Product Details
SC4216HSETRT - 3 A Adjustable Low-Dropout Regulator
Semtech Corporation SC4216HSETRT is a very-low-input positive linear regulator with enable control in an 8-lead SOIC exposed-die-pad package.
The manufacturer identifies this exact tape-and-reel code as the SC4216H SOIC-8-EDP version.
Overview
SC4216HSETRT supports loads up to 3 A where the input supply is close to the required output voltage. The output can be adjusted with a feedback divider or set to 0.5 V by connecting FB to VO. An enable input reduces consumption in shutdown. The exposed pad must be connected to ground for electrical reference and heat removal. Verify input headroom and PCB thermal design at the intended load.
Key Advantages
Recommended VIN extends down to 1.45 V, subject to output-voltage headroom.
Up to 3 A is supported within electrical and thermal limits.
Semtech highlights approximately 500 mV dropout at 3 A under the stated test conditions.
The EN input can turn off the regulator; shutdown current is 10 µA typical at 5.5 V VIN and EN low.
Feature Summary
Use FB tied to VO for the 0.5 V setting, or an external divider for a higher regulated rail.
The recommended input range is 1.45 V to 5.5 V; at full load, allow at least approximately 0.5 V above the selected output.
Overcurrent and overtemperature protection are provided.
Semtech calls for at least 4.7 µF ceramic input bypass and 10 µF directly at the output.
Package & Footprint
Semtech's exact ordering table identifies SOIC-8-EDP, an eight-lead SOIC with an exposed die pad. LCDChip registers the package as 8-SOIC (0.154 inch, 3.90 mm width) Exposed Pad and uses the canonical name 8-SOIC Exposed Pad. Follow the Semtech mechanical drawing for body dimensions and the thermal-pad land pattern.
- Connect the exposed die pad and pin 8 to the ground plane.
- Use multiple thermal vias below the pad where the board design requires them.
- Place the input and output capacitors close to their pins.
The package JPG is illustrative; its top view does not show the underside exposed pad. Confirm the land pattern in Semtech's controlled package drawing.
Pin Functions
Semtech's SC4216H pin-description table gives the following assignments for SOIC-8-EDP:
Enable input; below 0.4 V turns the regulator off. Leave open or connect to VIN to enable.
Input supply; place at least 4.7 µF ceramic bypass close to this pin.
Regulated output; place at least 10 µF close to this pin.
Feedback; connect to VO for 0.5 V or use a divider for adjustable output.
Reference ground; connect to the exposed pad at the IC.
No connection.
Thermal pad; connect to the ground plane with suitable vias.

Replacement Considerations
Any alternative must match the selected output range, 3 A load, 1.45 V to 5.5 V input envelope, enable behavior, feedback reference, pinout, exposed-pad ground connection and thermal limits. The SC4216 and SC4216H are different family members; compare their electrical tables and exact ordering codes before substitution. No LCDChip internal alternative link is asserted without an exact API match.
Manufacturer Information
Semtech's SC4216H product page and Rev. 3.0 data sheet identify SC4216HSETRT as the lead-free SOIC-8-EDP tape-and-reel option. The data sheet supplies the pin assignments, electrical conditions and capacitor guidance used here. Check the current Semtech lifecycle and controlled revision when qualifying the device.
Applications
Local high-current rail from a low-voltage source.
Point-of-load regulation with suitable thermal copper.
Adjustable supply for circuits with tight input-to-output headroom.
Enabled 3 A rail after capacitor and junction-temperature validation.
Quality & Authenticity
Verify the full SC4216HSETRT order code, SOIC-8-EDP body, Semtech marking, lot traceability and lead-free status against manufacturer records for the actual shipment. The ordering note specifies WEEE and RoHS compliance and a 2,500-piece tape-and-reel carrier.
FAQ
Is the output fixed at 0.5 V?
FB tied to VO sets 0.5 V. An external feedback divider sets a higher output within the supported design envelope.
How is the regulator disabled?
Pull EN below 0.4 V; the part is enabled when EN is left open.
What connects to the exposed pad?
Connect the pad to ground with a suitable thermal path and tie it to pin 8 at the IC.
Is 1.45 V input sufficient for every output setting at 3 A?
No. The input must also exceed the chosen output by the required load-dependent dropout margin.
Engineering Notice
Validate worst-case input sag, feedback-divider accuracy, load-dependent dropout, input and output capacitor effective values, enable state and exposed-pad heat spreading. Do not infer continuous operating limits from absolute-maximum ratings or from a generic package illustration. Use the current Semtech data sheet and the actual PCB stackup for final qualification.
