8 / 12 page AME 8 300mA CMOS LDO with RESET Function AME1300 Rev.C.02 When actively pulled low, the PMOS pass transistor shuts off, and all internal circuits are powered down. In this state, the quiescent current is less than 10 µA. This pin behaves much like an electronic switch. RESETB Output The RESETB output is driven active low within 40 µsec of V DET falling through the reset threshold.RESETB is maintained active for a minimum of 140msec after V DET rises above the reset threshold. The AME1300 has an active-low RESETB output. The output of the AME1300 is guaranteed vaild down to V DET = 1V and is optimized to reject fast transient glitches on the V DET line. The AME1300 is stable with an output capacitor to ground of 2.2 µF or greater. Ceramic capacitors have the lowest ESR, and will offer the best AC performance. Con- versely, Aluminum Electrolytic capacitors exhibit the high- est ESR, resulting in the poorest AC response. Unfortu- nately, large value ceramic capacitors are comparatively expensive. One option is to parallel a 0.1 µF ceramic ca- pacitor with a 10 µF Aluminum Electrolytic. The benefit 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 should be at least 0.1 µF to have a beneficial effect. A third capacitor can be connected between the BY- PASS pin and GND. This capacitor can be a low cost Polyester Film variety between the value of 0.001~0.01 µF. A larger capacitor improves the AC ripple rejection,but also makes the output come slowly. This “Soft” turn-on is desirable in some applications to limit turn-on surges. 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. n External Capacitors n Enable |
