Product details
Overview
AP130-30WL-7 from Diodes Incorporated is a 300mA fixed-output 3.0V low-dropout linear regulator in SC59 package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates PMOS pass element with no base current draw, thermal shutdown, and fold-back short-circuit protection-designed for battery-powered portable electronics requiring stable low-noise voltage regulation.
For engineers reviewing the AP130-30WL-7 datasheet, AP130-30WL-7 pinout, AP130-30WL-7 application, or AP130-30WL-7 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (250°C/W in SC59), output voltage tolerance, PSRR (58dB @100Hz), and compatibility with 1µF input / 10µF output capacitor stabilization.
Technical Context
The AP130-30WL-7 employs a PMOS pass transistor architecture enabling zero gate-drive current and inherently low quiescent consumption. Its error amplifier uses a 1.08V internal bandgap reference to regulate output against line (0.1–0.3%/V) and load (30–40mV) variations.
Protection circuitry includes thermal shutdown triggered at junction temperatures exceeding +125°C and current-limiting with fold-back behavior that reduces short-circuit current to 150–300mA-preventing latch-up and enabling safe recovery under fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% - ensures stable core logic supply for 3.3V-tolerant microcontrollers and peripherals. |
| Max Output Current | 300mA continuous - supports moderate-power sensors, RF modules, and USB peripheral ICs. |
| Dropout Voltage | 400mV typ. at 300mA - enables operation down to 3.4V input, critical for single-cell Li-ion or dual-cell alkaline systems. |
| Quiescent Current | 50µA typ. at zero load - minimizes standby power loss in always-on battery applications. |
| PSRR | 58dB @100Hz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Thermal Resistance θJA | 250°C/W (SC59) - defines maximum power dissipation (≤300mW) before thermal shutdown activates at ambient ≤85°C. |
| Line Regulation | 0.1–0.3%/V - maintains output stability across input voltage sag during battery discharge or transient load steps. |
| Load Regulation | 30–40mV over 1–300mA - ensures consistent voltage delivery across dynamic current profiles in portable devices. |
Pinout & Package
AP130-30WL-7 is housed in the SC59 surface-mount package (2.90 × 1.30 × 0.95 mm), optimized for space-constrained PCB layouts. The package features gull-wing leads and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Power Input | Accepts 2.7–5.5V input; requires ≥1µF ceramic decoupling close to pin to prevent oscillation. |
| 2 (OUT) | Regulated Output | Delivers fixed 3.0V; requires ≥10µF low-ESR output capacitor for loop stability and transient response. |
| 3 (GND) | Ground Reference | Common return path for error amplifier, bandgap, and pass device; must connect to low-impedance ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | Zero gate drive current eliminates base current loss-enabling ultra-low IQ without sacrificing output drive capability. |
| Fold-Back Current Limit | Reduces short-circuit current to 150–300mA during fault, limiting power dissipation and enabling self-recovery without external reset. |
| Fast Transient Response | Maintains <±1% output deviation during 100mA load steps due to high-gain error amplifier and optimized compensation. |
| Thermal Shutdown | Activates at TJ ≥ +125°C and holds until junction cools by ≥15°C-prevents permanent silicon damage under sustained overload. |
| Green Molding Compound | Halogen-free (no Br/Sb) epoxy meets IEC 61249-2-21, supporting environmental compliance in consumer and industrial end products. |
Applications
| Wireless Sensor Node | USB Peripheral Controller |
|---|---|
Use Scenario: Sub-1W IoT sensor node powered by CR2032 or single-cell Li-ion, operating intermittently with deep-sleep cycles. IC Role / Device Role / Timing Role: Primary 3.0V supply for MCU, BLE radio, and analog sensor interface-replacing higher-IQ regulators to extend battery life. Use Value: 50µA quiescent current directly extends shelf life beyond 5 years in storage; 400mV dropout allows operation until battery reaches 3.4V. |
Use Scenario: External USB-to-serial adapter or HID device drawing burst current up to 250mA during data transfer. IC Role / Device Role / Timing Role: Post-regulator cleaning noisy 5V USB bus voltage to clean 3.0V for UART transceivers and EEPROM. Use Value: 58dB PSRR at 100Hz attenuates USB switcher ripple; fast transient response prevents UART framing errors during packet bursts. |
| Industrial Data Logger | Portable Medical Monitor |
Use Scenario: Battery-backed data acquisition unit logging temperature/humidity every 10 seconds in remote field deployments. IC Role / Device Role / Timing Role: Stable 3.0V rail for precision ADC, real-time clock, and flash memory-immune to input voltage sag during SD card writes. Use Value: ±2% output accuracy ensures ADC reference stability; 30–40mV load regulation prevents code shifts during concurrent sensor sampling and storage. |
Use Scenario: Handheld pulse oximeter using optical sensors and analog front-end, powered by rechargeable Li-polymer cell. IC Role / Device Role / Timing Role: Low-noise 3.0V supply for photodiode amplifiers and analog signal chain-minimizing measurement drift and noise floor. Use Value: Low 50µA IQ preserves battery between readings; thermal shutdown protects against enclosure overheating during extended use. |
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 |
|---|---|---|---|
| MCP1700T-3002E/TT (Microchip) | 250mA max output, 175mV dropout @100mA, 2.0µA IQ - lower IQ but reduced current capacity and no fold-back protection. | Suitable only for sub-200mA loads; lacks short-circuit robustness for shared-rail systems with variable downstream impedance. | Select when ultra-low standby power dominates over fault resilience and full 300mA capability. |
| TPS73030DBVR (TI) | 300mA output, 170mV dropout @200mA, 330µA IQ - lower dropout but 6.6× higher quiescent current than AP130-30WL-7. | Better for high-efficiency mid-load operation (>50mA), but degrades battery life in deep-sleep modes where IQ matters most. | Prefer when input voltage margin is tight (<3.2V) and average load exceeds 50mA continuously. |
Compared with MCP1700T-3002E/TT and TPS73030DBVR, AP130-30WL-7 uniquely balances 300mA drive, 400mV dropout, and 50µA IQ-making it optimal for battery-powered systems requiring both peak current headroom and multi-year shelf life.

FAQ
What is the minimum input voltage required for AP130-30WL-7 to maintain regulated 3.0V output at 300mA?
The AP130-30WL-7 requires a minimum input voltage of 3.4V to sustain 3.0V output at full 300mA load, based on its typical 400mV dropout voltage. At lower loads, dropout decreases proportionally-e.g., ~150mV at 100mA-allowing operation down to 3.15V input under light conditions.
Can AP130-30WL-7 be used without an output capacitor?
No. A minimum 10µF low-ESR output capacitor is mandatory for stability, as confirmed in the datasheet's Functional Descriptions section. Omitting it risks oscillation, poor transient response, and potential device failure under load step conditions.
Does AP130-30WL-7 support adjustable output voltage via external resistors?
No. AP130-30WL-7 is a fixed-output variant with internally trimmed 3.0V regulation. Adjustable versions (e.g., AP131 series) exist but require different part numbers and external feedback networks-not compatible with this SC59-packaged device.
How does the fold-back current limit behave during a sustained short circuit?
Under sustained short circuit, AP130-30WL-7 reduces output current to 150–300mA (per Electrical Characteristics table), lowering power dissipation and preventing thermal runaway. Once the fault clears, the device automatically resumes normal regulation without requiring power cycle or external intervention.
