AME8830 n Detailed Description Input Capacitor An input capacitance of ≒ 1µF is required between the AME8830 input pin and ground. This capacitor must be located a distance of not more than 1cm from the input pin and returned to a clean analog ground. A ceramic capacitor is recommended. Output Capacitor The AME8830 is designed specifically to work with very small ceramic output capacitors. A 1.0µF ceramic capacitor with ESR between 5mΩ to 500mΩ is suitable in the AME8830 application circuit. It is also recommended that the output capacitor be placed within 1cm from the output pin and returned to a clean ground line. Noise BYPASS Capacitor Connecting a 0.01µF capacitors between the CBYPASS pin and ground significantly reduces noise on the regulator output. This cap is connected directly to a high impedance node in the band gap reference circuit. Any significant loading on this node will cause a change on the regulated output voltage . For this reason, DC leakage current through this pin must be kept as low as possible for best output voltage accuracy. ON/OFF Input Operation 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 1.5µA. The AME8830 is turned off by pulling the EN pin low, and turned on by pulling it high. This pin behaves much like an electronic switch. Fast Turn On-Time The AME8830 output is turned on after VREF voltage reaches its final value(1.205V nomial). The turn on time is determined by the time constant of the bypass capacitor. The smaller the capacitor value, the shorter the turn on time, but less noise gets reduced. 6 Ultra Low Dropout, Fast Turn On 150mA CMOS Regulator AME, Inc.

Due to the difficulty of measuring junction temperature, AME decides to measure +125oC of ambient temperature instead. Heats DUT up to 125oC ambient will result in junction temperature to be higher than +125oC. A marginal failure of Dropout Voltage vs Load Current is negligible. 7 AME, Inc.
