Product details

Overview

AP130-30WG-7 from Diodes Incorporated is a 300mA fixed-output 3.0V low-dropout linear regulator in SC59 package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates PMOS pass element with no base current draw, thermal shutdown, and fold-back short-circuit protection-designed for battery-powered wireless modules requiring stable low-noise 3.0V rail.

For engineers reviewing the AP130-30WG-7 datasheet, AP130-30WG-7 pinout, AP130-30WG-7 application, or AP130-30WG-7 equivalent, key selection criteria include dropout voltage under 300mA load, thermal resistance (250°C/W for SC59), output voltage tolerance, PSRR at 100Hz (58dB), and compatibility with 1µF input / 10µF output capacitor network.

Technical Context

The AP130-30WG-7 uses a PMOS pass transistor with internal 1.5Ω R_ON, enabling ultra-low quiescent current and eliminating base drive requirements. Its bandgap-referenced error amplifier delivers fast transient response and tight load regulation (±40mV over 1–300mA).

Protection circuitry includes fold-back current limiting (150–300mA short-circuit current) and thermal shutdown triggered at junction temperatures exceeding +125°C. The device operates across –40°C to +85°C ambient with input range 2.7V–5.5V and requires ≥10µF output capacitance for stability.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0V ±2% - ensures stable logic supply for 3.3V-tolerant I/O interfaces without external feedback.
Dropout Voltage	400mV typ. at 300mA - enables operation down to 3.4V input while maintaining regulated 3.0V output.
Quiescent Current	50µA typ. at zero load - minimizes standby power loss in always-on battery systems.
PSRR	58dB at 100Hz - suppresses ripple from noisy DC-DC pre-regulators feeding the LDO input.
Thermal Resistance θ_JA	250°C/W (SC59) - limits max junction temperature to 125°C at 300mA with 25°C ambient and minimal PCB copper.
Current Limit	350–450mA - provides fold-back protection during sustained overload without latch-up.
Line Regulation	0.1–0.3%/V - maintains output stability despite input variations from battery discharge.

Pinout & Package

AP130-30WG-7 is housed in SC59 package (JEDEC TO-236AB), a 3-pin surface-mount plastic package with 2.7mm × 2.9mm footprint and 1.0mm height. Pin 1 = IN, Pin 2 = OUT, Pin 3 = GND (top view, left-to-right).

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Power Input	Accepts 2.7–5.5V unregulated input; requires ≥1µF ceramic decoupling close to pin.
2 (OUT)	Regulated Output	Delivers fixed 3.0V ±2%; requires ≥10µF low-ESR output capacitor for loop stability.
3 (GND)	Ground Reference	Common return path for error amplifier, bandgap, and pass transistor; must connect to low-impedance ground plane.

Key Features

Feature	Design Value
PMOS Pass Element	RON = 1.5Ω with zero gate drive current - eliminates base current loss and improves light-load efficiency.
Fast Transient Response	Stabilizes within <10µs after 100mA step load change - supports burst-mode digital loads like RF transceivers.
Thermal Shutdown	Activates at TJ > +125°C with automatic recovery - prevents permanent damage during sustained overload or poor heatsinking.
Fold-Back Current Limit	Reduces short-circuit current to 150–300mA - limits power dissipation and avoids thermal runaway during output fault.
Green Molding Compound	Halogen-free, RoHS-compliant (Br/Sb free) - meets IPC-1752A material declaration requirements for industrial end equipment.

Applications

Use Value: Low output noise prevents visible flicker in analog video paths; SC59 package fits tight board space near display connector.

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-3.0TRG1	Higher IQ (80µA), SOT-23-5 package, integrated enable pin - adds control flexibility but increases footprint.	Requires external enable signal routing; better suited for power-sequenced multi-rail systems.	Select when system-level power management demands active enable/disable capability.
MCP1700T-3002E/TT	Lower IQ (1.6µA), SOT-23-3 package, 250mA rating - optimized for ultra-low-power sleep modes but derated for continuous 300mA.	Limited to intermittent 300mA bursts; not rated for sustained 300mA at elevated temperature.	Select only for duty-cycled applications where average current <100mA and peak duration <10ms.

Compared with AP2202K-3.0TRG1 and MCP1700T-3002E/TT, AP130-30WG-7 uniquely balances 300mA continuous output, 50µA quiescent current, and SC59 thermal performance - making it optimal for cost-sensitive, space-constrained, battery-operated devices needing guaranteed full-load regulation without enable logic.

FAQ

What is the minimum input voltage required for AP130-30WG-7 to maintain 3.0V output at 300mA?

The minimum input voltage is 3.4V, calculated as V_OUT + V_DROP = 3.0V + 0.4V (typical dropout at 300mA). At 25°C, the device sustains regulation down to this level; at higher ambient temperatures, dropout increases slightly due to R_ON drift, so design margin should include worst-case 500mV per datasheet.

Can AP130-30WG-7 operate with ceramic output capacitors?

Yes - the AP130-30WG-7 is stable with ceramic capacitors ≥10µF and ESR ≤100mΩ. The datasheet specifies 10µF tantalum as reference, but ceramic equivalents (X5R/X7R) are widely used in production; ensure capacitor voltage rating exceeds 6.3V to accommodate input transients and derating.

Does AP130-30WG-7 require an input capacitor?

Yes - a minimum 1µF ceramic capacitor is required between IN and GND, placed within 5mm of the pins. This reduces high-frequency input impedance, prevents oscillation during load transients, and mitigates noise coupling from upstream power sources such as switching regulators.

Is AP130-30WG-7 compatible with lead-free reflow soldering profiles?

Yes - AP130-30WG-7 is RoHS-compliant and qualified for standard lead-free reflow (J-STD-020D, peak 260°C). The SC59 package withstands three reflow cycles; recommended profile includes ramp rate ≤3°C/s, time above 217°C ≤60 seconds, and peak temperature 245–260°C.
