Product details

Overview

AP130-15WG-7 from Diodes Incorporated is a 300mA fixed-output 1.5V low-dropout linear regulator in SC59 package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It employs a PMOS pass element with no base current draw, enabling efficient operation in battery-powered portable electronics requiring stable low-voltage rail generation.

For engineers reviewing the AP130-15WG-7 datasheet, AP130-15WG-7 pinout, AP130-15WG-7 application, or AP130-15WG-7 equivalent, key selection criteria include dropout voltage under 300mA load, thermal shutdown behavior, PSRR at 100Hz, load regulation performance across 1–300mA, and SC59 footprint compatibility with existing PCB layouts.

Technical Context

The AP130-15WG-7 integrates a bandgap reference, error amplifier, and PMOS pass transistor in a monolithic IC architecture optimized for low-noise, low-quiescent-current regulation. Its internal current-limit circuit uses fold-back protection, and thermal shutdown activates at junction temperatures exceeding +125°C.

Designed for input voltages from 2.7V to 5.5V, it delivers regulated 1.5V output with <40mV load regulation (1–300mA) and 58dB power supply ripple rejection at 100Hz - critical for noise-sensitive analog and RF subsystems powered from shared switched-mode rails.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.5V ±2% - ensures precise biasing for 1.5V logic, memory I/O, or sensor interfaces without external feedback.
Max Output Current	300mA continuous - supports moderate-power microcontrollers, USB peripherals, or small displays without thermal derating in SC59.
Dropout Voltage	400mV typ. at 300mA - enables regulation from 1.9V input, extending usable battery life in single-cell Li-ion or alkaline systems.
Quiescent Current	50µA typ. at zero load - minimizes standby power loss in always-on circuits like real-time clocks or wake-up controllers.
PSRR	58dB at 100Hz - suppresses switching noise from upstream DC/DC converters feeding mixed-signal SoCs or ADCs.
Thermal Shutdown	Activates at TJ > +125°C - protects device during sustained overload or poor PCB heatsinking in compact enclosures.
Line Regulation	0.1–0.3%/V - maintains output stability despite input sag during high-current transients in portable devices.

Pinout & Package

AP130-15WG-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 resistance θ_JA is 250°C/W on standard FR-4 board per Diodes' recommended pad layout.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Power Input	Accepts 2.7–5.5V unregulated input; requires ≥1µF ceramic bypass capacitor placed near pin for stability and transient response.
2 (OUT)	Regulated Output	Delivers fixed 1.5V ±2%; must be decoupled with ≥10µF low-ESR capacitor to ground to prevent oscillation under load steps.
3 (GND)	Ground Reference	Common return path for input/output capacitors and load; connects internally to substrate; requires low-impedance PCB trace to minimize noise coupling.

Key Features

Feature	Design Value
PMOS Pass Element	Zero gate drive current eliminates base current loss, improving efficiency over bipolar LDOs especially at light loads.
Fast Transient Response	Stabilizes within microseconds after 100mA load step due to internal compensation and low output impedance.
Short-Circuit Fold-Back	Limits output current to ~150–300mA during hard shorts, reducing power dissipation and preventing thermal runaway.
Green Molding Compound	Halogen-free (no Br/Sb) epoxy meets environmental compliance requirements for consumer and industrial end equipment.
Current Limit Protection	Guarantees 350–450mA trip threshold, allowing safe operation up to rated 300mA while blocking fault currents.

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-1502E/TT	250mA max output, 175mV dropout at 250mA, 1.6µA quiescent current	Lower IQ ideal for multi-year battery life; lower current rating limits use in higher-load peripherals	Select when ultra-low standby power dominates over peak current capability
TPS73115DBVR	300mA output, 120mV dropout at 300mA, 400µA IQ, SOT-23-5 package	Lower dropout enables 1.62V minimum input; higher IQ increases standby loss; extra enable pin adds control flexibility	Select when input voltage is marginal (<2.0V) and system-level enable sequencing is required

Compared with MCP1700T-1502E/TT and TPS73115DBVR, AP130-15WG-7 offers balanced performance: higher current than MCP1700 with significantly lower IQ than TPS73115, all in a 3-pin SC59 footprint that simplifies layout versus 5-pin alternatives.

FAQ

What is the minimum input voltage required for AP130-15WG-7 to maintain regulation at 300mA load?

The AP130-15WG-7 requires a minimum input voltage of 1.9V to sustain 1.5V output under 300mA load, based on its typical 400mV dropout voltage. Operation below this threshold results in pass transistor saturation and unregulated output collapse. Input must remain ≥2.7V per absolute maximum ratings to avoid damage.

Can AP130-15WG-7 be used without an output capacitor?

No - a minimum 10µF low-ESR ceramic or tantalum capacitor is mandatory from OUT to GND for stability, as confirmed in the functional description section of DS31027 Rev. 8-2. Omission causes oscillation, excessive output ripple, and potential thermal failure under load.

Does AP130-15WG-7 support reverse polarity or reverse current protection?

No - the AP130-15WG-7 lacks integrated reverse-polarity or reverse-current blocking. If input voltage can fall below output (e.g., during hot-swap or battery removal), an external Schottky diode in series with IN is required to prevent backfeed and possible damage to upstream sources.

How does thermal shutdown behave during sustained overload conditions?

Under sustained overload, AP130-15WG-7 activates thermal shutdown when junction temperature exceeds +125°C, disabling the pass transistor until die temperature falls by ~15°C. This hysteresis prevents rapid cycling and allows safe cooldown; recovery is automatic with no external reset required.
