Figure 41. Boosted Output Reference
Higher current drive capability can be obtained, without
sacrificing accuracy, by using the circuit in Figure 41. The
operational amplifier regulates the MOSFET turn-on, forcing
V
O
to equal the V
REF
. Current is then drawn from V
IN
, allowing
increased current drive capability. The circuit allows a 50 mA
load; if higher current drive is required, use a larger MOSFET.
For fast transient response, add a buffer at V
O
to aid with
capacitive loading.
