CM2860/CM2861
600mA CMOS LDO
GENERAL DESCRIPTION
The CM2860/2861 family is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent current (30μA typ.), low dropout voltage, and high output voltage accuracy. Built-in low on-resistance transistor provides low dropout voltage and large output current. A 2.2μF 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.
FEATURES
Very Low Dropout Voltage Low Current Consumption: Typ. 30μA, Max. 35μA High Accuracy Output Voltage: +/- 1.5% Guaranteed 600mA Output Thermal Shutdown Current Limiting Compact Package: SOT-89 and SOT-223 Factory Pre-set Output Voltages Short Circuit Current Fold-Back Low Temperature Coefficient
APPLICATIONS
