n DESCRIPTION
The LM385-2.5 is a micropower 2-terminal band-
gap voltage reference, which can operate in a
20µA to 20mA current range, they feature excep-
tionally low dynamic impedance and good tem-
perature stability. On-chip trimming is used to
achieve tight voltage tolerance. Since the LM385-
2.5 bandgap reference uses only transistors and
resistors, low noise and good long-term stability
result.
Careful design of the LM385-2.5 has made the de-
vice exceptionally tolerant of capacitive loading,
making it easy to use in almost any reference ap-
plication. The wide dynamic operating range al-
lows for its use with widely varying supplies with
excellent regulation.
The extremely low power drain of the LM385-2.5
makes it useful for micropower circuitry. This volt-
age reference can be used to make portable me-
ters, regulators, or general purpose analog circui-
try with battery life approaching shelf life. Further,
the wide operating current allows it to replace
older references with a tighter tolerance.
