Product details

Overview

AP130-28YG-13 from Diodes Incorporated is a fixed 2.8V, 300mA low-dropout linear regulator in SOT89-3L package with 400mV dropout at full load, 50µA quiescent current, and ±2% output voltage accuracy-designed for battery-powered wireless modules requiring stable low-noise supply under variable load.

For engineers reviewing the AP130-28YG-13 datasheet, AP130-28YG-13 pinout, AP130-28YG-13 application, or AP130-28YG-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θ_JA = 100°C/W), PSRR (58dB @100Hz), short-circuit fold-back protection, and green RoHS-compliant packaging.

Technical Context

The AP130-28YG-13 uses a PMOS pass element with internal 1.5Ω R_ON, eliminating base drive current and enabling ultra-low quiescent current across load range. Its bandgap-referenced error amplifier delivers fast transient response and tight load regulation (±40mV from 1–300mA).

Integrated current limit (450mA typ) and thermal shutdown prevent damage during fault conditions; short-circuit fold-back reduces power dissipation to 150mA under V_OUT < 1.05V, while built-in stability requires only a 10µF output capacitor.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.8V ±2% - ensures precise biasing for 2.8V logic rails and RF front-end ICs
Max Output Current	300mA continuous - supports moderate-power microcontrollers and transceivers
Dropout Voltage	400mV @300mA - enables operation down to 3.2V input, critical for single-cell Li-ion discharge tail
Quiescent Current	50µA typ @0mA load - minimizes standby power loss in always-on IoT sensors
PSRR	58dB @100Hz - suppresses switching noise from adjacent DC/DC converters
Thermal Resistance θ_JA	100°C/W (SOT89-3L, no heatsink) - defines maximum power dissipation (330mW) at 85°C ambient
Protection Features	Current limit + thermal shutdown + short-circuit fold-back - enables robust operation without external circuitry

Pinout & Package

SOT89-3L package: 3-pin surface-mount, thermally enhanced plastic outline with exposed tab (pin 2 connected to GND for optimal heat transfer). Dimensions: 4.50mm × 2.48mm × 1.50mm (L×W×H), 1.5mm pitch.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT)	Regulated output terminal	Delivers stable 2.8V; requires ≥10µF ceramic capacitor to ground for loop stability
2 (GND)	Ground reference and thermal pad	Must be soldered to large PCB copper area to achieve rated θ_JA = 100°C/W
3 (IN)	Unregulated input supply	Accepts 2.7–5.5V; minimum headroom = 400mV above 2.8V for full 300mA delivery

Key Features

Feature	Design Value
PMOS pass transistor	Zero gate drive current → 50µA I_Q independent of load, ideal for battery longevity
Fast transient response	Stabilizes within 10µs after 100mA step load change - maintains clean supply for digital core switching
Green RoHS-compliant molding	No Br/Sb halogens - meets environmental compliance for consumer and industrial end equipment
Short-circuit fold-back	Limits output current to 150mA during hard short - prevents thermal runaway and PCB trace damage
Lead-free finish	100% matte tin plating - compatible with Pb-free reflow profiles (J-STD-020D)

Applications

Wireless Sensor Node

USB Peripheral Power

Use Scenario: Sub-1GHz LoRaWAN node powered by CR2032 or single-cell Li-ion with intermittent 300mA transmit bursts.

IC Role / Device Role / Timing Role: Primary LDO supplying 2.8V to RF transceiver and MCU core during active transmission.

Use Value: 400mV dropout allows >90% battery utilization down to 3.2V; 50µA I_Q extends shelf life beyond 10 years in sleep mode.

Use Scenario: USB-powered card reader or HID device drawing up to 300mA peak from 5V bus.

IC Role / Device Role / Timing Role: Local 2.8V rail generator decoupling noisy USB switcher output.

Use Value: 58dB PSRR attenuates 100Hz ripple from USB-C PD negotiation; thermal shutdown prevents overheating during sustained read/write.

Industrial Control I/O Module

Embedded Audio Codec Supply

Use Scenario: DIN-rail mounted PLC I/O module with isolated 2.8V analog sensor interface.

IC Role / Device Role / Timing Role: Post-isolation LDO delivering clean 2.8V to precision ADC drivers and op-amps.

Use Value: ±40mV load regulation ensures <0.1% gain error over full 300mA range; ±2% V_OUT accuracy eliminates calibration overhead.

Use Scenario: Portable voice assistant with MEMS microphone array and low-noise audio codec.

IC Role / Device Role / Timing Role: Dedicated 2.8V analog supply for microphone bias and codec AVDD rail.

Use Value: Low 50µA I_Q avoids adding noise floor; fast transient response prevents pop/click during wake-from-sleep audio playback.

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-2802E/TT (Microchip)	250mA max output, 175mV dropout @100mA, 1.6µA I_Q, SOT23-3	Lower current capability; better for ultra-low-I_Q sensor nodes but unsuitable for 300mA bursts	Select when standby current dominates design and peak load ≤250mA
TPS73128DBVR (TI)	300mA, 170mV dropout @100mA, 400mV @300mA, 400µA I_Q, SOT23-5	Higher I_Q; includes enable pin and reverse-current protection not present in AP130	Select when system-level enable control or back-drive prevention is required

Compared with MCP1700T-2802E/TT and TPS73128DBVR, the AP130-28YG-13 uniquely balances 300mA capability, 400mV dropout, and 50µA I_Q in thermally robust SOT89-3L-making it optimal for cost-sensitive, space-constrained battery-powered systems needing full-rated current without enable logic.

FAQ

What is the minimum input voltage required for AP130-28YG-13 to maintain regulation at 300mA?

The AP130-28YG-13 requires a minimum input voltage of 3.2V to sustain 2.8V output at 300mA load, based on its typical 400mV dropout voltage specification. Operation below this threshold results in unregulated output and potential brownout of downstream circuitry.

Can AP130-28YG-13 be used without an output capacitor?

No. The AP130-28YG-13 requires a minimum 10µF ceramic output capacitor connected directly between OUT and GND for stability, as specified in the functional description section of DS31027. Omission causes oscillation and output voltage overshoot during load transients.

Does AP130-28YG-13 support reverse polarity input protection?

No. The AP130-28YG-13 lacks internal reverse-voltage protection. Applying negative voltage to the IN pin or reversing input polarity may cause permanent damage. External protection diode or MOSFET-based reverse-polarity circuitry must be added if required.

How does thermal shutdown activate in AP130-28YG-13?

Thermal shutdown activates when junction temperature exceeds +150°C, disabling the pass transistor until temperature falls below +135°C hysteresis threshold. This occurs under sustained overload or inadequate PCB copper area-verified by θ_JA = 100°C/W rating for SOT89-3L with no heatsink.
