LOW DROPOUT
THREE–TERMINAL
VOLTAGE REGULATORS
The MC33269 series are low dropout, medium current, fixed and
adjustable, positive voltage regulators specifically designed for use in low
input voltage applications. These devices offer the circuit designer an
economical solution for precision voltage regulation, while keeping power
losses to a minimum.
D SUFFIX
PLASTIC PACKAGE
The regulator consists of a 1.0 V dropout composite PNP–NPN pass
transistor, current limiting, and thermal shutdown.
