FAQs

What is NCP1117DT33?

The NCP1117DT33 is a low dropout voltage regulator (LDO) designed by ON Semiconductor. It is a 3.3V fixed output voltage regulator capable of delivering up to 1A of output current. The device is suitable for various applications, including voltage regulation in portable devices, battery-powered systems, and industrial equipment.

How Does NCP1117DT33 Work?

The NCP1117DT33 regulates the input voltage to a stable 3.3V output using an internal feedback mechanism. When the input voltage is higher than 3.3V, the regulator adjusts its internal circuitry to maintain a constant output voltage, ensuring a reliable power supply for connected circuits and components.

How Many Pins does NCP1117DT33 have and What are the Functions of the Pinout Configuration?

The NCP1117DT33 is housed in a 4-lead TO-252 package. The pinout configuration includes:

VIN: Input voltage pin.
VOUT: Output voltage pin.
GND: Ground pin.
ADJ: Adjustable pin for voltage trimming (not used in the fixed 3.3V version).

What are the Pros and Cons of NCP1117DT33?

Pros:

High Output Current: Capable of delivering up to 1A of output current.
Low Dropout Voltage: Maintains regulation with a very small voltage drop between input and output.
Thermal Shutdown Protection: Includes built-in thermal shutdown protection for increased reliability.
Small Package: The TO-252 package is space-efficient and suitable for space-constrained designs.
Fixed Voltage Output: The 3.3V fixed output voltage eliminates the need for an external voltage divider or feedback network.

Cons:

Heat Dissipation: May require additional heat sinking in high-power applications to manage thermal dissipation.
Noisier than Some LDO Regulators: May exhibit slightly higher output noise compared to some other LDO regulators.

Are There Any Equivalents/Alternatives to NCP1117DT33 for Recommendation?

Possible equivalents to the NCP1117DT33 include the LM1117 from Texas Instruments and the MIC5205 from Microchip Technology, both of which offer low dropout voltage regulation in various output voltage options.
