CM2865(A)E5 350mA CMOS LDO HIGH ACCURACY VOUT 1.0% GENERAL DESCRIPTION

FEATURES

The CM2865/A 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 1.0μF 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. ‹ Very Low Dropout Voltage ‹ Low Current Consumption: Typ. 30μA, Max. 35μA ‹ High Accuracy Output Voltage: +/- 1.0% ‹ Guaranteed 350mA Output ‹ Thermal Shutdown ‹ Current Limiting ‹ Reverse battery protection ‹ Compact Package: SOT-89 and SOT-223 ‹ Factory Pre-set Output Voltages ‹ Low Temperature Coefficient

CM2865(A)E5 350mA CMOS LDO HIGH ACCURACY VOUT 1.0% 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.
