Overview

The LM350T/NOPB is a 3A adjustable positive linear voltage regulator. It comes in a TO-220 package and is designed for applications requiring higher output currents than typical general-purpose regulators. It features protection against overcurrent, overtemperature, and short circuits.

Why Choose This Part

Engineers choose the LM350T/NOPB for its robust 3A output current capability and its ability to regulate down to 1.2V. The integrated overcurrent, overtemperature, and short-circuit protection enhance reliability. Its 86 dB ripple rejection (at 120Hz) ensures a clean output voltage.

Applications

Adjustable Power Supplies
Create power supplies with user-selectable output voltages down to 1.2V, suitable for benchtop or embedded use.
Constant Current Regulators
Utilize the regulator's stable output and current limiting features to design constant current sources for LEDs or battery charging.
Battery Chargers
Implement simple and robust battery charging circuits for various battery chemistries, leveraging its current and thermal protection.
