Product details
Overview
AP130-18YL-13 from Diodes Incorporated is a fixed 1.8V, 300mA low-dropout linear regulator in SOT89-3L package, featuring 400mV dropout at full load, 50µA quiescent current, ±2% output voltage accuracy, and integrated thermal shutdown and current-limit protection. It serves as a primary power supply for low-voltage microcontrollers and RF front-ends in portable electronics.
For engineers reviewing the AP130-18YL-13 datasheet, AP130-18YL-13 pinout, AP130-18YL-13 application, or AP130-18YL-13 equivalent, key selection criteria include dropout performance at 300mA, stability with 10µF output capacitance, thermal resistance (θJA = 100°C/W), and compatibility with SC59/SOT23/SOT89 footprint variants.
Technical Context
The AP130 employs a PMOS pass transistor with 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current across load range. Its bandgap-referenced error amplifier delivers fast transient response and tight load regulation (≤40mV deviation from 1–300mA).
Internal protection circuitry implements short-circuit fold-back limiting (150–300mA) and thermal shutdown triggered at TJ ≥ 125°C. The device operates over –40°C to +85°C ambient with input voltage range 2.7V–5.5V, making it suitable for single-cell Li-ion and multi-cell alkaline systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±2% - ensures stable core voltage for 1.8V I/O and logic circuits |
| Max Output Current | 300mA - supports moderate-power peripherals like USB PHYs and BLE radios |
| Dropout Voltage | 400mV @ 300mA - enables operation down to 2.2V input, compatible with discharged Li-ion cells |
| Quiescent Current | 50µA typical - minimizes standby power loss in battery-backed real-time clocks |
| PSRR | 58dB @ 100Hz - suppresses ripple from switching DC/DC stages upstream |
| Thermal Resistance θJA | 100°C/W (SOT89-3L) - requires minimal PCB copper area for thermal management |
| Protection Features | Current limit + thermal shutdown - prevents latch-up during output short or overload |
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 × 2.6mm × 1.6mm, 1.5mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output node | Delivers stable 1.8V; requires ≥10µF ceramic capacitor to ground for loop stability |
| 2 (GND) | Ground reference & thermal path | Common return for all internal circuitry; soldered pad provides primary heat dissipation path |
| 3 (IN) | Unregulated 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 element | Eliminates base current draw, enabling 50µA IQ independent of load |
| Fast transient response | Stabilizes within <10µs after 100mA load step, critical for burst-mode processors |
| Short-circuit fold-back | Reduces output current to 150–300mA during fault, limiting power dissipation |
| Green molding compound | Halogen-free, RoHS-compliant package meeting IPC-J-STD-020 moisture sensitivity level 3 |
| Fixed-output variants | Eight factory-set voltages (1.5V–3.5V) simplify BOM consolidation and reduce external component count |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1802E/TT (Microchip) | 250mA rated, 175mV dropout @ 250mA, 1.6µA IQ | Limited to lower-current loads; superior IQ but lower thermal margin in SOT23 | Select when ultra-low standby current dominates over output current capability |
| TPS70618DRVR (TI) | 200mA rated, 230mV dropout @ 200mA, 1.3µA IQ, enable pin | Requires external enable control; smaller SOT23 footprint but no thermal pad | Select when system-level power sequencing is required and 200mA suffices |
Compared with MCP1700T-1802E/TT and TPS70618DRVR, AP130-18YL-13 offers higher output current (300mA vs ≤250mA), better thermal performance via SOT89-3L's exposed tab, and broader input range (2.7–5.5V vs 2.7–6.0V or 2.7–6.5V), making it optimal for thermally constrained, medium-current embedded systems.

FAQ
What is the minimum output capacitance required for stability with AP130-18YL-13?
A minimum 10µF ceramic capacitor must be placed between OUT and GND to ensure loop stability across all operating conditions. The datasheet specifies this value based on phase margin testing with 1µF input capacitance; using less than 10µF risks oscillation under load transients.
Can AP130-18YL-13 be used with input voltages below 2.7V?
No - the absolute minimum input voltage is 2.7V per the Recommended Operating Conditions table. Operation below this threshold may cause unregulated output or disable internal bandgap reference, resulting in unpredictable behavior or shutdown.
Does AP130-18YL-13 require an external bypass capacitor on the GND pin?
No external bypass capacitor is required on GND; however, the SOT89-3L package's pin 2 (GND) must be soldered to a ≥25mm² copper pour for effective thermal conduction. The GND connection serves as both electrical reference and primary heat path.
Is AP130-18YL-13 compatible with lead-free reflow profiles?
Yes - AP130-18YL-13 is RoHS-compliant and qualified for standard lead-free reflow (J-STD-020D Level 3, peak 260°C). The "L" suffix denotes lead-free finish, and the green molding compound meets halogen-free requirements (Br < 900ppm, Cl < 900ppm).
