DETAILED DESCRIPTION

The CM2830/CM2830A 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 300mA.

During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops

below 120℃.

The CM2830/CM2830A switches from voltage mode to current mode when the load exceeds the rated output current. This

prevents over-stress. The CM2830 also incorporates current fold-back to reduce power dissipation when the output is

short-circuited. This feature becomes active when the output drops below 1.05V, and reduces the current flow by 65%. Full

current is restored when the voltage exceeds 1.05V.

EXTERNAL CAPACITOR

^{The CM2830/2830A is stable with an output capacitor to ground of 2.2}µF 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 0.1}µF to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A “quiet” ground

termination is desirable.
