Product details
Overview
AP130-33WG-7 from Diodes Incorporated is a 300mA fixed-output 3.3V 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 wireless modules and PC peripherals.
For engineers reviewing the AP130-33WG-7 datasheet, AP130-33WG-7 pinout, AP130-33WG-7 application, or AP130-33WG-7 equivalent, key selection criteria include dropout performance at 300mA, stability with 10µF output capacitance, thermal resistance (250°C/W), and SC59 lead-free green packaging compliance.
Technical Context
The AP130-33WG-7 uses an internal PMOS pass transistor 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) and line regulation (0.1%/V).
Protection circuitry includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered at TJ ≥ 125°C. The device requires a minimum 10µF ceramic output capacitor for stability across –40°C to +85°C ambient operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% - ensures stable core voltage for 3.3V logic and I/O interfaces |
| Max Output Current | 300mA - supports moderate-power microcontrollers and interface ICs |
| Dropout Voltage | 400mV @ 300mA - enables operation down to 3.7V input, suitable for single-cell Li-ion or 4xAA alkaline systems |
| Quiescent Current | 50µA typ - minimizes standby power loss in always-on battery applications |
| PSRR | 58dB @ 100Hz - suppresses ripple from noisy switching supplies feeding the LDO input |
| Thermal Resistance θJA | 250°C/W (SC59) - defines junction temperature rise under 300mA load on standard FR-4 PCB |
| Load Regulation | ±30mV (1–300mA) - maintains voltage stability during dynamic current steps in portable devices |
Pinout & Package
AP130-33WG-7 is housed in a lead-free, RoHS-compliant SC59 package (3-pin SOT-23 variant), measuring 2.90 × 1.30 × 1.00 mm with gull-wing leads. Thermal performance is optimized for single-sided 2oz copper FR-4 boards per Diodes Inc. AP02001 layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Power Supply | Accepts 2.7–5.5V DC; must be decoupled with ≥1µF capacitor near pin |
| 2 (OUT) | Regulated Output | Delivers stable 3.3V; requires ≥10µF low-ESR ceramic capacitor to ground for loop stability |
| 3 (GND) | Ground Reference | Common return path for input/output capacitors and load; connects directly to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | 1.5Ω RON enables zero gate-drive current, reducing system-level quiescent power |
| Fast Transient Response | Maintains <±1.5% VOUT deviation during 10–90% 200mA load steps due to high-gain error amplifier |
| Short-Circuit Fold-Back | Limits output current to 150–300mA during fault, reducing power dissipation and thermal stress |
| Green Molding Compound | Halogen-free (Br/Sb-free) epoxy meets IPC-4101D/21 requirements for environmentally sensitive designs |
| Thermal Shutdown | Activates at TJ ≥ 125°C and auto-recovers after cooldown, preventing permanent IC damage |

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-3302E/TT (Microchip) | 250mA max output, 175mV dropout @ 250mA, 1.6µA quiescent current | Lower IQ suits ultra-low-power sleep modes but lower current limits use in high-pulse loads | Select when standby current dominates design budget and peak load ≤250mA |
| TPS70633DBVR (TI) | 150mA max output, 210mV dropout @ 150mA, 4.5µA IQ, enable pin included | Enable control supports sequencing; insufficient current for 300mA loads like USB hubs | Choose when system-level power sequencing is required and load current stays below 150mA |
Compared with MCP1700T-3302E/TT and TPS70633DBVR, AP130-33WG-7 uniquely balances 300mA capability, 400mV dropout, and 50µA IQ in SC59 - making it optimal for space-constrained, medium-current battery systems where both runtime and peak load matter.

FAQ
What is the minimum output capacitance required for AP130-33WG-7 stability?
The AP130-33WG-7 requires a minimum 10µF ceramic capacitor with low ESR (≤100mΩ) between OUT and GND to ensure phase margin >45° and prevent oscillation. Aluminum or tantalum capacitors are not recommended due to higher ESR and potential instability.
Can AP130-33WG-7 operate with a 2.5V input?
No - the absolute minimum input voltage is 2.7V per datasheet specifications. At 2.5V input, the device cannot maintain regulated 3.3V output due to exceeding the dropout limit; operation below 2.7V risks unregulated output or shutdown.
Is AP130-33WG-7 compatible with lead-free reflow profiles?
Yes - AP130-33WG-7 uses lead-free terminations and green molding compound, qualified for JEDEC J-STD-020D-compliant reflow with peak temperature up to 260°C and time above liquidus of 60 seconds maximum.
Does AP130-33WG-7 include reverse polarity protection?
No - the device lacks internal reverse-voltage protection. Applying reversed input voltage may cause permanent damage. External series diode or MOSFET-based protection must be added if reverse input is possible in the system.
