Product details
Overview
AP130-33YL-13 from Diodes Incorporated is a 300mA fixed-output 3.3V low-dropout linear regulator in SOT89-3L package, featuring 400mV dropout at full load, ±2% output accuracy, 50µA quiescent current, and integrated thermal shutdown and current-limit protection. It serves as a primary voltage rail regulator in battery-powered peripherals and embedded I/O subsystems.
For engineers reviewing the AP130-33YL-13 datasheet, AP130-33YL-13 pinout, AP130-33YL-13 application, or AP130-33YL-13 equivalent, key selection criteria include dropout performance under 300mA load, thermal resistance (θJA = 100°C/W), stability with 10µF output capacitance, and compatibility with 2.7–5.5V input sources in space-constrained designs.
Technical Context
The AP130-33YL-13 uses a PMOS pass element with 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current. Its error amplifier and bandgap reference maintain regulation across –40°C to +85°C ambient temperature with <±2% initial output tolerance.
Internal current-foldback short-circuit protection and thermal shutdown activate at junction temperatures exceeding 125°C. Load regulation is specified at ±40mV over 1–300mA, and PSRR reaches 58dB at 100Hz with 1µF/10µF input/output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% - ensures stable logic-level supply for 3.3V microcontrollers and interfaces |
| Max Output Current | 300mA continuous - supports moderate-power digital ICs and sensor interfaces |
| Dropout Voltage | 400mV typ. at 300mA - enables operation down to 3.7V input when powering 3.3V loads from single Li-ion cells |
| Quiescent Current | 50µA typ. at zero load - minimizes standby power loss in always-on battery systems |
| PSRR | 58dB at 100Hz - suppresses low-frequency ripple from switching DC/DC stages upstream |
| Thermal Resistance θJA | 100°C/W (SOT89-3L, no heatsink) - defines maximum power dissipation (300mW) before thermal shutdown at 85°C ambient |
| Protection Features | Current limit (350–450mA), thermal shutdown, short-circuit foldback - prevents latch-up and permanent damage 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 thermal conduction). Dimensions: 4.5mm × 2.5mm × 1.5mm height; recommended land pattern per AP02007.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output node | Delivers stable 3.3V; requires ≥10µF ceramic or tantalum capacitor to ground for loop stability |
| 2 (GND) | Ground reference and thermal pad | Primary return path and main thermal conduction path to PCB copper; must be soldered to ≥1cm² copper pour |
| 3 (IN) | Unregulated input supply | Accepts 2.7–5.5V; requires local 1µF bypass capacitor within 5mm of pin to suppress high-frequency noise |
Key Features
| Feature | Design Value |
|---|---|
| PMOS pass transistor | 1.5Ω RON enables zero gate-drive current, reducing system-level bias network complexity |
| Fast transient response | Stabilizes within 10µs after 100mA load step - maintains clean supply during MCU wake-up or burst-mode communication |
| Green molding compound | Halogen-free (no Br/Sb), RoHS-compliant - meets IPC-1752A material declaration requirements for industrial end equipment |
| Lead-free finish | 100% matte tin plating - compatible with standard SnPb and lead-free reflow profiles (J-STD-020D) |
| Low temperature coefficient | 50–150 ppm/°C output drift - ensures <±30mV variation over –40°C to +85°C operating range |
Applications
| Wireless Sensor Node | USB Peripheral Hub |
|---|---|
|
Use Scenario: Compact battery-powered Zigbee or BLE endpoint with intermittent RF transmission. IC Role / Device Role / Timing Role: Primary 3.3V LDO supplying RF transceiver, MCU, and analog sensor interface.

IC Role / Device Role / Timing Role: Local 3.3V rail generator for USB PHY and hub logic, decoupled from host VBUS. Use Value: 58dB PSRR attenuates 100Hz ripple from upstream DC/DC converter; thermal shutdown prevents overheating during sustained 300mA load. |
| Industrial I/O Module | Embedded Camera Interface |
|
Use Scenario: DIN-rail mounted PLC I/O expansion module with isolated digital inputs and relay drivers. IC Role / Device Role / Timing Role: Secondary regulated supply for optocoupler input conditioning and level-shifting circuitry.

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 | 250mA rated, 350mV dropout at 250mA, SOT23-5 package, higher PSRR (65dB @100Hz) | Limited to lower-current loads; smaller footprint but less thermal margin | Select when board space is constrained and peak load ≤250mA; verify thermal derating on 2-layer PCB |
| MCP1700T-3302E/TT | 250mA rated, 178mV dropout at 250mA, SOT23-3, 3µA quiescent current | Superior light-load efficiency but lower max current and no short-circuit foldback | Prefer for ultra-low-power sleep modes; avoid where sustained 300mA or robust fault protection is required |
Compared with AP130-33YL-13, AP2202K-3.3TRG1 trades current capacity for compactness and higher PSRR, while MCP1700T-3302E/TT prioritizes micropower operation over fault resilience and thermal headroom-making AP130-33YL-13 optimal for balanced 300mA industrial and peripheral applications.

FAQ
What is the minimum input voltage required for stable 3.3V output at 300mA?
The AP130-33YL-13 requires VIN ≥ VOUT + VDROP = 3.3V + 0.4V = 3.7V for full 300mA output. At 2.7V input, output drops below regulation; operation is guaranteed only between 2.7V and 5.5V, with dropout increasing below 3.7V.
Can AP130-33YL-13 operate without an output capacitor?
No. A minimum 10µF output capacitor is mandatory for stability, as confirmed in the Functional Descriptions section. Omitting it causes oscillation and unregulated output; ceramic or tantalum types are acceptable if ESR falls within 0.1–10Ω range.
Is the SOT89-3L package thermally adequate for continuous 300mA operation at 85°C ambient?
Yes, with proper PCB layout: θJA = 100°C/W implies ΔT = 300mA × (3.3V dropout) × 100°C/W ≈ 12°C rise above ambient. Total junction temperature stays at ~97°C-well below the 125°C shutdown threshold.
Does AP130-33YL-13 support reverse polarity protection?
No. The device lacks internal reverse-voltage blocking; applying negative voltage to IN or OUT relative to GND may cause latch-up or permanent damage. External protection diodes are required in systems prone to reverse connection.
