n Detailed Description
Capacitor Selection and Regulator Stability
The AME8853 family of CMOS regulators contain a
PMOS pass transistor, voltage reference, error amplifier,
over-current protection thermal shutdown, and Power Good
detection circuitry.
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 150oC, or
the current exceeds 300mA. During thermal shutdown,
the output voltage remains low. Normal operation is restored when the junction temperature drops more 20oC.
The maximum output power of the AME8853 is limited
by the maximum power dissipation of the package. By
calculation the power dissipation of the package as a
function of the input voltage, output voltage and output
current, the maximum input voltage can be obtained. The
maximum power dissipation should not exceed the
package’ s maximum power rating.
PMAX = (VIN(MAX)-VOUT) x IOUT
Where:
VIN(MAX) = maximum input voltage
PMAX = maximum power dissipation of the package
Capacitor Selection and Regulator Stability
The AME8853 is stable with an output capacitor to
ground of 1µF 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 comparatively
expensive. One option is to parallel a 0.1µF ceramic
capacitor with a 10µF Aluminum Electrolytic. The benefit
is low ESR, high capacitance, and low overall cost.
A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should
be at least 0.1µF to have a beneficial effect.
Enable Pin
The Enable Pin is Active High. When activated pulled
low, the MOS pass transistor shuts off, and all internal
circuits are powered down. In this state, the stand by
current is than 1µA. When EN pin float outside, It's pulled
high.
