Product details

Overview

AP130-30YRL-13 from Diodes Incorporated is a 300mA fixed-output 3.0V 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, and is optimized for battery-powered devices requiring stable low-noise voltage regulation.

For engineers reviewing the AP130-30YRL-13 datasheet, AP130-30YRL-13 pinout, AP130-30YRL-13 application, or AP130-30YRL-13 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θ_JA = 100°C/W), output voltage tolerance, short-circuit fold-back behavior, and RoHS-compliant green molding compound compatibility with IPC-J-STD-020 reflow profiles.

Technical Context

The AP130-30YRL-13 uses an internal PMOS pass transistor with 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 over 1–300mA).

Protection circuitry includes thermal shutdown triggered at T_J ≥ 125°C and current limit set to 350–450mA with fold-back during short-circuit events. Input voltage range is strictly 2.7V to 5.5V, and stability requires ≥10µF ceramic or tantalum output capacitance.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0V ±2% at 1mA, ensuring precise rail generation for 3.3V-tolerant logic without external feedback.
Dropout Voltage	400mV typ. at 300mA, enabling operation down to 3.4V input for 3.0V output-critical for single-cell Li-ion or dual-cell alkaline systems.
Quiescent Current	50µA typ. at zero load, minimizing standby power loss in always-on battery applications like remote sensors.
PSRR	58dB at 100Hz, suppressing low-frequency ripple from switching DC/DC stages upstream of the LDO.
Thermal Resistance θ_JA	100°C/W (SOT89-3L, no heatsink), defining maximum power dissipation (P_D ≤ 900mW at T_A = 85°C) before thermal shutdown.
Current Limit	350–450mA, limiting fault current while maintaining fold-back to reduce power dissipation during sustained short circuits.
Line Regulation	0.1–0.3%/V, ensuring output stability despite input variations from aging batteries or unregulated supplies.

Pinout & Package

SOT89-3L package: 3-pin surface-mount, thermally enhanced plastic case with exposed tab (pin 2) connected to GND for improved heat dissipation. Dimensions: 4.50 × 2.48 × 1.50 mm (L × W × H), compatible with standard SMT pick-and-place and reflow processes.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT)	Regulated Output	Delivers stable 3.0V to load; requires ≥10µF low-ESR capacitor to ground for loop stability.
2 (GND)	Ground Reference & Thermal Pad	Common return path and primary thermal conduction path to PCB copper; must be soldered to ≥1 cm² thermal pad.
3 (IN)	Input Supply	Accepts 2.7–5.5V; minimum headroom of 400mV required above V_OUT to maintain regulation at 300mA.

Key Features

Feature	Design Value
PMOS Pass Element	1.5Ω R_ON enables zero gate-drive current, reducing system-level bias power and simplifying layout vs. NPN-based LDOs.
Fast Transient Response	Stabilizes within <10µs after 100mA step load change, preserving signal integrity in burst-mode wireless peripherals.
Short-Circuit Fold-Back	Reduces output current to 150–300mA under hard short, limiting junction temperature rise and enabling safe auto-recovery.
Green Molding Compound	Halogen-free (Br/Sb-free), compliant with IPC-1752 and JEDEC J-STD-020, supporting lead-free assembly and environmental compliance.
Thermal Shutdown	Activates at T_J ≥ 125°C and holds until die cools by ≥15°C, preventing permanent damage during sustained overload.

Applications

Wireless Sensor Node

USB Peripheral Power

Use Scenario: Sub-1W IoT sensor node powered by CR2032 or single Li-ion cell, operating intermittently with BLE or Zigbee radio bursts.

IC Role / Device Role / Timing Role: Primary 3.0V supply regulator for MCU, RF transceiver, and analog front-end; maintains regulation during RF transmit current spikes.

Use Value: 50µA quiescent current extends battery life beyond 5 years in sleep-dominated duty cycles; 400mV dropout enables use of depleted cells down to 3.4V.

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

IC Role / Device Role / Timing Role: Local 3.0V rail generator isolating sensitive logic from USB port noise and voltage droop.

Use Value: 58dB PSRR at 100Hz suppresses USB switcher ripple; thermal shutdown prevents overheating during sustained read/write operations.

Optical Drive Logic Supply

Industrial Control I/O Module

Use Scenario: CD/DVD-ROM drive logic board requiring clean 3.0V for servo control ICs and buffer memory.

IC Role / Device Role / Timing Role: Post-regulator downstream of main 5V DC/DC converter, filtering high-frequency switching noise.

Use Value: Tight ±2% output accuracy ensures reliable SRAM and microcontroller operation; fast transient response prevents brownout during laser activation.

Use Scenario: DIN-rail mounted PLC I/O module with isolated 3.0V logic rail for digital input conditioning and status LEDs.

IC Role / Device Role / Timing Role: Secondary regulated supply for optocoupler drivers and level-shifting interfaces in noisy industrial environments.

Use Value: Current-limit + thermal shutdown protects against field wiring faults; -40°C to +85°C ambient rating supports wide-temperature deployment.

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-3002E/TT (Microchip)	250mA rated, 175mV dropout at 250mA, 2.5µA quiescent current, SOT23-3 package.	Limited to lower current loads; superior IQ for ultra-low-power sleep modes but insufficient for 300mA peaks.	Select when peak load ≤250mA and standby current is critical; not suitable for sustained 300mA operation.
TPS73030DBVR (TI)	200mA rated, 120mV dropout at 200mA, 330µA IQ, SOT23-5 with enable pin.	Includes active-high EN pin and higher IQ; lower thermal margin due to smaller SOT23-5 footprint (θ_JA ≈ 200°C/W).	Choose only if enable functionality is required and load current remains ≤200mA; avoid in thermally constrained layouts.

Compared with MCP1700T-3002E/TT and TPS73030DBVR, AP130-30YRL-13 uniquely balances 300mA capability, 400mV dropout, and 50µA IQ in a thermally robust SOT89-3L package-making it optimal for cost-sensitive, medium-current battery or USB-powered applications where thermal headroom and load margin are essential.

FAQ

What is the minimum input voltage required for AP130-30YRL-13 to maintain 3.0V regulation at 300mA?

The minimum input voltage is 3.4V, calculated as V_OUT + V_DROP = 3.0V + 0.4V. Below this, the device enters dropout and output voltage declines linearly with input. This headroom requirement is verified per DS31027 Rev. 8–2, page 4, Table "Electrical Characteristics" under V_DROP test condition IL = 300mA.

Can AP130-30YRL-13 operate without an input capacitor?

No-while the datasheet specifies C_IN = 1µF for testing, a minimum 1µF X5R/X7R ceramic capacitor is required at the IN pin to prevent oscillation and ensure stability under fast load transients. Omission risks startup overshoot, ringing, or thermal runaway during high di/dt events.

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

Yes-the exposed thermal pad (pin 2) is internally connected to GND. It must be soldered to a dedicated PCB ground plane with ≥1 cm² copper area to achieve the specified θ_JA = 100°C/W and prevent thermal shutdown under full 300mA load.

Does AP130-30YRL-13 support reverse polarity protection?

No-it lacks internal reverse-voltage blocking. Applying negative voltage to IN or OUT relative to GND may cause latch-up or permanent damage. External protection (e.g., series Schottky diode on IN) is required in systems with potential reverse-battery or hot-swap conditions.
