Review NATIONAL SEMICONDUCTOR 100 Pcs Lot Terminal Adjustable Current Sources Chip Ic

The LM334M is a highly versatile adjustable voltage regulator integrated circuit (IC) produced by National Semiconductor. This SOT-8 packaged chip, specifically marked as PCS (Plastic Common Anode), is widely used to generate precise and stable output voltages, making it an essential component for various electronic circuits and systems.

The LM334M operates on a constant voltage, constant current (CVCC) principle. It is designed to accept a wide input voltage range of 6.5 Volts to 36 Volts, allowing it to operate in various battery-powered or AC-powered applications. This adjustable voltage regulator features a simple and accurate voltage setting, with a precision that can be adjusted from 1.2 Volts to 3.3 Volts.

The LM334M is equipped with several internal protection features, ensuring optimal performance and reliable operation. It includes a thermal shutdown mechanism that activates when the junction temperature goes above 125 C, protecting the chip from thermal runaway. Additionally, the output short-circuit protection automatically engages when the output voltage is shorted, preventing potential damage to the circuit.

The adjustment voltage of the LM334M is done using a single external potentiometer. This external resistance sets the output voltage through a voltage divider circuit connected to the input pin 7. Once adjusted, the circuit begins regulating the output voltage and maintains it despite changes in input voltage or output load resistances.

The LM334M also features a low dropout voltage (typically 2.5 Volts at minimal load), enabling the regulator to maintain a consistent output voltage even when the input voltage is close to the output voltage. It also boasts a low noise specification of only 80mV max without capacitors at full load.

This adjustable voltage regulator is suitable for numerous applications such as battery chargers, hand-held devices, low power microcontrollers, LED driver circuits, and test equipment. With its robust features, high precision, and ease of use, the LM334M is an indispensable element in many electronic designs.
