MC33269/D
MC33269, NCV33269
800 mA, Adjustable Output,
Low Dropout Voltage
Regulator
The MC33269/NCV33269 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 1.0 V dropout composite PNPNPN pass
transistor, current limiting, and thermal shutdown.
