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.

* AME specifies full temperature range
as -40oC to +125oC of junction temperature. 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.
