description
The
LT1009
reference
circuit
is
a
precision-trimmed 2.5-V shunt regulator featuring
low dynamic impedance and a wide operating
current range. The maximum initial tolerance is
鹵
5 mV in the LP package and
鹵
10 mV in the
D package. The reference tolerance is achieved
by on-chip trimming, which minimizes the initial
voltage tolerance and the temperature
coefficient
偽
vz
.
Although the LT1009 needs no adjustments, a
third terminal (ADJ ) allows the reference voltage
to be adjusted
鹵
5% to eliminate system errors. In
many applications, the LT1009 can be used as a
terminal-for-terminal replacement for the
LM136-2.5, which eliminates the external trim
network.

The LT1009 uses include 5-V system references, 8-bit ADC and DAC references, and power-supply monitors.
The device also can be used in applications such as digital voltmeters and current-loop measurement and
control systems.
The LT1009C is characterized for operation from 0擄C to 70擄C. The LT1009I is characterized for operation from
鈥?40擄C to 85擄C.
