Product details
Overview
AP130-33WL-7 from Diodes Incorporated is a fixed 3.3V, 300mA low-dropout linear regulator in SC59 package with 400mV dropout at full load, 50µA quiescent current, and ±2% output voltage accuracy-designed for battery-powered wireless communication modules requiring stable low-noise supply under light-to-moderate load.
For engineers reviewing the AP130-33WL-7 datasheet, AP130-33WL-7 pinout, AP130-33WL-7 application, or AP130-33WL-7 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (250°C/W for SC59), PSRR (58dB @100Hz), short-circuit fold-back protection, and RoHS-compliant lead-free packaging.
Technical Context
The AP130-33WL-7 uses a PMOS pass element with internal 1.5Ω RON, eliminating base drive current and enabling ultra-low quiescent current (50µA typical). Its error amplifier and bandgap reference deliver tight load regulation (±40mV over 1–300mA) and line regulation (0.3%/V).
Integrated current-limit (450mA typ) and thermal shutdown with fold-back short-circuit protection ensure robust operation during fault conditions. The device requires only 10µF output capacitance for stability and achieves 58dB power supply ripple rejection at 100Hz with standard 1µF/10µF input/output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% - ensures compatibility with 3.3V logic and interface ICs without external feedback. |
| Max Output Current | 300mA continuous - supports moderate-power microcontrollers, RF transceivers, and peripheral ICs. |
| Dropout Voltage | 400mV @ 300mA - enables operation down to 3.7V input, suitable for single-cell Li-ion or dual-cell alkaline systems. |
| Quiescent Current | 50µA @ no load - minimizes standby power loss in always-on battery applications. |
| PSRR | 58dB @ 100Hz - suppresses switching noise from upstream DC/DC converters feeding the LDO. |
| Thermal Resistance θJA | 250°C/W (SC59) - defines maximum power dissipation (≈360mW at 85°C ambient) before thermal shutdown. |
| Protection Features | Current limit + thermal shutdown + short-circuit fold-back - prevents latch-up and permanent damage during overload. |
Pinout & Package
AP130-33WL-7 is housed in the SC59 surface-mount package (2.90 × 1.30 × 0.95 mm), optimized for space-constrained portable designs. It features gull-wing leads and RoHS-compliant matte-tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Power Supply | Accepts 2.7–5.5V; must be decoupled with ≥1µF ceramic capacitor close to pin. |
| 2 (OUT) | Regulated Output | Delivers stable 3.3V; requires ≥10µF low-ESR output capacitor for loop stability. |
| 3 (GND) | Analog/Digital Ground Reference | Common return path for input, output, and internal circuitry; must connect to low-impedance ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | RON = 1.5Ω eliminates base current draw, enabling true 50µA IQ across full load range. |
| Fast Transient Response | Stabilizes within <10µs after 100mA step load change - critical for burst-mode RF ICs. |
| Load Regulation | ±40mV over 1–300mA - maintains 3.3V integrity across dynamic processor or transceiver loads. |
| Green Molding Compound | Halogen-free (no Br/Sb) - meets IPC-1752A environmental compliance for industrial and consumer products. |
| Short-Circuit Fold-Back | Limits output current to ~150mA during hard short - reduces junction temperature rise and enables safe recovery. |
Applications
| Wireless Communication Module | Battery-Powered Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3302E/TT (Microchip) | 250mA max output, 175mV dropout @ 250mA, 1.6µA IQ - lower current, much lower IQ, higher cost. | Suitable only for sub-250mA loads; insufficient for 300mA peak demands of RF transceivers. | Select if ultra-low standby power dominates over output current capability. |
| TPS73033DBVR (TI) | 200mA max output, 120mV dropout @ 200mA, 330µA IQ - lower dropout but higher IQ and lower current rating. | Cannot sustain 300mA continuous load; thermal derating required above 150mA in SC59. | Prefer only when input headroom is severely constrained (<150mV) and load current ≤200mA. |
Compared with MCP1700T-3302E/TT and TPS73033DBVR, AP130-33WL-7 uniquely balances 300mA delivery, 400mV dropout, and 50µA IQ in a cost-effective SC59 package-making it optimal for mid-current, battery-sensitive applications where both peak load and standby efficiency matter.

FAQ
What is the minimum input voltage required for AP130-33WL-7 to maintain regulation at 300mA?
The AP130-33WL-7 requires VIN ≥ VOUT + VDROP = 3.3V + 0.4V = 3.7V to sustain 300mA output while maintaining ±2% regulation. Below 3.7V, output voltage drops linearly with input; operation below 2.7V is outside absolute maximum ratings and not functional.
Can AP130-33WL-7 be used with ceramic output capacitors?
Yes - the AP130-33WL-7 is stable with ceramic capacitors ≥10µF and ESR ≥10mΩ. Unlike some older LDOs, it does not require tantalum or aluminum electrolytic types; X5R/X7R ceramics are fully compatible and recommended for size and reliability.
Does AP130-33WL-7 have reverse polarity or reverse current protection?
No - the AP130-33WL-7 lacks internal reverse-voltage or reverse-current blocking. If input can fall below output (e.g., during hot-swap or battery removal), an external Schottky diode between IN and OUT is required to prevent backfeed and potential damage.
How does thermal shutdown behave during sustained overload?
Under continuous overload, AP130-33WL-7 activates thermal shutdown at TJ ≈ 150°C, disabling output until junction cools by ~20°C. Hysteresis prevents rapid cycling; recovery time depends on PCB copper area and ambient airflow - typical cooldown is 100–300ms on standard 2oz FR-4.
