Working Principle

The LM4130DIM5-2.5/NOPB operates on an internal bandgap reference (BGR) that provides a highly stable voltage output over a wide temperature range. When a voltage is applied to the device’s reference input, it adjusts the output voltage to match the reference voltage, thus providing a precise output voltage. The output voltage is then buffered by an internal amplifier, providing a low output impedance and high current drive capabilities. The LM4130DIM5-2.5/NOPB also features an internal low-pass filter that reduces output noise and makes the output signal more stable.

The device is very tolerant to input voltage variations and can operate with a wide range of input voltage. It has an operating temperature range of -40°C to +85°C, which makes it well suited for use in industrial and harsh environments. The device is also available in a metal can package and can be operated in lead-free reflow solder processes.
