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
