DESCRIPTION

The L149 is a general purpose power booster in

Pentawatt ® package consisting of a quasi-com-

plentary darlington output stage with the associat-

ed biasing system an inhibit facility.

The device is particularly suited for use with an op-

erational amplifier inside a closed loop configura-

tion to increase output current.
