can improve transient response, noise performance and power supply ripple rejection for frequencies over ~100kHz (see note 1).

Adjustable Regulator Application Example Output Compensation Low-dropout regulator topologies use a current-carrying transistor ("pass device") that adds additional gain and phase shift to the design. It is necessary to compensate for these attributes to prevent the design from becoming unstable. The simplest way to do this is to add an output RC filter to roll off the gain. Since all regulators use an output capacitor anyway, the only component needed is a suitable resistance. Fortunately, for the usual range and types of output capacitors, this resistance can be supplied by the ESR of the caps. An attribute of the LDO topology is that the pass device gain generally increases with increasing output current. This may affect output stability: a design that didn't need a capacitor now does, or a design that used a small value now needs a larger one. The CMD advantage is that this component can be selected from any capacitor family without regard to its ESR. If the circuit calls for a tiny, low-ESR capacitor, it will work just fine. For many years, capacitors have been the largest components in regulator circuits, but newer types are shrinking in size rapidly. Unfortunately, their ESRs have shrunk as well, taking them out of the range where they can perform the R function described in existing LDOs. The CM3015 is a new breed of LDO regulator that can work with these tiny low-ESR capacitors and thus permit designs that take a minimum of space. © 2004 California Micro Devices Corp.
