EGULATORS
The IL33269 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.
The regulator consists of a 1.0V dropout composite PNP-NPN
pass transistor, current limiting, and thermal shutdown.
