Product details
Overview
AP130-18YRG-13 from Diodes Incorporated is a fixed 1.8V, 300mA low-dropout linear regulator in SOT89R-3L package, featuring 400mV dropout at full load, ±2% output voltage accuracy, and 50µA quiescent current. It integrates thermal shutdown, current limit with fold-back, and operates across 2.7V–5.5V input range for battery-powered peripherals and embedded I/O rails.
For engineers reviewing the AP130-18YRG-13 datasheet, AP130-18YRG-13 pinout, AP130-18YRG-13 application, or AP130-18YRG-13 equivalent, key selection criteria include dropout performance under 300mA load, stability with 10µF output capacitance, thermal resistance (θJC = 23°C/W), and compatibility with SC59R/SOT23/SOT89 variants in space-constrained designs.
Technical Context
The AP130-18YRG-13 uses a PMOS pass element with 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current. Its bandgap-referenced error amplifier delivers fast transient response and tight load regulation (±40mV over 1–300mA).
Internal protection includes thermal shutdown triggered at TJ ≥ 125°C and current limiting with short-circuit fold-back (150–300mA). The device requires only a 10µF ceramic output capacitor for stability and achieves 58dB PSRR at 100Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±2% - ensures stable core supply for 1.8V logic and low-power microcontrollers. |
| Max Output Current | 300mA - supports moderate-power peripherals like USB PHYs or sensor interfaces without derating. |
| Dropout Voltage | 400mV (typ) at 300mA - enables operation down to 2.2V input, critical for single-cell Li-ion or Li-poly systems. |
| Quiescent Current | 50µA (typ) - minimizes standby power loss in always-on battery-backed circuits. |
| PSRR | 58dB at 100Hz - suppresses ripple from noisy switchers or shared DC-DC rails feeding mixed-signal ICs. |
| Thermal Resistance θJC | 23°C/W - allows direct heat transfer to PCB copper in SOT89R-3L, supporting continuous 300mA at +85°C ambient. |
| Protection Features | Current limit with fold-back + thermal shutdown - prevents latch-up and permanent damage during overload or poor heatsinking. |
Pinout & Package
SOT89R-3L package: 3-pin surface-mount, lead-free, green molding compound; exposed tab for thermal conduction; footprint matches JEDEC TO-243AA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: GND | Ground reference | Primary return path for load current and internal bias; must connect to low-impedance ground plane for stability and thermal dissipation. |
| 2: IN | Input voltage supply | Accepts 2.7–5.5V; requires ≥1µF input capacitor near pin to suppress source impedance during load transients. |
| 3: OUT | Regulated output | Delivers fixed 1.8V; requires ≥10µF ceramic capacitor to ground for phase margin and transient recovery. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS pass transistor | Zero gate drive current enables 50µA IQ independent of load - ideal for energy harvesting and coin-cell applications. |
| Fast transient response | Stabilizes within <10µs after 100mA step load change - maintains voltage integrity for burst-mode digital loads. |
| Short-circuit fold-back | Limits output current to 150–300mA during fault, reducing power dissipation and junction temperature rise. |
| Green RoHS-compliant packaging | SOT89R-3L with halogen-free, antimony-free molding compound - meets IPC-1752A Class 3 environmental compliance. |

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-18W5G-7 | 200mA rated, SOT23-5 package, 350mV dropout at 200mA, 65µA IQ | Lower current capacity; requires different footprint and layout; better suited for space-constrained sub-200mA rails | Select when board area is critical and load never exceeds 200mA; verify thermal margin with θJA = 200°C/W. |
| MCP1700T-1802E/TT | 250mA rated, SOT23-3 package, 600mV dropout at 250mA, 1.6µA IQ (ultra-low) | Higher dropout limits minimum input to 2.4V; ultra-low IQ favors long-term battery monitoring over high-current bursts | Prefer for coin-cell applications >5-year life where peak load ≤250mA and input stays ≥2.4V. |
Compared with AP2202K-18W5G-7 and MCP1700T-1802E/TT, the AP130-18YRG-13 uniquely balances 300mA capability, 400mV dropout, and 50µA IQ in a thermally robust SOT89R-3L package-making it optimal for mid-power embedded systems requiring both efficiency and ruggedness.

FAQ
What is the minimum input voltage required for AP130-18YRG-13 to maintain regulation at 300mA?
The AP130-18YRG-13 requires VIN ≥ VOUT + VDROP = 1.8V + 0.4V = 2.2V to sustain 300mA output. Per datasheet, guaranteed operation starts at 2.7V input, but functional dropout behavior is characterized down to 2.2V with pulsed testing. Below 2.7V, line regulation degrades slightly but remains within ±2% up to 300mA if junction temperature is controlled.
Can AP130-18YRG-13 be used with ceramic output capacitors smaller than 10µF?
No-datasheet specifies a minimum 10µF ceramic capacitor at the output for stability across all operating conditions. Using <10µF risks oscillation or poor transient response due to insufficient phase margin. Equivalent series resistance (ESR) must be <100mΩ; X5R or X7R dielectrics are recommended.
How does the short-circuit fold-back protection behave under sustained fault conditions?
Under short-circuit, output current drops to 150–300mA (typ), reducing power dissipation and preventing thermal runaway. Junction temperature rises until thermal shutdown activates at ~125°C, then the device latches off until cooldown. After reset, it resumes normal operation if fault is cleared.
Is the SOT89R-3L package of AP130-18YRG-13 pin-compatible with standard SOT89-3L?
No-the SOT89R-3L has reversed pinout: Pin 1 = GND, Pin 2 = IN, Pin 3 = OUT, whereas standard SOT89-3L is Pin 1 = OUT, Pin 2 = GND, Pin 3 = IN. Layouts must be verified against Diodes' AP02007 land pattern; mixing footprints causes immediate functional failure.
