PMIC - Voltage Reference - LM4120AIM5-3.3/NOPB

The LM4120AIM5-3.3/NOPB is an advanced voltage reference specifically designed for high performance voltage regulator modules (VRMs). It is specifically designed to operate with the linear voltage regulator family from Texas Instruments, the TI MDDVR. VRMs provide an efficient, cost effective solution for powering digital ICs and other devices requiring controlled output voltages from 1.5 V to nearly as much as 18 V.The LM4120AIM5-3.3/NOPB provides a low cost, high accuracy voltage reference for powering digital ICs and related components, including memory blocks, CPUs, FPGAs, and ASICs. The standard voltage reference output is 3.3V, with a 5% accuracy over the full operating temperature range of -40°C to +85°C. The device is configured with an enable/disable (EN/DIS) pin to turn the device on or off while maintaining the load current, allowing designers to optimize the load power supply design. Additionally, multiple voltage references can be combined in series in order to achieve higher output voltages.The LM4120AIM5-3.3/NOPB utilizes a two-stage signal conditioning architecture that provides fast transient response, high accuracy, and low noise. In the first stage, a low noise, high accuracy, wide temperature range linear regulator is used to generate the output voltage. To limit output current, the linear regulator is typically combined with a shunting regulator. The second stage uses a precise voltage reference to belt regulate the output voltage and provide precision regulation.The LM4120AIM5-3.3/NOPB requires no external circuitry and has a typical current consumption of only 24 mA. It has a wide operating temperature range from -40°C to +85°C and is designed to meet the automotive, industrial, and medical temperature range requirements. Additionally, the device is compliant with the international safety standards, including IEC 60601, EN 55032 and EN 55024.In summary, the LM4120AIM5-3.3/NOPB is an advanced voltage reference specifically designed for powering high performance voltage regulator modules (VRMs). It has a wide temperature range of operation and offers excellent accuracy and low noise. The device is compliant with international safety standards and requires no external circuitry.
