AME8852

Rev. B.01


The AME8852 family of CMOS regulators contain aPMOS pass transistor, voltage reference, error amplifier,over-current protection, thermal shutdown, and PowerGood detection circuitry.

The P-channel pass transistor receives data from theerror amplifier, over-current shutdown, and thermal pro-tection circuits. During normal operation, the error ampli-fier compares the output voltage to a precision reference.Over-current and Thermal shutdown circuits become ac-tive when the junction temperature exceeds 150oC, orthe current exceeds 150mA. During thermal shutdown,the output voltage remains low. Normal operation is re-stored when the junction temperature drops more 20oC.

Capacitor Selection and Regulator Stability

The AME8852 is stable with an output capacitor toground of 1µF or greater. Ceramic capacitors have thelowest ESR, and will offer the best AC performance.Conversely, Aluminum Electrolytic capacitors exhibit thehighest ESR, resulting in the poorest AC response. Un-fortunately, large value ceramic capacitors are compara-tively expensive. One option is to parallel a 0.1µF ce-ramic capacitor with a 10µF Aluminum Electrolytic. Thebenefit is low ESR, high capacitance, and low overall cost.

A second capacitor is recommended between the in-put and ground to stabilize VIN. The input capacitor shouldbe at least 0.1µF to have a beneficial effect.

Enable Pin

The Enable Pin is Active High. When activated pulledlow, the MOS pass transistor shuts off, and all internalcircuits are powered down. In this state, the stand bycurrent is than 1µA. When EN pin float outside, It's pulledhigh.

n Detailed Description Capacitor Selection and Regulator Stability

The maximum output power of the AME8852 is limitedby the maximum power dissipation of the package. Bycalculation the power dissipation of the package as afunction of the input voltage, output voltage and outputcurrent, the maximum input voltage can be obtained. Themaximum power dissipation should not exceed thepackage s maximum power rating.

PMAX = (VIN(MAX)-VOUT) x IOUT

Where: VIN(MAX) = maximum input voltage PMAX = maximum power dissipation of the package
