desired. (The LTC1263 does not require a 0.1
μ
F capacitor
between V
CC
and V
OUT
for stability.)
Besides using it to program flash memories, the LTC1263
can also provide multiple supply voltages with the help of
W
U
two diodes and two capacitors. Output voltages of 19V and
–7V can easily be obtained. In other words, the LTC1263
can power dual supply (
±
5V) and single supply (15V) op
amps.
