Features
Description
●Adjustable or Fixed Output
●Output Current of 1A
●Low Dropout, 1.4V max at 1A Output Current
●Good Noise Rejection
●Output Current Limiting
●Built-in Thermal Shutdown
●Fast Transient Response
The PL5033 series of positive adjustable and fixed
regulators are designed to provide 1A with high
efficiency. All internal circuitry is designed to
operate down to 1.4V input to output differential.
The product is specifically designed to provide well-
regulated supply for low-voltage IC application such
as high-speed bus termination and low current 3.3V
logic supply, and other applications such as VGA cards.
Applications
● High Efficiency Linear Regulators
● Post Regulators for Switching Supplies
● Adjustable Power Supply
