DETAILED DESCRIPTION
The CM2865 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error amplifier, over-current
protection and thermal shutdown.
The P-channel pass transistor receives data from the error amplifier, over-current shutdown, 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 175℃, or the current exceeds 350mA. During thermal
shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120℃.
EXTERNAL CAPACITOR
The CM2865 is stable with an output capacitor to ground of 1.0μF 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.
