Product details
Overview
AP130-20YRL-13 from Diodes Incorporated is a fixed 2.0V, 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 thermal shutdown, current limit with fold-back, and operates across 2.7V–5.5V input range. Designed for battery-powered peripherals including PC cards and wireless modules.
For engineers reviewing the AP130-20YRL-13 datasheet, AP130-20YRL-13 pinout, AP130-20YRL-13 application, or AP130-20YRL-13 equivalent, key selection criteria include dropout performance under 300mA load, 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 element with 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current (50µA typ). Its error amplifier uses a 1.08V bandgap reference to regulate output within ±2% over temperature and line/load variations.
Protection circuitry includes thermal shutdown triggered above +125°C junction temperature and current limiting that folds back short-circuit current to 150–300mA - reducing power dissipation during fault conditions without latch-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% at 1mA load - ensures stable core voltage for 2.0V logic rails |
| Max Output Current | 300mA continuous - supports moderate-power peripherals like LAN PHYs or USB transceivers |
| Dropout Voltage | 400mV typ at 300mA - enables operation down to 2.4V input while maintaining regulation |
| Quiescent Current | 50µA typ at zero load - minimizes standby power loss in battery-backed systems |
| PSRR | 58dB at 100Hz - suppresses ripple from noisy switcher outputs feeding the LDO input |
| Thermal Resistance θJA | 100°C/W (SOT89-3L, no heatsink) - defines safe power dissipation limit of 330mW at 85°C ambient |
| Line Regulation | 0.1–0.3%/V - maintains tight output stability across full 2.7–5.5V input range |
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: 4.50mm × 2.48mm × 1.50mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output node | Delivers fixed 2.0V to load; requires ≥10µF ceramic capacitor to ground for stability |
| 2 (GND) | Ground reference and thermal pad | Primary return path and main thermal conduction path to PCB copper; must be soldered to large copper area |
| 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 transistor | 1.5Ω RON eliminates gate drive current, enabling 50µA IQ independent of load |
| Current-limit fold-back | Reduces short-circuit current to 150–300mA, limiting fault power dissipation and preventing thermal runaway |
| Thermal shutdown | Activates at TJ > +125°C and auto-recovers after cooldown - protects against sustained overload |
| Green RoHS-compliant packaging | SOT89-3L with halogen-free molding compound (no Br/Sb) and lead-free finish per EU Directive 2002/95/EC |

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-2.0TRG1 | 200mA rated, 350mV dropout at 200mA, SOT23-5 package with enable pin | Lacks thermal shutdown; requires external EN control for sequencing | Select when lower cost and enable functionality outweigh need for 300mA rating and integrated protection |
| MCP1700T-2002E/TT | 250mA rated, 1.6µA IQ, SOT23-3, but only 4% output accuracy and no fold-back current limit | No thermal shutdown; higher output tolerance impacts timing-critical logic | Prefer for ultra-low-power sensor nodes where 250mA suffices and 4% VOUT error is acceptable |
Compared with AP2202K-2.0TRG1 and MCP1700T-2002E/TT, the AP130-20YRL-13 delivers higher output current (300mA vs. ≤250mA), tighter accuracy (±2% vs. ±4%), and comprehensive protection (fold-back + thermal shutdown), making it optimal for industrial peripherals requiring robustness and margin.

FAQ
What is the minimum input voltage required for AP130-20YRL-13 to maintain 2.0V output at 300mA?
The minimum input voltage is calculated as VOUT + VDROP = 2.0V + 0.4V = 2.4V. At 300mA load and 25°C, the typical dropout is 400mV; worst-case is 500mV per datasheet, so 2.5V ensures regulation across temperature and process variation. Operation below 2.7V input is not recommended per absolute maximum ratings.
Can AP130-20YRL-13 be used with ceramic output capacitors?
Yes - the AP130 is stable with 10µF ceramic output capacitors (X5R/X7R), as confirmed in the datasheet's Functional Descriptions section. Unlike some older LDOs, it does not require ESR-based damping; the internal compensation is optimized for low-ESR ceramics, simplifying layout and reducing board space.
Does AP130-20YRL-13 include reverse polarity or reverse current protection?
No - the AP130-20YRL-13 lacks reverse polarity or reverse current protection. The PMOS pass device inherently blocks reverse current flow from OUT to IN, but it offers no protection against inverted input voltage. External diode or MOSFET-based protection must be added if reverse input is possible in the system.
How does the thermal shutdown behavior recover after activation?
Thermal shutdown is non-latching: once junction temperature falls below the hysteresis threshold (~15°C below trip point), the device automatically resumes normal regulation without requiring power cycle or external reset. Recovery time depends on PCB thermal mass and ambient cooling, typically within seconds under natural convection.
