CM3015 Regulator Family
* For other output voltages, please consult factory.
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 150A at light loads
and only 165A at 300mA.
Load regulation of 0.25% is maintained for peak cur-
rents 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 dis-
sipation, 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.
The CM3015 also features reverse current protection.
This protects the device by blocking the pass transis-
tor'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.
For low noise performance and increased power sup-
ply ripple rejection, a bypass capacitor can be con-
nected to the BYP pin. Connecting this capacitor will
not significantly delay the speed of power-up.
To reduce board cost and layout size the CM3015 was
designed to be stable with or without any output capac-
itor. This includes tiny, low ESR ceramic capacitors.
The CM3015 is available in a low profile, 8-lead MSOP
package and 5 and 6-lead SOT23 packages making it
ideal for space critical applications.

Application Information
Figure 32. Adjustable Regulator Application Example
Output Compensation
Low-dropout regulator topologies use a current-carry-
ing transistor ("pass device") that adds additional gain
and phase shift to the design. It is necessary to com-
pensate 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 reg-
ulators use an output capacitor anyway, the only com-
ponent 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.
For many years, capacitors have been the largest com-
ponents 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 capac-
itors and thus permit designs that take a minimum of
space.
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 advan-
tage 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 the input voltage, Vin minimum will depend on the output current. For
example, if Iout is 100mA, Vin must be at least 4.992V = 1ohm x 100mA =
4.992 + 0.1 = 5.092V.
