Product details

Fixed 3.3 V series reference in a SOT-23-5

The Texas Instruments LM4120IM5X-3.3/NOPB is a series voltage reference with a fixed 3.3 V output and ±0.5% tolerance. It operates from 2 V to 12 V input and sources up to 5 mA.

What the ratings mean for the BOM

The 5 mA output current is the hard limit for direct drive. The 275 µA quiescent supply current is low enough for battery-powered designs.

Sourcing and lifecycle

The LM4120IM5X-3.3/NOPB carries an Active product status and is ROHS3 compliant, so there's no last-time-buy pressure.

Frequently asked questions

What is the datasheet for LM4120IM5X-3.3/NOPB?

The datasheet contains all key specs (tolerance, noise, temperature coefficient) needed to validate the part fits the design.

Where can I buy LM4120IM5X-3.3/NOPB in stock?

Sourcing buyers need immediate inventory and price to fill a BOM line or avoid production delays.

Is LM4120IM5X-3.3/NOPB obsolete or active?

Brokers and buyers must know if the part is end-of-life to plan for last-time buys or find replacements.

What is the pinout of LM4120IM5X-3.3/NOPB in SOT-23-5?

Design engineers and techs need pin mapping to verify PCB layout and avoid board spin.

What is a replacement for LM4120IM5X-3.3/NOPB?

If the part is out of stock or EOL, a compatible alternative keeps the design or repair moving.

What is the price of LM4120IM5X-3.3/NOPB in 1000 piece quantities?

Volume pricing directly impacts BOM cost; buyers need accurate quotes for budgeting.
