DESCRIPTION
The UTC M385 is a micropower voltage reference. This device
features good temperature stability and extreme low dynamic
impedance when it is operated over a 20μA to 20mA current. Low
noise and good long-term stability are achieved because the UTC
M385 bandgap reference applies only bipolar transistors and
resistors.
The UTC M385 can be used in almost any reference application
due to the exceptional tolerance of capacitive loading. This voltage
reference can be applied in portable meters, regulators, or
general-purpose analog circuitry with battery life approaching shelf
life. The wide dynamic operating range contributes to its use with
widely varying supplies with excellent regulation. The low power
drain of the UTC M385 is useful for micropower circuitry. On-chip
trimming gives it the tight voltage tolerance. Furthermore, the wide
operating current can replace older references with a tighter
tolerance.
The UTC M385 can be used in such applications, for example,
portable and battery-powered equipment, instrumentation, process
control, energy management, product testing, automotive, precision
audio components, and so on.
FEATURES
* Initial tolerance: 1%
* Operating current range: 10μA~20mA for VR=1.235V
20μA~20mA for VR=2.5V
* Low temperature coefficient
* Low voltage reference
