DETAILED DESCRIPTION
The CM2860/CM2861 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current
protection, thermal shutdown, and short circuit protection.
The P-channel pass transistor receives data from the error amplifier, over-current shutdown, short output protection, and thermal
protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current
and Thermal shutdown circuits become active when the junction temperature exceeds 150℃, or the current exceeds 600mA.
During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops
below 120℃.
The CM2860/CM2861 switches from voltage mode to current mode when the load exceeds the rated output current. This
prevents over-stress. The CM2860/2861 also incorporates current fold-back to reduce power dissipation when the output is
short-circuited. This feature becomes active when the output drops below 0.8V, and reduces the current flow by 65%. Full current
is restored when the voltage exceeds 0.8V.
EXTERNAL CAPACITOR
The CM2860/CM2861 is stable with an output capacitor to ground of 2.2μF or greater. It can keep stable even with higher or poor
ESR capacitors. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should
be larger than 0.1μF to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A “quiet” ground
termination is desirable.
