Programming The output Voltage
The TS2951/A output voltage is programmable for any
value from it reference voltage of 1.235V and it maximum
rating of 30V. For example for 5 volt needs to
pin-strapped and using the internal voltage divider by
tying pin 1 to 2 and pin 7 to pin 6. Refer to Figure 2, there
are two external resistor required for this programming.
Refer to the below equation for the programming the
output voltage:
Volt=Vref x (1+R1\R2)+I
FB
* R1
The Vref is 1.235V and I
FB
is the feedback bias current,
nominally -20nA. The minimum recommended load
current of 1uA forces an upper limit of 1.2M
on value of
R2, If no load presented the I
FB
produces error of typically
2% in Vout which maybe eliminated at room temperature
by trimming R1. To improve the accuracy chooses the
value of R2=100K and this reduces the error by 0.17%
and increases the resistor program current by 12uA. The
TS2951/A typically draw 60uA at no load with pin 2
open-circuit, and this value does not look much.
