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.
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.

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. © ...
