LM79L12ACM/NOPB

The LM79L12ACM/NOPB is a 3-terminal adjustable positive voltage regulator with a wide range of output current. It belongs to the family of “PMIC – Voltage Regulators – Linear”. With its low cost and high accuracy, it is ideally suited for applications such as power supplies, motor control, instrumentation, and audio amplifiers. It is also commonly used in computer systems and portable equipment.

The LM79L12ACM/NOPB is designed to maintain a steady output voltage of up to 40V, with an accuracy of +/- 0.5V. The output current can range from 1A to 10A, depending on the specified output voltage. It has a low output noise of 65mV maximum, making it an ideal choice for sensitive applications like test equipment, medical equipment and audio amplifiers. This voltage regulator is designed to work with input voltages of up to 35V. It has a very low power-up current of 0.1uA and a low standby current of 0.1uA.

The LM79L12ACM/NOPB is a three terminal device with a pinout arrangement of ground, output and adjustment. The device contains a series pass transistor, which is connected between the input and output for regulation. It has two-phase loop compensation which provides optimum transient performance. The adjustment terminal adjusts the output voltage to a precise level. A built-in temperature compensated shunt regulator, along with short-circuit, over-current and thermal protection prevents the device from being damaged due to faults in the circuit.

The LM79L12ACM/NOPB also has an open-drain enable pin, which is used to enable and disable the regulator. When this pin is asserted low, the regulator is enabled and the output voltage is maintained at the desired level. When the enable pin is asserted high, the output voltage is disabled and the device is in the shutdown mode. The regulator also offers adjustable over-voltage protection, which can be used to detect an output voltage that is too high. When this happens, the output is immediately disabled and protected from further damage.

The LM79L12ACM/NOPB is an ideal device for any application requiring a voltage regulator of high accuracy and wide range of output current. It is available in a small SOT-89 package, and is RoHS compliant, making it ideal for use in green applications. This regulator has been tested for use in a wide variety of automotive, medical, and industrial applications, and is proven to be an efficient regulator for all of them.
