Product details

Overview

AP130-15WL-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 integrates PMOS pass element with no base current draw, thermal shutdown, and current-limit protection-designed for battery-powered portable electronics requiring stable low-voltage rail generation.

For engineers reviewing the AP130-15WL-7 datasheet, AP130-15WL-7 pinout, AP130-15WL-7 application, or AP130-15WL-7 equivalent, key selection criteria include dropout voltage under 300mA load, guaranteed 1.5V output tolerance, SC59 footprint compatibility, thermal resistance (θ_JA = 250°C/W), and RoHS-compliant green molding compound.

Technical Context

The AP130-15WL-7 employs a PMOS pass transistor architecture enabling zero gate-drive current and inherently low quiescent consumption. Its error amplifier uses an internal 1.08V bandgap reference to regulate output against line and load variations.

Protection circuitry includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered at ~125°C junction temperature. Stability requires ≥10µF ceramic output capacitance per functional description.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.5V ±2% - ensures precise core logic or analog supply for 1.5V I/O domains.
Max Output Current	300mA continuous - supports moderate-power microcontrollers, sensors, or interface ICs.
Dropout Voltage	400mV typ. at 300mA - enables operation down to 1.9V input, critical for single-cell Li-ion or alkaline systems.
Quiescent Current	50µA typ. at zero load - minimizes standby power loss in always-on battery applications.
PSRR	58dB at 100Hz - suppresses ripple from noisy switchers or shared input rails.
Line Regulation	0.1–0.3%/V - maintains output stability across input voltage sag during battery discharge.
Thermal Resistance θ_JA	250°C/W (SC59) - defines maximum power dissipation (125mW at ΔT=31.25°C rise) on standard FR-4 board.

Pinout & Package

AP130-15WL-7 is housed in SC59 package (3-pin SOT-23 variant), with 2.7mm × 2.9mm footprint and 1.3mm height. Pin 1 = IN, Pin 2 = OUT, Pin 3 = GND (top view, left-to-right).

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Input Power Supply	Accepts 2.7–5.5V; must be decoupled with ≥1µF capacitor to limit transient sag.
2 (OUT)	Regulated Output	Delivers stable 1.5V; requires ≥10µF low-ESR ceramic capacitor to ground for loop stability.
3 (GND)	Ground Reference	Common return path for input/output capacitors and load; low-inductance layout essential for PSRR.

Key Features

Feature	Design Value
PMOS Pass Element	Zero gate drive current eliminates base/charge pump losses, enabling ultra-low IQ operation.
Current Limit + Thermal Shutdown	Protects against sustained overloads and PCB-level thermal runaway without external components.
Fold-Back Short-Circuit Protection	Reduces output current to 150–300mA during fault, limiting power dissipation and junction temperature rise.
Green Molding Compound	Halogen-free (no Br/Sb), compliant with environmental standards for consumer and industrial end equipment.
Lead-Free & RoHS Compliant	Meets EU Directive 2002/95/EC exemptions; suitable for global commercial and industrial shipments.

IC Role / Device Role / Timing Role: Primary 1.5V LDO supplying MCU core and RF transceiver logic.

Use Value: 50µA quiescent current extends shelf life; 400mV dropout allows >20% deeper battery discharge before brownout.

Use Scenario: USB 2.0 hub or HID device drawing <300mA from VBUS.

IC Role / Device Role / Timing Role: Local 1.5V rail generator for USB PHY or microcontroller I/O bank.

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
MCP1700-1502E/TO	250mA max output, 175mV dropout at 250mA, 1.6µA IQ - lower current, much lower dropout, ultra-low IQ.	Best for sub-250mA ultra-low-power designs where 1.5V precision and minimal quiescent drain are primary.	Select when system load is ≤250mA and battery life outweighs current capability.
TPS7A0515PDBVR	200mA max, 175mV dropout at 200mA, 25µA IQ, integrated enable - higher integration, lower IQ, lower current rating.	Suitable for space-constrained designs needing enable control and tighter dropout, but not for 300mA loads.	Choose if board space is limited and enable functionality is required; avoid for >200mA peak loads.

Compared with MCP1700-1502E/TO and TPS7A0515PDBVR, AP130-15WL-7 delivers higher output current (300mA vs. ≤250mA), wider input range (2.7–5.5V), and proven thermal robustness in SC59 - making it optimal for cost-sensitive, medium-current portable applications where full 300mA capability and legacy footprint compatibility matter.

FAQ

What is the minimum input voltage required for AP130-15WL-7 to maintain regulated 1.5V output at 300mA?

The minimum input voltage is calculated as V_OUT + V_DROP = 1.5V + 0.4V = 1.9V. Per datasheet specifications, dropout is guaranteed at 400mV typ. and 500mV max at 300mA, so 1.9V–2.0V input ensures regulation across process and temperature variation. Operation below 2.7V input is permitted but not characterized for line regulation.

Can AP130-15WL-7 be used with ceramic output capacitors only?

Yes - the AP130-15WL-7 is explicitly designed for stability with ≥10µF ceramic output capacitors (low ESR). The datasheet specifies "a minimum of 10µF capacitor must be connected from OUT to ground to insure stability," and typical performance curves confirm stable operation with ceramic types. No tantalum or electrolytic capacitor is required.

Does AP130-15WL-7 require an input capacitor, and what value is recommended?

Yes - a minimum 1µF ceramic input capacitor is required, placed close to the IN and GND pins. This limits input voltage sag during load transients and improves PSRR. The datasheet's typical application circuit shows 1µF at VIN, and electrical characteristics testing assumes C_IN = 1µF. Larger values (e.g., 4.7–10µF) further improve transient response without risk of instability.

Is AP130-15WL-7 compatible with lead-free reflow soldering profiles?

Yes - AP130-15WL-7 is lead-free and RoHS compliant (per Note 1), qualified for standard JEDEC J-STD-020D reflow profiles. Its SC59 package supports peak temperatures up to 260°C for 10 seconds. The "L" suffix denotes lead-free plating, and "G" or "W" suffixes indicate green or standard lead-free molding compound per ordering information.
