Product details

Overview

AP130-35YG-13 from Diodes Incorporated is a fixed-output 3.5V, 300mA low-dropout linear regulator in SOT89-3L package, featuring 400mV dropout at full load, ±2% output voltage accuracy, and 50µA quiescent current. It integrates PMOS pass element with no base current draw, thermal shutdown, and current-limit protection-designed for battery-powered peripherals requiring stable low-noise supply.

For engineers reviewing the AP130-35YG-13 datasheet, AP130-35YG-13 pinout, AP130-35YG-13 application, or AP130-35YG-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θ_JA = 100°C/W), green RoHS-compliant packaging, and compatibility with 10µF minimum output capacitance for stability.

Technical Context

The AP130-35YG-13 employs a PMOS pass transistor with internal 1.5Ω R_ON, enabling ultra-low quiescent current (50µA typ.) independent of load. Its bandgap reference and error amplifier deliver tight load regulation (±40mV over 1–300mA) and line regulation (0.3%/V).

Protection circuitry includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered at T_J ≥ 125°C. The device operates across –40°C to +85°C ambient, with PSRR of 58dB at 100Hz and fast transient response optimized for portable applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.5V ±2% - ensures stable rail for 3.3V-tolerant logic and RF front-ends without external feedback.
Max Output Current	300mA continuous - supports moderate-power peripherals like USB transceivers or sensor hubs.
Dropout Voltage	400mV @ 300mA - enables operation down to 3.9V input, critical for single-cell Li-ion (3.0–4.2V) systems.
Quiescent Current	50µA typ. - minimizes standby power loss in always-on battery-backed modules.
PSRR	58dB @ 100Hz - suppresses switching noise from upstream DC/DC converters feeding the LDO input.
Thermal Resistance θ_JA	100°C/W (SOT89-3L, no heatsink) - defines maximum power dissipation (315mW @ ΔT=31.5°C) under standard PCB layout.
Protection Features	Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up or destruction during fault conditions.

Pinout & Package

SOT89-3L package: 3-pin surface-mount, thermally enhanced plastic outline with exposed tab (pin 2 connected to GND for optimal heat transfer). Dimensions: 4.5 × 2.5 × 1.5mm (L×W×H), lead-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT)	Regulated output node	Delivers stable 3.5V; requires ≥10µF ceramic capacitor to ground for loop stability and transient response.
2 (GND)	Ground reference & thermal pad	Primary return path and main thermal conduction path to PCB copper; must be soldered to ≥1cm² thermal pad.
3 (IN)	Unregulated input supply	Accepts 2.7–5.5V; requires local 1µF bypass capacitor near pin to suppress high-frequency noise and input sag.

Key Features

Feature	Design Value
PMOS pass element	Zero gate drive current eliminates base-current dependency, enabling stable IQ across input voltage range.
Fast transient response	Stabilizes within <10µs after 100mA step load change-critical for burst-mode digital loads.
Green molding compound	Halogen-free (no Br/Sb), compliant with IPC-4101D/21, reduces environmental impact without sacrificing moisture resistance.
Internal current limit	450mA typical trip threshold with fold-back behavior-limits fault power dissipation to safe levels during shorts.
Thermal shutdown hysteresis	Re-enables ~20°C below trip point (125°C)-prevents oscillation during sustained overload near thermal limit.

Applications

Wireless LAN Modules

USB Peripheral Controllers

Use Scenario: Powering 2.4GHz WLAN chipsets (e.g., RTL8189ES) in compact IoT gateways with single-cell Li-ion input.

IC Role / Device Role / Timing Role: Primary 3.5V supply regulator delivering clean, low-noise voltage to RF and baseband sections.

Use Value: 400mV dropout allows >90% battery utilization; 58dB PSRR prevents DC/DC ripple from degrading EVM.

Use Scenario: Supplying VCC to USB 2.0 hub controllers (e.g., TUSB2036) in docking stations with mixed 3.3V/5V rails.

IC Role / Device Role / Timing Role: Local post-regulator converting noisy 5V bus to precise 3.5V for analog PHY biasing.

Use Value: ±2% accuracy maintains USB suspend/resume timing margins; thermal shutdown protects against connector short events.

Industrial Sensor Nodes

Optical Drive Logic Boards

Use Scenario: Powering low-power microcontrollers (e.g., STM32L0) and analog sensors in battery-operated condition monitoring nodes.

IC Role / Device Role / Timing Role: Main system regulator enabling ultra-low-power sleep modes via 50µA quiescent current.

Use Value: Enables >5-year battery life in 10-second wake-up intervals; load regulation ≤40mV preserves ADC reference stability.

Use Scenario: Providing 3.5V bias to servo motor drivers and laser diode control ICs on CD/DVD drive mainboards.

IC Role / Device Role / Timing Role: Secondary LDO isolating sensitive analog circuits from digital switching noise on shared 5V rail.

Use Value: Fold-back current limiting prevents thermal runaway during lens actuator stall; SOT89-3L's θ_JA=100°C/W sustains 300mA under board-level airflow constraints.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-output LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP2202K-3.3TRG1	3.3V output, 300mA, SOT23-5 package, higher IQ (85µA), no fold-back current limit	Lacks short-circuit fold-back; less suitable for intermittent short-circuit risk environments	Select when footprint space is constrained and 3.3V (not 3.5V) matches system rail requirements
MCP1700T-3502E/TT	3.5V output, 250mA, SOT23-3, 1.6µA IQ, no thermal shutdown	Lower IQ but reduced current capability and missing thermal protection	Prefer only for ultra-low-power, low-duty-cycle applications where thermal faults are physically impossible

Compared with AP130-35YG-13, AP2202K-3.3TRG1 trades output voltage and package size for slightly higher quiescent current and reduced fault protection, while MCP1700T-3502E/TT sacrifices current rating and thermal safety for nanoamp-level standby consumption-neither replicates the balanced 300mA/3.5V/thermal+foldback profile of the AP130.

FAQ

What is the minimum output capacitance required for stability with AP130-35YG-13?

The AP130-35YG-13 requires a minimum 10µF ceramic capacitor from OUT to GND for guaranteed stability across all operating conditions. This value is specified in the Functional Descriptions section of DS31027 Rev. 8-2 and validated by phase margin testing at 300mA load. Using lower values may cause oscillation or degraded transient response.

Can AP130-35YG-13 operate with an input voltage below 2.7V?

No. The absolute minimum input voltage is 2.7V per Recommended Operating Conditions (VIN min = 2.7V). Below this, regulation fails and output voltage drops proportionally. At 2.5V input, even with zero load, VOUT falls below 3.5V due to internal reference and error amplifier headroom limitations.

Is the SOT89-3L package of AP130-35YG-13 thermally enhanced?

Yes. The SOT89-3L package features an exposed thermal pad on the underside (connected to pin 2/GND), enabling direct thermal conduction to the PCB. With proper 1cm² copper pour, θ_JA is rated at 100°C/W-significantly lower than SC59 (250°C/W) or SOT23 (200°C/W) variants.

Does AP130-35YG-13 support reverse polarity protection?

No. The AP130-35YG-13 lacks integrated reverse-voltage protection. Applying negative voltage to IN or OUT relative to GND may damage the PMOS pass transistor or bandgap circuitry. External protection (e.g., series Schottky diode or dedicated reverse-protection IC) is required in systems prone to polarity reversal.
