Product details
Overview
AP130-30YL-13 from Diodes Incorporated is a fixed 3.0V, 300mA low-dropout linear regulator in SOT89-3L 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 stable power delivery in space-constrained battery-powered systems.
For engineers reviewing the AP130-30YL-13 datasheet, AP130-30YL-13 pinout, AP130-30YL-13 application, or AP130-30YL-13 equivalent, key selection criteria include dropout voltage under 300mA load, thermal resistance (θJA = 100°C/W), output stability with 10µF ceramic output capacitor, and compatibility with 2.7–5.5V input rails in portable electronics.
Technical Context
The AP130-30YL-13 uses a PMOS pass transistor with internal 1.5Ω RON, enabling ultra-low quiescent current (50µA typ.) independent of load. Its error amplifier and bandgap reference deliver tight line regulation (0.1–0.3%/V) and load regulation (30–40mV over 1–300mA).
Protection circuitry includes thermal shutdown triggered at TJ ≥ 125°C and current limit (350–450mA), with fold-back short-circuit response limiting ISC to 150–300mA. PSRR reaches 58dB at 100Hz with 1µF/10µF input/output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% - ensures stable core logic supply for 3.3V-tolerant microcontrollers without external feedback. |
| Max Output Current | 300mA continuous - supports moderate-power peripherals like USB PHYs or small LCD drivers. |
| Dropout Voltage | 400mV typ. at 300mA - enables operation down to 3.4V input while maintaining regulated 3.0V output. |
| Quiescent Current | 50µA typ. at zero load - minimizes standby power loss in always-on battery applications. |
| PSRR | 58dB at 100Hz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Thermal Resistance θJA | 100°C/W (SOT89-3L, no heatsink) - requires ≤25°C ambient rise at full 300mA load for safe junction temperature. |
| Protection | Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up or 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: 4.50mm × 2.90mm × 1.60mm (L×W×H), 1.50mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output node | Delivers fixed 3.0V to load; requires ≥10µF ceramic capacitor to ground for stability. |
| 2 (GND) | Ground reference and thermal pad | Primary return path and thermal conduction path to PCB copper; must be soldered to ≥1.5cm² thermal pad. |
| 3 (IN) | Unregulated input supply | Accepts 2.7–5.5V; requires ≥1µF bypass capacitor near pin to suppress high-frequency noise. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS pass element | Zero gate drive current eliminates base-current dependency, enabling stable 50µA IQ across load range. |
| Fast transient response | Stabilizes within <10µs after 100mA step load change due to optimized error amplifier bandwidth and 10µF COUT. |
| Green molding compound | Halogen-free (no Br/Sb), RoHS-compliant package meets IPC-1752 environmental requirements. |
| Internal current limit | 350–450mA threshold with fold-back reduces power dissipation during sustained short-circuit events. |
| Low thermal resistance | θJA = 100°C/W (SOT89-3L) allows 300mA operation without external heatsink in ≤25°C ambient. |
Applications
| Wireless Sensor Node | USB Peripheral Controller |
|---|---|
|
Use Scenario: Sub-1W IoT sensor node powered by single Li-ion cell (3.0–4.2V) with BLE radio and MCU. IC Role / Device Role / Timing Role: Primary 3.0V rail regulator supplying MCU core, RF transceiver, and ADC reference. Use Value: 400mV dropout enables >90% battery utilization down to 3.4V; 50µA IQ extends shelf life beyond 5 years in sleep mode. |
Use Scenario: External USB 2.0 hub IC requiring clean 3.0V supply from 5V bus-powered source. IC Role / Device Role / Timing Role: Post-regulator filtering switch-mode ripple before USB PHY analog blocks. Use Value: 58dB PSRR at 100Hz attenuates DC-DC switching noise, reducing USB packet error rate by >3 orders of magnitude. |
| Industrial HMI Display | SD Card Interface Power |
|
Use Scenario: 3.5-inch resistive touchscreen display with ARM Cortex-M4 MCU and backlight driver. IC Role / Device Role / Timing Role: Dedicated 3.0V supply for display controller and touch digitizer ASIC. Use Value: ±2% output accuracy maintains consistent gamma correction; 30–40mV load regulation prevents flicker during dynamic screen updates. |
Use Scenario: Embedded SD card slot in medical data logger using FAT32 file system. IC Role / Device Role / Timing Role: Isolated 3.0V supply decoupled from main system rail to prevent SD command corruption during MCU resets. Use Value: Thermal shutdown prevents latch-up during hot-plug insertion; fold-back current limits inrush surge to <200mA. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3002E/TO | 250mA max output, 175mV dropout at 250mA, 1.6µA IQ - lower current, much lower IQ, higher precision (±0.4%). | Optimized for ultra-low-power coin-cell devices; insufficient for 300mA loads. | Select when standby current dominates design and load never exceeds 250mA. |
| TPS73030DBVR | 300mA output, 120mV dropout at 300mA, 170µA IQ - lower dropout, higher IQ, tighter accuracy (±1%). | Better suited for 3.3V→3.0V post-regulation where input headroom is limited. | Select when input voltage is constrained (e.g., 3.3V rail) and 120mV dropout is critical. |
Compared with MCP1700-3002E/TO and TPS73030DBVR, the AP130-30YL-13 balances mid-range current capability, moderate dropout, and ultra-low IQ - making it optimal for cost-sensitive, battery-powered applications needing reliable 300mA delivery without aggressive headroom constraints.

FAQ
What is the minimum input voltage required for AP130-30YL-13 to maintain 3.0V output at 300mA?
The AP130-30YL-13 requires VIN ≥ 3.4V to sustain 3.0V output at 300mA load, based on its typical 400mV dropout voltage. At lower input voltages, output drops linearly; operation below 2.7V input is outside specified operating conditions and may cause regulation failure or thermal shutdown.
Can AP130-30YL-13 be used with ceramic output capacitors?
Yes-AP130-30YL-13 is stable with ≥10µF X5R/X7R ceramic capacitors on the output, as confirmed in the datasheet's Functional Descriptions section. The device does not require ESR-based damping, unlike older LDOs, due to its internal compensation optimized for low-ESR ceramics.
Is the SOT89-3L package thermally adequate for continuous 300mA operation?
Yes, when mounted per Diodes' recommended land pattern (≥1.5cm² copper pour on layer 1 connected to pin 2), the SOT89-3L achieves θJA ≈ 100°C/W. At 300mA and 3.4V input, power dissipation is 120mW, resulting in ~12°C junction rise above ambient-well within the -40°C to +125°C operating range.
Does AP130-30YL-13 support reverse polarity or reverse current protection?
No-the AP130-30YL-13 lacks intrinsic reverse-voltage or reverse-current blocking. If input can fall below output (e.g., during hot-swap), an external Schottky diode between IN and OUT is required to prevent backfeed and potential damage to upstream circuitry.
