Product details
Overview
AP130-20YL-13 from Diodes Incorporated is a fixed 2.0V, 300mA low-dropout linear regulator in SOT89-3L package, featuring 400mV dropout at full load, 50µA quiescent current, and ±2% output voltage accuracy. It integrates PMOS pass element, thermal shutdown, and current-limit protection for battery-powered peripherals and embedded I/O rails.
For engineers reviewing the AP130-20YL-13 datasheet, AP130-20YL-13 pinout, AP130-20YL-13 application, or AP130-20YL-13 equivalent, key selection criteria include dropout performance at 300mA, stability with 10µF output capacitance, thermal resistance (θJA = 100°C/W), and compatibility with 2.7–5.5V input sources in space-constrained designs.
Technical Context
The AP130-20YL-13 employs a PMOS pass transistor with 1.5Ω on-resistance, eliminating base drive current and enabling ultra-low quiescent current across load range. Its error amplifier uses a 1.08V internal reference and bandgap circuitry to maintain regulation under varying line and load conditions.
Protection functions are implemented via dedicated current-limit circuitry (350–450mA trip) and thermal shutdown with fold-back short-circuit current limiting (150–300mA). The device requires ≥10µF ceramic or tantalum output capacitance for stability and exhibits 58dB PSRR at 100Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% - ensures stable core voltage for 2.0V logic interfaces and low-power microcontrollers. |
| Max Output Current | 300mA - supports moderate-power peripherals such as USB PHYs, sensor signal chains, and memory I/O buffers. |
| Dropout Voltage | 400mV @ 300mA - enables operation from 2.4V input (e.g., single LiFePO₄ cell or regulated 2.7V rail). |
| Quiescent Current | 50µA typical - minimizes standby power loss in always-on battery-backed systems. |
| Line Regulation | 0.1–0.3%/V - maintains tight output tolerance despite input ripple or battery discharge slope. |
| PSRR | 58dB @ 100Hz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Thermal Resistance θJA | 100°C/W (SOT89-3L) - defines maximum power dissipation (300mW) before thermal shutdown at 85°C ambient. |
Pinout & Package
SOT89-3L package: 3-pin surface-mount, thermally enhanced leadframe with exposed tab (pin 2 connected to GND). Dimensions: 4.5mm × 2.5mm × 1.5mm, 1.5mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated Output | Delivers stable 2.0V to load; requires ≥10µF capacitor to ground for loop stability. |
| 2 (GND) | Ground Reference & Thermal Pad | Primary return path and main thermal conduction path to PCB copper; must be soldered to ≥100mm² copper pour. |
| 3 (IN) | Input Supply | Accepts 2.7–5.5V unregulated input; minimum headroom of 400mV required for regulation at 300mA. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | RON = 1.5Ω eliminates base current draw, enabling constant 50µA IQ from zero to full load. |
| Fast Transient Response | Stabilizes within 10µs after 100mA step load change due to high-gain error amplifier and optimized compensation. |
| Integrated Protection | Current limit (350–450mA) + thermal shutdown + short-circuit fold-back prevent latch-up or permanent damage during fault events. |
| Green & RoHS Compliance | Lead-free finish and halogen-free molding compound meet EU Directive 2002/95/EC and JEDEC J-STD-020 reflow profiles. |
Applications
| Battery-Powered IoT Sensor Node | USB Peripheral Power Rail |
|---|---|

| Industrial PLC I/O Module | Embedded Display Backlight Driver Bias |
Use Scenario: DIN-rail mounted PLC module with isolated 24V input and multiple 2.0V digital I/O channels. IC Role / Device Role / Timing Role: Local point-of-load regulator for FPGA I/O banks and level-shifting transceivers interfacing to field sensors. Use Value: 300mA output supports up to eight 25mA GPIOs; thermal shutdown prevents failure during sustained overcurrent faults. | Use Scenario: Small-form-factor medical display using white LED backlight with integrated 2.0V logic control interface. IC Role / Device Role / Timing Role: Dedicated 2.0V supply for LED driver IC's digital control logic and EEPROM configuration storage. Use Value: Load regulation ≤40mV ensures stable I²C communication timing across 1–300mA load range; SC59R-compatible footprint allows layout reuse. |
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 |
|---|---|---|---|
| MCP1700T-2002E/TT (Microchip) | 250mA max output, 175mV dropout @ 250mA, 1.6µA IQ - lower power but lower current capability. | Optimized for micropower <100µA systems; insufficient for 300mA continuous loads. | Select when standby current dominates design priority and peak load ≤250mA. |
| TPS73020DBVR (TI) | 200mA max output, 120mV dropout @ 200mA, 330µA IQ - tighter accuracy (±1%) but higher quiescent current. | Targets precision analog rails where noise and accuracy outweigh efficiency. | Select when ±1% tolerance and sub-200mV dropout are mandatory, and 200mA suffices. |
Compared with MCP1700T-2002E/TT and TPS73020DBVR, the AP130-20YL-13 uniquely balances 300mA delivery, 400mV dropout, and 50µA IQ in a thermally robust SOT89-3L package-making it optimal for mid-power, battery-sensitive applications where both current and quiescent performance matter.

FAQ
What is the minimum input voltage required for regulation at 300mA output?
The AP130-20YL-13 requires a minimum input voltage of 2.4V to maintain 2.0V output regulation at 300mA, based on its 400mV typical dropout voltage. Below this threshold, output voltage drops linearly with input; operation below 2.7V is outside recommended conditions per datasheet Section 4.
Can AP130-20YL-13 be used with ceramic output capacitors?
Yes - the AP130-20YL-13 is stable with ceramic capacitors ≥10µF and ESR ≥10mΩ. The datasheet specifies 10µF tantalum or ceramic as minimum; no series resistor is needed, unlike older LDOs requiring ESR-based compensation.
Is thermal pad (pin 2) electrically connected to GND?
Yes - in the SOT89-3L package, pin 2 is the GND terminal and also serves as the thermal pad. It must be soldered directly to a PCB ground plane for both electrical functionality and thermal performance; floating or insulated connection degrades θJA and risks thermal shutdown.
Does AP130-20YL-13 support reverse polarity protection?
No - the AP130-20YL-13 lacks built-in reverse-voltage protection. Applying reverse polarity to IN or OUT can cause latch-up or permanent damage. External protection (e.g., series Schottky diode or MOSFET-based ideal diode) is required in systems with potential reverse-battery or hot-swap conditions.
