Product details
Overview
AP130-33YRL-13 from Diodes Incorporated is a fixed 3.3V, 300mA low-dropout linear regulator in SOT89-3L package with 400mV dropout at full load, 50µA quiescent current, and ±2% output voltage accuracy-designed for battery-powered wireless modules requiring stable low-noise supply under variable load.
For engineers reviewing the AP130-33YRL-13 datasheet, AP130-33YRL-13 pinout, AP130-33YRL-13 application, or AP130-33YRL-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θJA = 100°C/W), PSRR of 58dB at 100Hz, and guaranteed short-circuit fold-back protection.
Technical Context
The AP130-33YRL-13 uses a PMOS pass element with internal 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.
Integrated current-limit (450mA typ) and thermal shutdown circuitry activate under fault conditions, while short-circuit fold-back reduces power dissipation during output shorts. Stability requires ≥10µF output capacitance per functional description.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% - ensures compatible logic-level supply for 3.3V microcontrollers and RF ICs |
| Max Output Current | 300mA continuous - supports moderate-power peripherals like USB PHYs or Wi-Fi transceivers |
| Dropout Voltage | 400mV at 300mA - enables operation down to 3.7V input, suitable for single-cell Li-ion systems |
| Quiescent Current | 50µA typ - minimizes standby power loss in always-on battery applications |
| PSRR | 58dB at 100Hz - suppresses ripple from noisy switchers or shared DC rails |
| Thermal Resistance θJA | 100°C/W (SOT89-3L, no heatsink) - defines safe power dissipation limit of ~330mW at 85°C ambient |
| Protection Features | Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up or destruction during overload |
Pinout & Package
SOT89-3L package: 3-pin surface-mount, thermally enhanced leadframe, 4.5mm × 2.5mm footprint, exposed tab for improved heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers stable 3.3V to load; requires ≥10µF ceramic capacitor to ground for stability |
| 2 (GND) | Ground reference | Low-impedance return path for load and internal bias; connects to thermal pad for heat dissipation |
| 3 (IN) | Input supply | Accepts 2.7–5.5V; must be decoupled with ≥1µF capacitor near pin to suppress transients |
Key Features
| Feature | Design Value |
|---|---|
| PMOS pass transistor | Eliminates base current draw, enabling 50µA IQ independent of load current |
| Fast transient response | Maintains <±15mV output deviation during 100mA step load changes (per typical curves) |
| Load regulation | ≤40mV variation from 1mA to 300mA load - ensures consistent voltage for analog sensors |
| Green molding compound | Halogen-free, RoHS-compliant package (no Br/Sb) - meets environmental compliance for CE-marked devices |
| Lead-free finish | 100% matte tin plating - compatible with standard Pb-free reflow profiles (J-STD-020) |
Applications
| Wireless Transceiver Power | USB Peripheral Regulation |
|---|---|
Use Scenario: Powering 2.4GHz BLE or Zigbee SoCs with pulsed transmit current up to 250mA. IC Role / Device Role / Timing Role: Primary LDO supplying VDD_IO and VDD_CORE rails. Use Value: 400mV dropout allows direct use of single-cell Li-ion (3.0–4.2V); 58dB PSRR reduces RF noise coupling into sensitive analog front-ends. |
Use Scenario: Regulating 5V USB bus down to clean 3.3V for USB-UART bridges or HID controllers. IC Role / Device Role / Timing Role: Post-regulator isolating digital noise from upstream switching supply. Use Value: Low 50µA quiescent current preserves host port power budget; ±2% accuracy ensures USB spec compliance for VBUS-sensing logic. |
| Industrial Sensor Node | Embedded Microcontroller Core Supply |
Use Scenario: Powering low-power ADCs, temperature sensors, and LoRaWAN modems in battery-operated field nodes. IC Role / Device Role / Timing Role: Main system regulator enabling >5-year battery life on coin cells or AA alkalines. Use Value: 50µA IQ and 300mA capability support deep-sleep wake cycles without brownout; thermal shutdown protects against enclosure overheating. |
Use Scenario: Supplying 3.3V core voltage to ARM Cortex-M0+ MCUs in space-constrained industrial controllers. IC Role / Device Role / Timing Role: Local point-of-load regulator adjacent to MCU VDD pins. Use Value: SOT89-3L's 100°C/W θJA and exposed thermal pad enable reliable operation at 85°C ambient without heatsink; fast transient response prevents reset during code execution bursts. |
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 |
|---|---|---|---|
| MCP1700-3302E/TO | 250mA max output, 175mV dropout at 250mA, 1.6µA IQ - lower current, much lower IQ, higher cost | Limited to sub-250mA loads; better for ultra-low-power sleep modes but unsuitable for 300mA burst loads | Select when standby current dominates design; avoid if peak load exceeds 250mA |
| TPS7333QDBVRQ1 | 300mA, 350mV dropout at 300mA, 250µA IQ, AEC-Q100 qualified - automotive-grade, higher IQ, tighter temp range | Qualified for automotive (-40°C to +125°C), but overqualified and more expensive for commercial applications | Choose only for automotive programs requiring AEC-Q100; otherwise, AP130-33YRL-13 offers better cost/performance balance |
Compared with MCP1700-3302E/TO and TPS7333QDBVRQ1, the AP130-33YRL-13 delivers optimal trade-off between 300mA capability, 400mV dropout, and 50µA IQ in a cost-effective SOT89-3L package-making it ideal for high-volume consumer and industrial portable electronics where automotive qualification is unnecessary.

FAQ
What is the minimum input voltage required for AP130-33YRL-13 to maintain regulation at 300mA?
The AP130-33YRL-13 requires VIN ≥ VOUT + VDROP = 3.3V + 0.4V = 3.7V to sustain 300mA output current while maintaining regulation within ±2%. Below 3.7V, output voltage drops linearly with input; the device remains functional but exits regulation.
Can AP130-33YRL-13 operate with ceramic output capacitors?
Yes - the AP130-33YRL-13 is stable with ceramic capacitors ≥10µF and ESR ≥10mΩ. The datasheet specifies ceramic compatibility and recommends X5R/X7R dielectrics; no series resistor is needed for phase margin.
Does AP130-33YRL-13 require an input capacitor?
Yes - a minimum 1µF ceramic capacitor placed ≤5mm from the IN pin is required to suppress high-frequency noise and prevent oscillation during load transients, as confirmed by the Typical Application Circuit and Functional Descriptions section.
Is AP130-33YRL-13 pin-compatible with other SOT89-3L LDOs?
No - AP130-33YRL-13 has OUT-GND-IN pinout (Y code), which differs from common IN-GND-OUT configurations. Substituting without board revision risks reverse polarity and immediate failure; verify pin mapping before replacement.
