Product details
Overview
AP130-25YRL-13 from Diodes Incorporated is a 300mA fixed-output 2.5V 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, thermal shutdown, and current-limit protection for battery-powered peripherals and embedded I/O rails.
For engineers reviewing the AP130-25YRL-13 datasheet, AP130-25YRL-13 pinout, AP130-25YRL-13 application, or AP130-25YRL-13 equivalent, key selection criteria include dropout voltage under 300mA load, thermal resistance (θJA = 100°C/W), output stability with 10µF ceramic capacitor, and RoHS-compliant green molding compound.
Technical Context
The AP130-25YRL-13 uses an internal PMOS pass transistor with 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current. Its bandgap reference and error amplifier deliver stable 2.5V output across –40°C to +85°C ambient temperature.
Protection circuitry includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered above +125°C junction temperature. PSRR reaches 58dB at 100Hz with 1µF input and 10µF output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±2% - ensures precise rail generation for 2.5V logic or analog circuitry |
| Max Output Current | 300mA - supports moderate-power microcontrollers, sensors, and interface ICs |
| Dropout Voltage | 400mV typ. at 300mA - enables operation down to 2.9V input for single-cell Li-ion or 3.3V rail derivation |
| Quiescent Current | 50µA typ. - minimizes standby power loss in always-on battery systems |
| Line Regulation | 0.1–0.3%/V - maintains tight output under varying input (e.g., decaying battery) |
| PSRR | 58dB at 100Hz - suppresses switching noise from upstream DC/DC converters |
| Thermal Resistance θJA | 100°C/W (SOT89-3L, no heatsink) - defines safe continuous power dissipation limit (~0.3W) |
Pinout & Package
SOT89-3L package: surface-mount, 3-pin, thermally enhanced plastic outline with exposed tab (pin 2 connected to GND for thermal conduction).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated Output | Delivers stable 2.5V; requires ≥10µF ceramic capacitor to ground for stability |
| 2 (GND) | Ground Reference & Thermal Pad | Common return path and primary thermal conduction path to PCB copper |
| 3 (IN) | Input Supply | Accepts 2.7–5.5V; must be bypassed with ≥1µF capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | 1.5Ω RON enables zero base-drive current and 50µA IQ independent of load |
| Fast Transient Response | Maintains <±20mV output deviation during 10–90% 300mA load steps due to high loop gain |
| Integrated Protection | Thermal shutdown + fold-back current limit prevent damage during overloads or shorts |
| Green Molding Compound | Halogen-free, RoHS-compliant package meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 |
Applications
| Battery-Powered IoT Sensor Node | USB Peripheral Power Rail |
|---|---|

IC Role / Device Role / Timing Role: Dedicated 2.5V rail for touch-sensing and display driver logic. Use Value: ±2% output accuracy guarantees consistent LED brightness and reliable capacitive button response. |
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 |
|---|---|---|---|
| MCP1700-2502E/TO | 250mA max output, 175mV dropout at 250mA, 1.8µA IQ | Limited to ultra-low-power sub-250mA loads; unsuitable for 300mA peak MCU bursts | Select when IQ <2µA is critical and load never exceeds 250mA |
| TPS73225DBVR | 250mA, 150mV dropout at 250mA, 400µA IQ, higher cost | Lower dropout but 8× higher quiescent current; better for high-efficiency mid-load apps | Choose when input headroom is <300mV and 400µA IQ is acceptable |
Compared with MCP1700-2502E/TO and TPS73225DBVR, the AP130-25YRL-13 uniquely balances 300mA capability, 400mV dropout, and 50µA IQ in a low-cost SOT89-3L package-ideal for cost-sensitive, battery-backed 2.5V systems needing robust thermal protection.

FAQ
What is the minimum input voltage required for AP130-25YRL-13 to maintain regulation at 300mA?
The AP130-25YRL-13 requires VIN ≥ VOUT + VDROP = 2.5V + 0.4V = 2.9V to sustain 300mA output while maintaining ±2% regulation. Below 2.9V, output voltage drops linearly with input; operation below 2.7V is outside recommended conditions per datasheet Section 4.
Can AP130-25YRL-13 be used with ceramic output capacitors only?
Yes-the AP130-25YRL-13 is stable with ≥10µF X5R/X7R ceramic capacitors on the output, as confirmed in the datasheet's Functional Descriptions section. No ESR requirements apply, unlike older LDOs, due to its internal compensation optimized for low-ESR ceramics.
Does the SOT89-3L package of AP130-25YRL-13 require a thermal pad connection to PCB ground?
Yes-pin 2 (GND) in the SOT89-3L package is electrically and thermally connected to the exposed metal tab. The datasheet specifies mounting on a minimum 1.40×1.60mm copper pad (typical 1.50mm) with thermal vias to inner layers for optimal θJA = 100°C/W performance.
Is AP130-25YRL-13 qualified for automotive applications?
No-AP130-25YRL-13 is specified for industrial temperature range (–40°C to +85°C ambient), not AEC-Q200. Diodes offers the AP7361 series for automotive-grade LDOs; this part lacks PPAP documentation, extended temperature validation, or automotive-specific qualification testing.
