Product details

Overview

AP130-15YL-13 from Diodes Incorporated is a 300mA fixed-output 1.5V low-dropout linear regulator in SOT89-3L package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates PMOS pass element, thermal shutdown, and current-limit protection for battery-powered peripherals and embedded power rails.

For engineers reviewing the AP130-15YL-13 datasheet, AP130-15YL-13 pinout, AP130-15YL-13 application, or AP130-15YL-13 equivalent, key selection criteria include dropout voltage under 300mA load, guaranteed output accuracy across temperature, thermal resistance (θ_JA = 100°C/W), and compatibility with 10µF minimum output capacitance for stability.

Technical Context

The AP130-15YL-13 uses a PMOS pass transistor with no base current draw, enabling ultra-low quiescent current (50µA typ.) independent of load. Its internal bandgap reference and error amplifier deliver tight regulation-±2% initial accuracy and 50–150 ppm/°C temperature coefficient.

Protection circuitry includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered above +125°C junction temperature. Load regulation remains within ±40mV from 1mA to 300mA, and PSRR reaches 58dB at 100Hz with 1µF input and 10µF output capacitors.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.5V ±2% at 1mA, ensuring stable core voltage for low-power microcontrollers.
Max Output Current	300mA continuous, sufficient for USB-powered peripherals and sensor nodes.
Dropout Voltage	400mV typ. at 300mA, enabling operation down to 1.9V input for single-cell Li-ion or two-cell alkaline systems.
Quiescent Current	50µA typ. at zero load, minimizing standby power loss in always-on IoT endpoints.
PSRR	58dB at 100Hz, suppressing ripple from noisy switchers or shared DC rails.
Thermal Resistance θ_JA	100°C/W (SOT89-3L, no heatsink), defining maximum power dissipation (300mW) before thermal shutdown.
Protection	Current limit + thermal shutdown + short-circuit fold-back, preventing latch-up or destruction during fault conditions.

Pinout & Package

SOT89-3L package: 3-pin surface-mount, thermally enhanced leadframe with exposed pad (not electrically connected), footprint optimized for PCB heat spreading without external heatsink.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT)	Regulated output	Delivers stable 1.5V; requires ≥10µF ceramic capacitor to ground for loop stability.
2 (GND)	Ground reference	Low-impedance return path; connects to thermal pad for improved heat dissipation.
3 (IN)	Input supply	Accepts 2.7–5.5V; must be decoupled with ≥1µF capacitor near pin to suppress transients.

Key Features

Feature	Design Value
PMOS pass element	Eliminates base drive current, enabling 50µA IQ independent of load-critical for battery runtime.
Fast transient response	Maintains <±2% output deviation during 100mA step loads, supporting burst-mode digital ICs.
Green molding compound	Halogen-free, RoHS-compliant package (no Br/Sb), meeting IPC-1752A environmental requirements.
Internal current limit	350–450mA threshold with fold-back behavior, limiting fault power to safe levels during shorts.

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-15W5	250mA max output, SOT23-5 package, 300mV dropout at 150mA	Limited to lower-current logic rails; smaller footprint but higher thermal resistance (200°C/W)	Select when board space is constrained and load ≤250mA; verify thermal margin with 200°C/W θ_JA.
MCP1700T-1502E/TT	250mA, 1.5V fixed, 6µA IQ, SOT23-3 package	Ultra-low IQ ideal for energy harvesting; lower current rating and no thermal shutdown	Prefer for micropower applications where fault protection is handled externally; not suitable for 300mA continuous loads.

Compared with AP2202K-15W5 and MCP1700T-1502E/TT, the AP130-15YL-13 uniquely balances 300mA capability, integrated thermal/current protection, and 100°C/W thermal performance in SOT89-3L-making it optimal for mid-power industrial and peripheral designs where reliability and thermal headroom are critical.

FAQ

What is the minimum output capacitance required for stability with AP130-15YL-13?

A minimum 10µF ceramic capacitor is required between OUT and GND to ensure loop stability across all operating conditions. The datasheet specifies this value based on phase margin testing with typical ESR and ESL characteristics; using lower values may cause oscillation or poor transient response.

Does AP130-15YL-13 require an input capacitor, and if so, what value?

Yes-a minimum 1µF ceramic capacitor is recommended between IN and GND, placed as close as possible to the IN pin. This reduces input impedance at high frequencies, prevents voltage sag during load transients, and improves PSRR performance per the datasheet test conditions.

Can AP130-15YL-13 operate with an input voltage below 2.7V?

No-the absolute minimum input voltage is 2.7V per the Recommended Operating Conditions table. Operation below this risks improper regulation or dropout failure; at 1.5V output, the lowest functional input is 1.9V (1.5V + 400mV dropout), but the device is not characterized or guaranteed below 2.7V.

Is the exposed pad on the SOT89-3L package electrically connected?

No-the exposed pad on the AP130-15YL-13's SOT89-3L package is a thermal pad only, not electrically connected to any internal node. It must be soldered to a large copper pour for thermal conduction but should not be tied to IN, OUT, or GND to avoid short circuits.
