description
The LP111, LP211, LP311 are low-power versions
of the industry standard LM111, LM211, LM311.
They take advantage of stable, high-value,
ion-implanted resistors to perform the same
function as the LM311 series, with a 30:1
reduction in power consumption but only a 6:1
slowdown in response time. They are well suited
for battery-powered applications and all other
applications where fast response times are not
needed. They operate over a wide range of supply
voltages, from
±
18 V down to a single 3-V supply
with less than 300-
μ
A current drain, but are still
capable of driving a 25-mA load. The LP111,
LP211, and LP311 are quite easy to apply free of
oscillation if ordinary precautions are taken to
minimize stray coupling from the output to either
input or to the trim pins.
The LP111 is characterized for operation over the
full military temperature range of – 55
°
C to 125
°
C.
The LP211 is characterized for operation from
– 25
°
C to 85
°
C, and the LP311 is characterized for
operation from 0
°
C to 70
°
C.
