Design notes

Use the rating in context

Use the cited operating conditions for SGM2019-3.3YN5G/TR; do not convert an absolute maximum, headline rating or family-level value into an unconditional board-level guarantee.

The displayed package image is representative and does not prove body marking, date code or shipment lot.

SGMICRO currently marks this exact order code Not Recommended for New Design; source buyers should confirm a supported alternative for new designs. Output accuracy is ±2.5% at 25 °C and 0.1 mA load. Dropout is 270 mV typical at 300 mA and 25 °C, noise is 30 µVrms typical from 10 Hz to 100 kHz, and PSRR is 74 dB typical at 1 kHz under the documented capacitor and load conditions.

Technical and ordering FAQ

Questions buyers ask about SGM2019-3.3YN5G/TR

Answers distinguish the IC itself from assembled modules and keep absolute limits separate from normal operating conditions.

What package does SGM2019-3.3YN5G/TR use?

SGM2019-3.3YN5G/TR is recorded in SOT-23-5. Confirm the complete suffix and packing in the quotation.

What is the documented power-supply rejection?

The cited manufacturer record lists 74 dB. Apply the source's test and operating conditions.

How should the output noise be interpreted?

The normalized catalog value is 30 µVrms. The linked evidence controls its exact conditions and revision.

Does this page prove current SGM2019-3.3YN5G/TR stock?

No. Technical evidence identifies the device; stock, date code, price, MOQ and lead time require a current verified offer or quotation.

Can SGM2019-3.3YN5G/TR be replaced by a similar part without review?

No automatic drop-in claim is made. Compare electrical limits, package, pinout, functions and qualification before substitution.

Catalog relationships
