Product details
Overview
AP130-33YRG-13 from Diodes Incorporated is a fixed 3.3V, 300mA low-dropout linear regulator in SOT89R-3L package with 400mV dropout at full load, 50µA quiescent current, and ±2% output voltage accuracy-designed for battery-powered peripherals requiring stable low-noise supply under variable load.
For engineers reviewing the AP130-33YRG-13 datasheet, AP130-33YRG-13 pinout, AP130-33YRG-13 application, or AP130-33YRG-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θJA = 100°C/W), short-circuit fold-back protection, and green RoHS-compliant packaging for industrial and consumer PCB designs.
Technical Context
The AP130-33YRG-13 uses a PMOS pass element with internal 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current across load range. Its bandgap-referenced error amplifier delivers fast transient response and tight load regulation (±30mV from 1–300mA).
Integrated current-limit (450mA typ) and thermal shutdown circuitry provide fault protection without external components. The device requires only a 10µF output capacitor for stability and achieves 58dB PSRR at 100Hz with standard 1µF/10µF input/output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% - ensures compatibility with 3.3V logic rails and avoids external feedback network. |
| Max Output Current | 300mA continuous - supports USB peripherals, LAN cards, and wireless baseband ICs without derating. |
| Dropout Voltage | 400mV at 300mA - enables operation down to 3.7V input, suitable for single-cell Li-ion or three-cell NiMH systems. |
| Quiescent Current | 50µA typical - minimizes standby power loss in always-on battery applications like remote sensors. |
| PSRR | 58dB at 100Hz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Thermal Resistance θJA | 100°C/W (SOT89R-3L, no heatsink) - defines safe power dissipation limit of 330mW at 85°C ambient. |
| Protection Features | Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up and permanent damage during overload. |
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 for error amplifier and thermal shutdown comparator; must connect to low-impedance PCB ground plane. |
| 2 | IN | Input power supply node; requires ≥1µF ceramic bypass capacitor placed adjacent to pin to suppress high-frequency noise. |
| 3 | OUT | Regulated 3.3V output; requires ≥10µF low-ESR output capacitor for loop stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | RON = 1.5Ω eliminates base current draw, enabling true 50µA IQ independent of load. |
| Fast Transient Response | Stabilizes within 10µs after 100mA step load change-critical for burst-mode digital loads. |
| Load Regulation | ±30mV over 1–300mA load range-maintains 3.3V integrity across processor sleep/wake cycles. |
| Short-Circuit Fold-Back | Limits output current to 150–300mA during hard short, reducing power dissipation and junction temperature rise. |
| Green RoHS Compliance | No Br/Sb in molding compound; lead-free finish meets EU Directive 2002/95/EC exemptions. |
Applications
| Wireless Communication Modules | CD/DVD-ROM Drive Logic |

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-3.3TRG1 | Higher IQ (80µA), lower max current (150mA), SOT23-5 package with enable pin. | Lacks thermal shutdown; suited for space-constrained, low-power logic rails-not high-current peripherals. | Select when board area is critical and load never exceeds 150mA; verify enable logic compatibility. |
| MCP1700T-3302E/TT | Lower IQ (1.6µA), same 300mA rating, but higher dropout (600mV @ 250mA) and no short-circuit fold-back. | Optimized for ultra-low-power sensor nodes; unsuitable for burst-load applications requiring fast recovery. | Prefer for energy-harvesting or coin-cell designs where dropout margin >600mV is acceptable. |
Compared with AP2202K-3.3TRG1 and MCP1700T-3302E/TT, the AP130-33YRG-13 uniquely balances 300mA capability, 400mV dropout, integrated fold-back protection, and 100°C/W thermal performance in a cost-effective SOT89R-3L package-making it optimal for mid-power battery peripherals where reliability under transient overload is essential.

FAQ
What is the minimum input voltage required for AP130-33YRG-13 to maintain regulation at 300mA?
The minimum input voltage is 3.7V, calculated as VOUT + VDROP = 3.3V + 0.4V. Below this, output voltage drops out of regulation. The device operates down to 2.7V input but cannot sustain 300mA below 3.7V due to dropout limitation.
Can AP130-33YRG-13 be used without an output capacitor?
No. A minimum 10µF low-ESR output capacitor is mandatory for stability, as confirmed in the Functional Descriptions section. Omitting it causes oscillation and potential damage; ceramic or tantalum types meeting ESR specifications must be used.
Does AP130-33YRG-13 require a specific PCB pad layout for thermal performance?
Yes. The SOT89R-3L package requires the land pattern specified in Diodes' AP02007 document: 4.5mm × 3.0mm copper pad with thermal vias to inner layers. Deviating reduces θJA performance and risks thermal shutdown under sustained 300mA load.
Is AP130-33YRG-13 qualified for automotive applications?
No. It is rated for industrial temperature range (−40°C to +85°C ambient), not AEC-Q100. Diodes does not list this variant in automotive-grade product lines; use AP7361 or AP7363 series for automotive-qualified 3.3V LDOs.
