APPLICATIU
Long Battery Life
The LT6650 is a micropower, adjustable reference which
operates from supply voltages ranging from 1.4V to 18V.
The series regulated output may be configured with exter-
nal resistors to any voltage from 400mV to nearly the
supply potential. Under no-load conditions, the LT6650
dissipates only 8
μ
W when operating on a 1.4V supply.
Other operating configurations allow the LT6650 to be
used as a micropower positive or negative adjustable
shunt reference from 1.4V to 18V.

FB (Pin 1):
Resistor Divider Feedback Pin. Connect a
resistor divider from OUT to GND and the center tap to FB.
This pin sets the output potential.
GND (Pin 2):
Ground Connection.
DNC (Pin 3):
Do not connect. Connected internally for post
package trim. This pin must be left unconnected.

IN (Pin 4):
Positive Supply. Bypassing with a 1
μ
F capacitor
is recommended if the output loading changes.
OUT (Pin 5):
Reference Output. The output sources and
sinks current. It is stable with any load capacitor with a
total capacitance of 1
μ
F or more. Higher load capacitance
improves load transient response.

Bypass and Load Capacitor
The LT6650 voltage reference requires a 1
μ
F or greater
output capacitance for proper operation. This capacitance
may be provided by either a single capacitor connected
between OUT and GND or formed by the aggregate of
several capacitors that may be serving other decoupling
functions. Output impedance can be reduced by DC load-
ing of the output by 40
μ
A to 200
μ
A, and/or adding an R
Z
to the output capacitor for a 100
μ
s time constant as shown
in Figure 1 and the Typical Performance Characteristics
graphs.
The LT6650 Voltage reference should have an input by-
pass capacitor of 0.1
μ
F or larger. When the circuit is
