1.5V Voltage Reference
SE5170
Description
SE5170 is a precision voltage reference that is
designed to work at very low current and low
voltage conditions. The SE5170 can work from a
supply voltage as low as 1.6v, and consumes as low
as 8uA current. Temperature stability is averaging
50ppm/^oC. It is ideal for MP3/MPEG4 applications
where a constant voltage reference is required,
which is independent of the environment
temperature. In addition, SE5170 is designed to be
stable under conditions where Cin and Cout are not
present. However, it is recommended to include Cin
and Cout in the system design as this will increase
the PSRR rating, as shown in the PSRR graph.
Features
¾ Minimum Vin at 1.6V.
¾ Low Ground current as low as 8uA. (Typ.)
¾ Guaranteed 5mA output current over the full
operating temperature range.
¾ Extremely low temperature drift at 50ppm/^oC.
¾ Stable operation without Cin and Cout.
¾ Rugged 5KV ESD withstand capability.
¾ Standard SOT-23-3L package.
Applications
¾ 1.5V Reference for Action 2051, 2085, 2097 MP3
solutions.
¾ 1.5V Temperature Independent Voltage reference.
¾ Other independent voltage reference applications.
