Product details
Overview
AP130-28YRG-13 from Diodes Incorporated is a fixed 2.8V, 300mA low-dropout linear regulator in SOT89R-3L package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates current limit, thermal shutdown, and short-circuit fold-back protection, and is optimized for battery-powered devices requiring stable low-noise voltage regulation.
For engineers reviewing the AP130-28YRG-13 datasheet, AP130-28YRG-13 pinout, AP130-28YRG-13 application, or AP130-28YRG-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θJA = 100°C/W), green RoHS-compliant packaging, and compatibility with 10µF output capacitance for stability.
Technical Context
The AP130-28YRG-13 uses a PMOS pass element with 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current (50µA typ). Its error amplifier and bandgap reference deliver tight load regulation (±30mV over 1–300mA) and line regulation (0.1%/V).
Internal protection circuitry includes fold-back current limiting (150–300mA short-circuit current) and thermal shutdown triggered above +125°C junction temperature. The device operates across –40°C to +85°C ambient with input range 2.7V–5.5V and requires ≥10µF ceramic output capacitor for stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% - ensures stable core logic supply for 2.8V I/O interfaces without external feedback. |
| Max Output Current | 300mA - supports moderate-power peripherals like USB PHYs or sensor signal chains. |
| Dropout Voltage | 400mV @ 300mA - enables operation down to 3.2V input, critical for single-cell Li-ion or 3.3V rail margining. |
| Quiescent Current | 50µA typ - minimizes standby power loss in always-on battery systems (e.g., IoT sensors). |
| PSRR | 58dB @ 100Hz - suppresses ripple from noisy switchers feeding the LDO input. |
| Thermal Resistance θJA | 100°C/W (SOT89R-3L, no heatsink) - defines max power dissipation (300mW) before thermal shutdown at +85°C ambient. |
| Protection Features | Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up or destruction during fault conditions. |
Pinout & Package
SOT89R-3L package: 3-pin, surface-mount, lead-free, green molding compound; exposed tab for thermal conduction (not electrically connected); footprint per Diodes AP02007.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: GND | Ground reference | Primary return path for load current and internal bias; must connect to low-impedance ground plane. |
| 2: IN | Input voltage supply | Accepts 2.7V–5.5V; requires ≥1µF bypass capacitor close to pin to suppress high-frequency noise. |
| 3: OUT | Regulated output | Delivers 2.8V ±2%; requires ≥10µF ceramic capacitor to ground for loop stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS pass transistor | RON = 1.5Ω enables 400mV dropout at 300mA while drawing zero gate drive current - reduces system standby power. |
| Fast transient response | Stabilizes within <10µs after 100mA load step - maintains voltage integrity for burst-mode digital loads. |
| Green RoHS-compliant package | SOT89R-3L with bromine/antimony-free molding compound - meets environmental compliance for industrial and consumer end markets. |
| Integrated protection | Thermal shutdown activates at TJ > +125°C; current limit folds back to ~150mA under short-circuit - eliminates need for external fault management. |
Applications
| Battery-Powered Wireless Sensors | USB Peripheral Power Management |
|---|---|
|
Use Scenario: Low-power Zigbee or BLE sensor node powered by CR2032 or single-cell Li-ion. IC Role / Device Role / Timing Role: Primary 2.8V supply for MCU, RF transceiver, and analog front-end. Use Value: 50µA quiescent current extends shelf life; 400mV dropout allows operation until battery reaches 3.2V. |
Use Scenario: USB 2.0 hub or card reader requiring clean 2.8V for PHY and controller logic. IC Role / Device Role / Timing Role: Post-regulator filtering noisy 3.3V VBUS-derived supply. Use Value: 58dB PSRR at 100Hz attenuates switching noise from upstream DC-DC converter. |
| Industrial Control I/O Modules | Optical Drive Logic Supply |
|
Use Scenario: DIN-rail mounted PLC I/O module with isolated 3.3V domain powering 2.8V level-shifted communication ICs. IC Role / Device Role / Timing Role: Local point-of-load regulator for RS-485 transceivers and GPIO expanders. Use Value: ±2% output accuracy ensures reliable logic thresholds; thermal shutdown protects against enclosure overheating. |
Use Scenario: CD-ROM or DVD-ROM drive mainboard supplying 2.8V to servo control ASIC and laser driver interface. IC Role / Device Role / Timing Role: Stable bias rail for precision analog circuits sensitive to supply ripple. Use Value: Good load regulation (±30mV) maintains timing margins during motor startup current surges. |
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-2802E/TT (Microchip) | 250mA rated, 175mV dropout @ 250mA, 2.5µA IQ - lower current, much lower quiescent current. | Best for ultra-low-power sub-250mA applications where IQ dominates battery life; not suitable for 300mA peak loads. | Select when standby current is critical and load never exceeds 250mA; verify thermal margin with θJA = 200°C/W (SOT23). |
| TPS73028DBVR (TI) | 200mA rated, 120mV dropout @ 200mA, 330µA IQ - lower dropout but higher IQ and lower current rating. | Preferred for low-noise, low-dropout needs in ≤200mA applications; less suitable for sustained 300mA loads or long battery life. | Choose for tighter dropout in space-constrained designs where 200mA suffices; confirm PSRR (60dB @ 100Hz) meets noise requirements. |
Compared with MCP1700T-2802E/TT and TPS73028DBVR, the AP130-28YRG-13 uniquely balances 300mA capability, 400mV dropout, and 50µA IQ in a thermally robust SOT89R-3L package - making it optimal for mid-current battery systems needing both runtime and reliability.

FAQ
What is the minimum output capacitance required for stability with AP130-28YRG-13?
The AP130-28YRG-13 requires a minimum 10µF ceramic capacitor from OUT to GND for guaranteed stability across all operating conditions. This value is specified in the Functional Descriptions section of DS31027 Rev. 8–2 and validated in typical performance curves. Using less capacitance may cause oscillation or poor transient response.
Can AP130-28YRG-13 be used with an input voltage below 2.7V?
No - the absolute minimum input voltage is 2.7V per Recommended Operating Conditions. Operation below this violates specification limits and risks unregulated output or failure to maintain 2.8V. At VIN = 2.7V, dropout margin is only 0V, so actual usable input starts at ≥3.2V for 300mA load.
Is the exposed pad on the SOT89R-3L package electrically connected?
No - the exposed thermal pad on the SOT89R-3L package is not electrically connected to any internal node. It serves only for thermal conduction to the PCB and must be soldered to a copper pour for effective heat dissipation, per Diodes' AP02007 land pattern recommendation.
Does AP130-28YRG-13 support reverse polarity protection?
No - the AP130-28YRG-13 lacks built-in reverse polarity protection. Applying reverse voltage to IN or OUT can damage the PMOS pass device. External protection (e.g., series Schottky diode or dedicated reverse-voltage IC) is required if system-level reverse input is possible.
