Product details
Overview
AP130-28YRL-13 from Diodes Incorporated is a fixed 2.8V, 300mA low-dropout linear regulator in SOT89-3L package, featuring 400mV dropout at full load, ±2% output voltage 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 AP130-28YRL-13 datasheet, AP130-28YRL-13 pinout, AP130-28YRL-13 application, or AP130-28YRL-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θJA = 100°C/W), output stability with 10µF ceramic output capacitor, and compatibility with 2.7–5.5V input rails in portable peripheral designs.
Technical Context
The AP130-28YRL-13 employs a PMOS pass transistor with internal 1.5Ω RON, enabling low quiescent current and eliminating base drive requirements. Its error amplifier uses a bandgap reference to regulate output against line (0.1–0.3%/V) and load (30–40mV) variations.
Protection circuitry includes thermal shutdown triggered at ~125°C junction temperature and current limit set at 350–450mA with fold-back behavior below 1.05V output. PSRR reaches 58dB at 100Hz with 1µF input and 10µF output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% - ensures stable core voltage for 2.8V I/O interfaces without external feedback. |
| Max Output Current | 300mA continuous - supports moderate-power peripherals like USB transceivers or sensor hubs. |
| Dropout Voltage | 400mV typ. at 300mA - enables operation down to 3.2V input while maintaining regulation. |
| Quiescent Current | 50µA typ. at zero load - extends battery life in always-on standby modes. |
| PSRR | 58dB at 100Hz - suppresses ripple from noisy DC-DC converters feeding the LDO input. |
| Thermal Resistance θJA | 100°C/W (SOT89-3L, no heatsink) - defines maximum power dissipation (300mW) before thermal shutdown. |
| Line Regulation | 0.1–0.3%/V - minimizes output drift across 2.7–5.5V input range. |
Pinout & Package
SOT89-3L package: 3-pin surface-mount, thermally enhanced plastic case with exposed tab (pin 2) tied to GND for improved heat dissipation. Dimensions: 4.50mm × 2.48mm × 1.50mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output node | Delivers stable 2.8V to load; requires ≥10µF ceramic capacitor to ground for stability. |
| 2 (GND) | Ground reference and thermal pad | Primary return path and thermal conduction path; must be soldered to large copper pour. |
| 3 (IN) | Unregulated input supply | Accepts 2.7–5.5V; requires local 1µF bypass capacitor near pin to suppress high-frequency noise. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS pass element | Eliminates base current draw and enables ultra-low IQ (50µA), critical for battery longevity. |
| Integrated thermal shutdown | Activates at ~125°C junction temperature, preventing permanent damage during sustained overload. |
| Fold-back current limiting | Reduces short-circuit current to 150–300mA when VOUT < 1.05V, lowering power dissipation during fault. |
| ±2% output accuracy | Guarantees compliance with 2.8V I/O voltage tolerance of microcontrollers and logic devices. |
| Lead-free & RoHS-compliant | Meets EU Directive 2002/95/EC with green molding compound (no Br/Sb), suitable for eco-sensitive designs. |
Applications

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-2.8TRG1 | Higher IQ (80µA), lower max current (150mA), same SOT23-3 package | Not suitable for 300mA loads; better for ultra-low-power sub-100mA nodes | Select if board space is constrained and load current ≤150mA. |
| MCP1700T-2802E/TT | Lower IQ (1.6µA), same 2.8V output, but only 250mA rated; SOT23-3 | Limited peak current capability; less robust under transient overload | Choose only for micropower applications where 250mA is sufficient and thermal margin is ample. |
Compared with AP130-28YRL-13, AP2202K-2.8TRG1 trades current capacity for smaller footprint, while MCP1700T-2802E/TT offers micropower advantage at cost of reduced current headroom and thermal resilience-neither matches the 300mA/100°C/W combination in SOT89-3L.

FAQ
What is the minimum input voltage required for AP130-28YRL-13 to maintain regulation at 300mA?
The minimum input voltage is calculated as VOUT + VDROP = 2.8V + 0.4V = 3.2V. At 300mA load and 25°C, the typical dropout is 400mV; the datasheet specifies 500mV maximum, so 3.3V input ensures regulation across temperature and process variation. Below 3.2V, output voltage will sag proportionally.
Can AP130-28YRL-13 operate with a 1µF ceramic input capacitor and no bulk electrolytic?
Yes-the datasheet specifies CIN = 1µF as sufficient for stability and transient response. A bulk electrolytic is not required unless the upstream source has high impedance or long trace inductance. The 1µF X7R ceramic placed within 2mm of the IN pin meets all recommended operating conditions.
Is the exposed thermal pad on the SOT89-3L package electrically connected internally?
No-the exposed pad (pin 2) is internally connected only to GND. It is not isolated or floating. PCB layout must connect it directly to a solid GND plane using multiple thermal vias to achieve the specified θJA = 100°C/W; leaving it unconnected degrades thermal performance by >40%.
Does AP130-28YRL-13 require an output capacitor, and what type is recommended?
Yes-a minimum 10µF ceramic capacitor (X5R or X7R) is mandatory between OUT and GND for stability, per functional description on page 6. Tantalum or aluminum electrolytic capacitors are not recommended due to ESR and aging effects; ceramic ensures consistent phase margin and fast transient recovery.
