Specification for packaged product only.
When used in dual supply systems where the regulator load is returned to a negative supply, the output
voltage must be diode clamped to ground.
3:
Full load current (I
FL
) is defined as 1.5A for the MIC2915x, 3A for the MIC2930x, 5A for the MIC2950x,
and 7.5A for the MIC2975x families.
4:
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
5:
Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its
normal value with V
OUT
+ 1V applied to V
IN
.
6:
Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum
of the load current plus the ground pin current.

(nominal) + 1V. For example, use V
IN
= 4.3V for a 3.3V regulator or use 6V for a 5V regulator.
Employ pulse-testing procedures to pin current.

9:
Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipa-
tion is applied, excluding load or line regulation effects. Specifications are for a 200 mA load pulse at V
IN
=
20V (a 4W pulse) for T = 10 ms.
10:
Comparator thresholds are expressed in terms of a voltage differential at the adjust terminal below the
nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage
change, multiply by the error amplifier gain = V
OUT
/V
REF
= (R1 + R2)/R2. For example, at a programmed
output voltage of 5V, the error output is guaranteed to go low when the output drops by 95 mV x
5V/1.240V = 384 mV. Thresholds remain constant as a percent of V
OUT
as V
OUT
is varied, with the drop-
out warning occurring at typically 5% below nominal, 7.7% guaranteed.
