APPLICATION INFORMATION
The AMS1084M series of adjustable and fixed regulators are easy to use and have all the protection features expected in
high performance voltage regulators: short circuit protection and thermal shut-down.
Pin compatible with older three terminal adjustable regulators, these devices offer the advantage of a lower dropout voltage,
more precise reference tolerance and improved reference stability with temperature.
STABILITY
The circuit design used in the AMS1084M series requires the use of an output capacitor as part of the device frequency
compensation.
The addition of 150µF aluminum electrolytic or a 22µF solid tantalum on the output will ensure stability for all operating
conditions.
When the adjustment terminal is bypassed with a capacitor to improve the ripple rejection, the requirement for an output
capacitor increases. The value of 22µF tantalum or 150µF aluminum covers all cases of bypassing the adjustment terminal.
Without bypassing the adjustment terminal smaller capacitors can be used with equally good results.
