Product details

Overview

AP130-15YRG-13 from Diodes Incorporated is a 300mA fixed-output 1.5V low-dropout linear regulator in SOT89R-3L package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates current limit, thermal shutdown, and short-circuit fold-back protection, and is optimized for battery-powered devices requiring stable low-voltage rail generation.

For engineers reviewing the AP130-15YRG-13 datasheet, AP130-15YRG-13 pinout, AP130-15YRG-13 application, or AP130-15YRG-13 equivalent, key selection considerations include dropout performance at 300mA, thermal resistance (θ_JA = 100°C/W), output voltage tolerance, PSRR (58dB @ 100Hz), and compatibility with 10µF minimum output capacitance for stability.

Technical Context

The AP130-15YRG-13 uses a PMOS pass element with R_ON = 1.5Ω, eliminating base drive current and enabling ultra-low quiescent current (50µA typ). Its error amplifier and bandgap reference maintain regulation across input voltages from 2.7V to 5.5V and load currents from 0 to 300mA.

Internal protection includes thermal shutdown triggered at T_J ≥ 125°C and current limiting at 350–450mA with fold-back behavior below 1.05V output. The device achieves fast transient response due to internal compensation designed for 10µF ceramic output capacitors.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.5V ±2% - ensures precise biasing for 1.5V logic or analog circuitry without external feedback.
Max Output Current	300mA - supports moderate-power peripherals such as USB PHYs or sensor interfaces.
Dropout Voltage	400mV @ 300mA - enables operation from 1.9V input, critical for single-cell Li-ion or alkaline battery systems.
Quiescent Current	50µA typ - minimizes standby power loss in always-on battery applications like remote controls or IoT sensors.
PSRR	58dB @ 100Hz - suppresses ripple from noisy switchers or shared input rails feeding mixed-signal subsystems.
Thermal Resistance θ_JA	100°C/W (SOT89R-3L) - allows continuous 300mA operation up to +85°C ambient with no heatsink.
Protection Features	Current limit (350–450mA), thermal shutdown, short-circuit fold-back - prevents latch-up and damage during fault conditions.

Pinout & Package

SOT89R-3L package: 3-pin surface-mount, exposed thermal pad (not electrically connected), 4.5mm × 2.5mm footprint, 1.5mm height, RoHS-compliant green molding compound.

Pin/Terminal	Circuit Role	Design Meaning
1: GND	Ground reference and thermal path	Primary return for internal circuitry and heat dissipation; must be connected to large copper pour for thermal performance.
2: IN	Input power supply connection	Accepts 2.7–5.5V input; requires ≥1µF bypass capacitor close to pin to suppress high-frequency noise and transients.
3: OUT	Regulated output voltage node	Delivers stable 1.5V; requires ≥10µF output capacitor (ceramic or tantalum) for loop stability and load transient response.

Key Features

Feature	Design Value
PMOS pass transistor	Eliminates base current draw, enabling 50µA IQ independent of load - essential for battery runtime extension.
Internal current limit with fold-back	Reduces short-circuit power dissipation to <150mA level, preventing thermal runaway during sustained overloads.
Guaranteed 300mA output	Validated across -40°C to +85°C ambient, ensuring consistent performance in industrial and automotive accessory environments.
Low line/load regulation	ΔV_LINE = 0.1–0.3%/V and ΔV_LOAD = 30–40mV - maintains tight voltage control despite input sag or dynamic load steps.
Lead-free & green packaging	SOT89R-3L meets RoHS Directive 2002/95/EC and contains no Br/Sb - compliant for global consumer and computing markets.

Applications

Wireless Sensor Node

USB Peripheral Power

Use Scenario: Sub-1W IoT endpoint powered by CR2032 or single-cell Li-ion, operating in sleep/active cycles.

IC Role / Device Role / Timing Role: Primary 1.5V LDO supplying MCU core and RF transceiver, replacing inefficient resistive or switching solutions.

Use Value: 50µA quiescent current extends shelf life >5 years in storage; 400mV dropout enables full discharge down to 1.9V battery voltage.

Use Scenario: Bus-powered USB audio adapter or HID device requiring clean 1.5V rail for DAC or logic interface.

IC Role / Device Role / Timing Role: Local post-regulator isolating sensitive analog circuitry from noisy USB VBUS.

Use Value: 58dB PSRR attenuates 100Hz switching artifacts from upstream DC-DC; ±2% accuracy meets USB compliance for logic-level referencing.

Industrial Control I/O Module

Optical Drive Logic Supply

Use Scenario: DIN-rail mounted PLC I/O board with isolated 1.5V digital logic for optocoupler drivers and status LEDs.

IC Role / Device Role / Timing Role: Dedicated low-noise local regulator for isolated digital domain, decoupled from main 5V system rail.

Use Value: Thermal shutdown (125°C) protects against enclosure overheating; 100°C/W θ_JA sustains 300mA at 70°C ambient without derating.

Use Scenario: CD/DVD-ROM drive PCB where 1.5V powers laser diode control logic and servo amplifiers.

IC Role / Device Role / Timing Role: Secondary LDO delivering stable 1.5V from 3.3V or 5V main rail, rejecting ripple from motor commutation noise.

Use Value: Fast transient response handles 100mA step loads from servo actuation; short-circuit fold-back prevents latch-up during optical head stall events.

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 (Microchip)	250mA max output, 170mV dropout @ 250mA, 1.6µA IQ - lower current, much lower IQ, higher precision (±0.4%)	Best for ultra-low-power microcontroller cores; insufficient for 300mA loads like USB PHYs or servo drivers	Select when IQ <2µA is mandatory and load ≤250mA; avoid if full 300mA capability required.
TPS73115DBVR (TI)	300mA output, 120mV dropout @ 300mA, 400µA IQ - lower dropout, higher IQ, same accuracy (±2%)	Better for sub-2V input systems (e.g., 1.8V rail); higher IQ reduces battery life in always-on use cases	Select when input voltage is tightly constrained (<2.0V) and thermal margin is abundant; avoid if 50µA IQ is critical.

Compared with MCP1700T-1502E/TT and TPS73115DBVR, AP130-15YRG-13 uniquely balances 300mA capability, 400mV dropout, and 50µA IQ - making it optimal for cost-sensitive, thermally constrained 1.5V systems where both current and standby efficiency matter.

FAQ

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

The AP130-15YRG-13 requires a minimum 10µF output capacitor for guaranteed stability across all operating conditions. Ceramic or tantalum types are acceptable; ESR should be between 10mΩ and 1Ω. Lower values risk oscillation under load transients, especially above 100mA step changes.

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

No - the absolute minimum input voltage is 2.7V per the recommended operating conditions. Below this, regulation is not guaranteed, and dropout behavior becomes undefined. At 1.9V input, the device cannot sustain 1.5V output even at zero load due to internal reference and amplifier headroom limitations.

Is the thermal pad on the SOT89R-3L package electrically connected?

No - the exposed thermal pad on the SOT89R-3L package is not electrically connected to any internal node. It serves only for thermal conduction and must be soldered to a large copper area for effective heat dissipation, but no electrical net assignment is required.

Does AP130-15YRG-13 support reverse polarity protection?

No - the AP130-15YRG-13 lacks built-in reverse-polarity protection. Applying reversed input voltage may cause permanent damage. External protection (e.g., series Schottky diode or MOSFET-based ideal diode) is required if reverse input is possible in the system design.
