Product Details
SPX5205M5-L/TR - Adjustable 150 mA Low-Noise LDO
MaxLinear SPX5205M5-L/TR is the adjustable-output member of the SPX5205 low-dropout regulator family, rated for up to 150 mA in a 5-pin SOT-23 package.
Electrical limits, adjustable pin assignment, package data, and exact orderable status were checked against the official MaxLinear product page and SPX5205 Rev. L datasheet.
Overview
SPX5205M5-L/TR combines a 2.5 V to 16 V input range with an adjustable output, low dropout, enable control, reverse-battery protection, current limiting, and thermal shutdown. The output is set with two resistors around the internal 1.235 V reference.
Key Advantages
Adjustable rail
The official family range for the adjustable option spans approximately 1.24 V to 15.725 V.
Low dropout
Typical dropout is 210 mV at the rated 150 mA load.
Low-noise option
With the documented bypass and output capacitors, typical integrated noise can be reduced to 40 microvolts RMS.
Power control
The enable input provides a shutdown state with very low quiescent current.
Feature Summary
150 mA capability
Supports loads up to 150 mA when input headroom and thermal conditions are satisfied.
Precision start point
The family specifies 1 percent initial output accuracy under the stated conditions.
Protection functions
Current limiting, thermal shutdown, and reverse-battery protection are integrated.
Compact package
The five-lead SOT-23 format supports space-constrained portable and control designs.
Package & Footprint
MaxLinear specifies the exact orderable in SOT-23-5, JEDEC reference MO-178. The catalog names SC-74A and SOT-753 denote the same five-lead package family. MaxLinear lists nominal package dimensions of 2.90 mm by 1.60 mm by 1.45 mm with 0.95 mm lead pitch.
- Use the current SOT-23-5 mechanical drawing and top-view numbering.
- Place input and output capacitors close to the regulator and ground.
- Keep the adjustment divider and its return short and quiet.
- Evaluate junction temperature using the actual copper layout and ambient conditions.
The registered JPG is checked locally and at the production URL before publication.
Pin Functions
The adjustable SOT-23-5 assignment follows the official top-view diagram.
The fixed-output member uses BYP at pin 1; do not substitute its pin description for this adjustable order code.

Replacement Considerations
A replacement must match the adjustable topology, ADJ/GND/EN/VIN/VOUT pin order, output-current requirement, input range, dropout, enable thresholds, capacitor stability needs, output accuracy, temperature rating, and SOT-23-5 footprint. Fixed-output SPX5205 options are not direct functional substitutes for the adjustable order code.
No internal replacement link is asserted without an exact API-confirmed catalog match and engineering review.
Manufacturer Information
MaxLinear currently lists SPX5205M5-L/TR as active. The exact orderable is the adjustable, lead-free, 1 percent version in SOT-23-5 for -40 degrees C to +125 degrees C operation. The manufacturer package table specifies a 3000-piece reel and MSL 1 at 260 degrees C.
Applications
Portable electronics
Create an adjustable rail in handheld instruments and battery-powered equipment.
Communications equipment
Support low-noise local regulation in radio and telephone circuitry.
Post-regulation
Reduce residual ripple after a switching converter when headroom and dissipation allow.
Embedded control
Supply compact processor, sensor, and interface rails with enable control.
Quality & Authenticity
Verify the complete SPX5205M5-L/TR order code, package marking, SOT-23-5 dimensions, reel label, lead-free and moisture-sensitivity declarations, and lot traceability during incoming inspection. Package appearance alone does not establish authenticity.
FAQ
Is SPX5205M5-L/TR fixed or adjustable?
It is the adjustable-output order code; fixed voltages use an additional voltage suffix.
How is the output voltage selected?
Two resistors set the output around the 1.235 V reference using the manufacturer equation.
Does it require an output capacitor?
Yes. The datasheet requires output capacitance for stability and recommends bench verification of type and value.
Can EN be tied high?
EN may be tied to VIN when the regulator should remain enabled, provided all input limits are observed.
Is the adjustable pinout the same as the fixed version?
Pins 2 through 5 retain their functions, but pin 1 is ADJ on the adjustable part and BYP on fixed versions.
Engineering Notice
Verify the complete resistor-divider calculation, minimum and maximum output, dropout at load, enable behavior, effective capacitor values, loop stability, reverse conditions, and junction temperature in the final design. The SOT-23 thermal result depends strongly on board copper and airflow.
