Product details

1.235V fixed reference in a compact 8-TSSOP

The LM385PWRE4-1-2 is a shunt voltage reference from Texas Instruments that delivers a fixed 1.235 V output with ±2% initial tolerance. Packaged in an 8-TSSOP (4.40 mm width), it is suited for precision bias and comparison circuits where a stable, low-power reference is needed. It can source up to 20 mA of output current while requiring only 15 µA minimum cathode current to maintain regulation, making it efficient for battery-powered or low-headroom designs.

Frequently asked questions

What is the exact output voltage of LM385PWRE4-1-2?

Designers need to confirm the reference voltage is 1.2V with ±2% tolerance for circuit validation.

Is LM385PWRE4-1-2 active or obsolete?

Buyers and brokers need to know if the part is still in production before sourcing or stocking.

Where can I buy LM385PWRE4-1-2 in stock?

Sourcing buyers need real-time distributor inventory to fill BOM lines without backorder risk.

What is the difference between LM385PWRE4-1-2 and LM385B-1.2?

Engineers evaluating alternatives need to compare tolerance and packaging before substituting.

What is the package and footprint of LM385PWRE4-1-2?

Layout engineers need the 8-TSSOP package dimensions and recommended land pattern for PCB integration.

Can LM385PWRE4-1-2 be used as a replacement for a failed LM385-1.2 in an existing design?

Maintenance techs need a drop-in replacement with compatible pinout and electrical specs for a quick fix.
