The LMV431BCM5/NOPB is a programmable shunt regulator that performs the same functions of other unity-gain voltage references, but allows the output voltage to be adjusted over a wide range.

It is designed to provide a stable output voltage despite fluctuations in the input power. The device can be used with standard linear regulators, PLLs, clocks, RF front ends, amplifiers, analog-to-digital converters and other circuits with high accuracy.

The LMV431BCM5/NOPB is a low-cost, low-power, 8-pin dual-in-line (DIL) voltage reference suitable for any general-purpose low-voltage application. It has an 8-bit resolution that enables wide temperature compensation and wide range of voltage reference levels that make it suitable for many different applications.

The LMV431BCM5/NOPB includes a regulated output voltage and a three-state output drive. The three-state output drive allows the user to select an output voltage between 0 V and the output voltage. This makes the output flexible and can be used to adjust the output voltage as needed.

The LMV431BCM5/NOPB includes an on-chip voltage reference with a high accuracy of ±0.1 %. By changing the value of the voltage reference, the user can set the output voltage of the LMV431BCM5/NOPB. The use of the on-chip reference ensures a stable output voltage and the output is insensitive to changes in the input power.

The LMV431BCM5/NOPB can operate in either a single-ended or differential mode. In single-ended mode, the reference voltage is applied to the input of the reference amplifier while the output is connected to the output of the reference amplifier. In differential mode, the reference voltage is applied to the non-inverting input of the reference amplifier and the output is connected to the inverting input of the reference amplifier.

The LMV431BCM5/NOPB features protection diodes on the output of the device to protect against reverse voltage and short-circuits. The protection diodes ensure the device will not be damaged due to any short circuit or reversed voltage conditions. The device also has an on-chip thermally-enhanced trim-capable voltage reference unit. This allows the user to fine-tune the output voltage by adjusting the trimming capacitor, either to increase or decrease the voltage.

The LMV431BCM5/NOPB is a popular choice for PMIC – Voltage Reference applications and is suitable for a wide range of applications. The accuracy, low power consumption, on-chip trimming, protection diodes and wide temperature range of operation make it a suitable choice for many low-voltage applications, from timers and voltage regulators to RF front-end amplifiers.
