Advance Information
Low Dropout Positive
Fixed and Adjustable
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.
The regulator consists of a 1.0 V dropout composite PNP±NPN pass transistor, current limiting, and thermal shutdown.
•3.3 V, 5.0 V, 12 V and Adjustable Versions
•Space Saving DPAK, SOP±8 and SOT±223 Power Packages
•1.0 V Dropout
•Output Current in Excess of 800 mA
•Thermal Protection
•Short Circuit Protection
•Output Trimmed to 1.0% Tolerance
•No Minimum Load Requirement for Fixed Voltage Output Devices
