Product details
Overview
AP130-20WG-7 from Diodes Incorporated is a fixed 2.0V output, 300mA low-dropout linear regulator in SC59 package with 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 AP130-20WG-7 datasheet, AP130-20WG-7 pinout, AP130-20WG-7 application, or AP130-20WG-7 equivalent, key selection criteria include dropout performance at 300mA, stability with 10µF output capacitance, SC59 footprint compatibility, and thermal resistance of 250°C/W in standard PCB layout.
Technical Context
The AP130-20WG-7 uses a PMOS pass transistor with 1.5Ω on-resistance and no base drive current, enabling ultra-low quiescent current (50µA typ) across 0–300mA load. Its error amplifier and bandgap reference deliver tight 2.0V regulation (±2%) over -40°C to +85°C ambient.
Internal current fold-back and thermal shutdown activate under short-circuit or overload conditions. PSRR reaches 58dB at 100Hz with 1µF input and 10µF output capacitors, supporting noise-sensitive analog and RF subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% - ensures stable core voltage for 2.0V logic or analog biasing without external feedback. |
| Max Output Current | 300mA - supports moderate-power microcontrollers, sensors, or interface ICs without derating at TA ≤ 85°C. |
| Dropout Voltage | 400mV @ 300mA - enables operation down to VIN = 2.4V while maintaining regulated 2.0V output. |
| Quiescent Current | 50µA typ - minimizes standby power loss in always-on battery applications like remote controls or IoT endpoints. |
| Load Regulation | 30–40mV over 1–300mA - maintains output stability during dynamic load steps typical in digital I/O switching. |
| PSRR | 58dB @ 100Hz - suppresses ripple from noisy DC-DC converters feeding the LDO input. |
| Thermal Resistance θJA | 250°C/W (SC59) - requires minimal copper area for thermal management in space-constrained consumer PCBs. |
Pinout & Package
AP130-20WG-7 is housed in a lead-free, RoHS-compliant SC59 package (3-pin, SOT-23 compatible outline), measuring 2.90 × 1.30 × 1.00 mm with gull-wing leads. Thermal performance assumes FR-4 board with single-sided 2oz copper and minimum recommended pad layout per AP02001.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Power Supply | Accepts 2.7–5.5V input; requires ≥1µF ceramic capacitor to ground for stability and transient response. |
| 2 (OUT) | Regulated Output | Delivers fixed 2.0V ±2%; must be decoupled with ≥10µF low-ESR capacitor to ensure loop stability. |
| 3 (GND) | Analog Ground Reference | Low-impedance return path for error amplifier and bandgap; must connect directly to power ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | RON = 1.5Ω with zero gate drive current - eliminates base current loss, enabling true 50µA IQ across full load range. |
| Fast Transient Response | Stable with 10µF output cap - recovers within microseconds from 100mA load steps, critical for burst-mode processors. |
| Short-Circuit Fold-Back | Limits output current to 150–300mA during fault - reduces power dissipation and prevents thermal runaway. |
| Green Molding Compound | Halogen-free (no Br/Sb) - meets IPC-4101D/21 and JEDEC J-STD-020 reflow compliance for eco-conscious manufacturing. |
| Thermal Shutdown | Activates at TJ ≈ 125°C - protects die integrity during sustained overload or poor heatsinking in sealed enclosures. |
Applications
| Wireless Sensor Node | USB Peripheral Controller |
|---|---|
|

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 | Higher IQ (80µA typ), same 300mA rating, SOT-23-5 package with enable pin. | Requires enable control logic; better suited for systems needing dynamic LDO sequencing. | Select if system requires active enable/disable and can accommodate 5-pin footprint. |
| MCP1700T-2002E/TT | Lower IQ (1.6µA), lower current (250mA), SOT-23-3 package, tighter initial accuracy (±0.4%). | Optimized for ultra-low-power wake-on-event designs; not rated for 300mA continuous loads. | Select only for sub-250mA applications where nanoampere standby dominates power budget. |
Compared with AP2202K-2.0TRG1 and MCP1700T-2002E/TT, the AP130-20WG-7 uniquely balances 300mA capability, 50µA IQ, and SC59 footprint-making it optimal for cost-sensitive, space-constrained 2.0V rails where enable functionality is unnecessary and load exceeds 250mA.

FAQ
What is the minimum input voltage required for AP130-20WG-7 to maintain regulation at 300mA?
The AP130-20WG-7 requires VIN ≥ VOUT + VDROP = 2.0V + 0.4V = 2.4V to sustain regulation at 300mA load. Below 2.4V, output voltage drops linearly with input; datasheet specifies guaranteed operation from 2.7V to 5.5V for full specification compliance.
Can AP130-20WG-7 be used with ceramic output capacitors?
Yes - the AP130-20WG-7 is stable with ceramic output capacitors ≥10µF and ESR ≥10mΩ. The datasheet explicitly recommends low-ESR ceramics and confirms stability under load transients when using 10µF X5R/X7R types, eliminating need for tantalum or aluminum electrolytic.
Does AP130-20WG-7 require an input capacitor?
Yes - a minimum 1µF ceramic capacitor is required between IN and GND. This capacitor reduces input impedance, suppresses high-frequency noise from upstream sources, and prevents oscillation during fast load transients; placement within 5mm of the IN pin is critical for performance.
Is AP130-20WG-7 qualified for automotive applications?
No - AP130-20WG-7 is specified for industrial and commercial temperature ranges (-40°C to +85°C ambient), not AEC-Q100. It lacks automotive qualification, extended temperature grade (−40°C to +125°C junction), or PPAP documentation; Diodes' AP73xx series is recommended for automotive-grade LDOs.
