Product details
Overview
AP130-20YG-13 from Diodes Incorporated is a fixed 2.0V output, 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 current limit and thermal shutdown protection, and is optimized for battery-powered devices requiring stable low-noise supply under light-to-moderate load.
For engineers reviewing the AP130-20YG-13 datasheet, AP130-20YG-13 pinout, AP130-20YG-13 application, or AP130-20YG-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θJA = 100°C/W), output voltage tolerance, PSRR (58dB @100Hz), and compatibility with 10µF minimum output capacitance for stability.
Technical Context
The AP130-20YG-13 uses a PMOS pass element with 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current (50µA typ). Its bandgap-referenced error amplifier ensures tight load regulation (±40mV over 1–300mA) and line regulation (±0.3%/V).
Internal protection includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered at TJ ≥ 125°C. The device operates across –40°C to +85°C ambient and supports input voltages from 2.7V to 5.5V - sufficient to regulate down from single-cell Li-ion or dual-cell alkaline sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% - enables direct powering of 2.0V logic rails without external feedback. |
| Max Output Current | 300mA continuous - supports moderate-power peripherals like USB PHYs or sensor interfaces. |
| Dropout Voltage | 400mV typ at 300mA - allows operation with only 2.4V input for 2.0V output, extending battery runtime. |
| Quiescent Current | 50µA typ at zero load - minimizes standby power loss in always-on battery systems. |
| PSRR | 58dB @100Hz - suppresses ripple from noisy switchers or shared input rails. |
| Thermal Resistance θJA | 100°C/W (SOT89-3L, no heatsink) - defines safe power dissipation limit: ≤300mW at ΔT = 30°C rise. |
| Protection Features | Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up or destruction during fault conditions. |
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: 4.50 × 2.90 × 1.50 mm (L×W×H), 1.5mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output node | Delivers stable 2.0V; requires ≥10µF ceramic or tantalum capacitor to ground for loop stability. |
| 2 (GND) | Ground reference and thermal pad | Primary return path and main thermal conduction path to PCB copper; must be soldered to ≥1cm² 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 transistor | Eliminates base current draw, enabling 50µA IQ independent of load - critical for battery longevity. |
| Fast transient response | Stabilizes within <10µs after 100mA load step - maintains voltage integrity for burst-mode digital loads. |
| Guaranteed 300mA output | Rated across full temperature and input range - eliminates derating calculations for industrial designs. |
| Green molding compound | Halogen-free (no Br/Sb), RoHS-compliant - meets IPC-1752A environmental compliance requirements. |
| Short-circuit fold-back | Limits peak fault current to ≤300mA and reduces it to ~150mA under hard short - lowers thermal stress during test or misuse. |
Applications
| Wireless Sensor Node | USB Peripheral Power |
|---|---|
|
Use Scenario: Sub-1W IoT sensor node powered by CR2032 or single Li-ion cell, operating intermittently with microamp sleep current. IC Role / Device Role / Timing Role: Primary 2.0V supply for MCU core and RF transceiver; regulates down from 3.0–4.2V battery range. Use Value: 50µA quiescent current extends shelf life >5 years; 400mV dropout enables usable runtime down to 2.4V battery voltage. |

IC Role / Device Role / Timing Role: Post-regulator filtering switcher ripple on VBUS-derived 3.3V/5V supply. Use Value: 58dB PSRR at 100Hz attenuates switching noise from upstream DC/DC converter, preventing data corruption. |
| Industrial Control I/O Module | Optical Drive Logic Supply |
|
Use Scenario: DIN-rail mounted PLC I/O module with isolated 2.0V logic for ADC drivers and level translators. IC Role / Device Role / Timing Role: Local point-of-load regulator for analog front-end circuitry requiring low-noise, stable bias.

Use Scenario: CD-ROM or DVD-ROM drive requiring dedicated 2.0V supply for servo control ASIC and laser driver interface. IC Role / Device Role / Timing Role: Low-noise, fast-response regulator for timing-critical servo loop electronics. Use Value: Fast transient response (<10µs) maintains voltage during sudden motor commutation spikes, preventing servo lock loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2002E/TO | 250mA max output, 175mV dropout at 250mA, 2µA IQ - lower current, much lower IQ, TO-92 package. | Best for ultra-low-power, low-current applications (e.g., RTC backup); unsuitable for 300mA loads. | Select if system load ≤250mA and standby IQ <5µA is mandatory; avoid for sustained 300mA operation. |
| TPS7A2020PDBVR | 300mA, 170mV dropout at 300mA, 25µA IQ, SOT-23-5 - lower dropout, smaller package, but requires external EN and BIAS pins. | Requires additional board space for enable control and bias supply; better for space-constrained, low-dropout designs. | Select when input-to-output margin is <300mV or PCB area is constrained; not drop-in due to pin count and bias requirement. |
Compared with MCP1700-2002E/TO and TPS7A2020PDBVR, the AP130-20YG-13 offers higher guaranteed output current (300mA) and simpler 3-pin integration in thermally robust SOT89-3L, making it optimal for cost-sensitive, medium-power industrial and optical applications where 400mV dropout is acceptable.

FAQ
What is the minimum output capacitance required for stability with AP130-20YG-13?
A minimum 10µF ceramic or tantalum capacitor must be placed between OUT and GND to ensure loop stability across all operating conditions. Lower values risk oscillation, especially under light loads. The datasheet specifies this as an absolute requirement - not a recommendation - due to internal compensation design.
Can AP130-20YG-13 operate with a 2.5V input while delivering 2.0V at 300mA?
Yes: with 2.5V input, the 400mV typical dropout leaves 2.1V output - within ±2% (1.96–2.04V) spec. However, worst-case dropout is 500mV, so output may dip to 2.0V at minimum input (2.5V) and maximum load/temperature. Design margin should verify worst-case VOUT ≥ 1.96V.
Is the exposed tab on the SOT89-3L package electrically connected?
No - the exposed thermal pad on AP130-20YG-13's SOT89-3L is internally connected to pin 2 (GND). It must be soldered to a GND copper pour for both electrical grounding and thermal dissipation; floating the pad degrades θJA by >30°C/W and risks thermal shutdown.
Does AP130-20YG-13 require an input bypass capacitor?
Yes: a 1µF ceramic capacitor is required between IN and GND, placed as close as possible to the device. This suppresses high-frequency noise and prevents instability caused by source impedance interacting with internal feedback. Omitting it may cause erratic behavior during load transients or EMI exposure.
