10 / 17 page  AME, Inc. 10 1.5A CMOS LDO AME8815 n n n n n Detailed Description The AME8815 family of CMOS regulators contain a PMOS pass transistor, voltage reference, error ampli- fier, over-current protection, and thermal shutdown. The P-channel pass transistor receives data from the error amplifier, over-current shutdown, and thermal pro- tection circuits. During normal operation, the error am- plifier compares the output voltage to a precision refer- ence. Over-current and Thermal shutdown circuits be- come active when the junction temperature exceeds 150oC, or the current exceeds 2.2A. During thermal shut- down, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120oC. The AME8815 behaves like a current source when the load reaches 2.2A. However, if the load impedance drops below 0.3 ohms, the current drops back to 600mA to prevent excessive power dissipation. Normal op- eration is restored when the load resistance exceeds 0.75 ohms. n n n n n External Capacitors The AME8815 is stable with an output capacitor to ground of 4.7 µF or greater. Ceramic capacitors have the lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC response. Unfortunately, large value ceramic capacitors are com- paratively expensive. One option is to parallel a 0.1 µF ceramic capacitor with a 10 µF Aluminum Electrolytic. The benefit is low ESR, high capacitance, and low over- all cost. A second capacitor is recommended between the input and ground to stabilize Vin. The input capacitor should be at least 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. This can be achieved with a "Star" connection. |
