600mA CMOS LDO
GENERAL DESCRIPTION
The CM2860/2861 family is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent current (30A typ.), low dropout voltage, and high output low dropout voltage and large output current. A 2.2F or greater can be used as an output capacitor. The SOT-89 and SOT-223 packages are attractive for "Pocket" and "Hand Held" applications. These robust devices are designed to prevent device failure under the worst operation condition with both Thermal Shutdown and Current Fold-back.

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 2.2F 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 0.1F to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A "quiet" ground termination is desirable.
