Product details
Overview
AP7361-15D-13 from Diodes Incorporated is a 1A fixed-output (1.5V) ultra-low dropout linear regulator in TO252 package with enable control, 70µA typical quiescent current, 500mV dropout at 1A load, and thermal shutdown protection-designed for FPGA I/O power, laptop subsystems, and battery-powered audio devices.
For engineers reviewing the AP7361-15D-13 datasheet, AP7361-15D-13 pinout, AP7361-15D-13 application, or AP7361-15D-13 equivalent, key selection criteria include dropout voltage at full load, EN logic thresholds, thermal resistance (95°C/W), output accuracy (±2% over temperature), and ceramic capacitor stability with ≥2.2µF.
Technical Context
The AP7361-15D-13 implements a PMOS pass element with internal 0.8V bandgap reference and error amplifier to regulate fixed 1.5V output. Its enable circuitry requires VIH ≥ 1.0V and VIL ≤ 0.3V for reliable ON/OFF control, and it operates across 2.2V–6.0V input range without minimum load requirement.
Current limiting triggers at 1.1–1.5A and short-circuit protection clamps output to ~200mA; thermal shutdown activates at ~150°C with 20°C hysteresis. PSRR reaches 65dB at 1kHz and 45dB at 10kHz under 100mA load, supporting noise-sensitive analog and digital loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% over -40°C to +85°C ambient - ensures stable core/I/O rail for low-voltage logic. |
| Max Output Current | 1.0A continuous - supports FPGA I/O banks, USB PHYs, and sensor signal chains without external boost. |
| Dropout Voltage | 500mV at 1A load - enables operation from 2.0V input (e.g., single Li-ion cell with aging margin). |
| Quiescent Current | 70µA typical - extends battery runtime in always-on monitoring circuits and portable audio codecs. |
| PSRR | 65dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters feeding mixed-signal systems. |
| Thermal Shutdown | 150°C activation with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Input Voltage Range | 2.2V to 6.0V - compatible with 3.3V, 5V rails and partially discharged 2-cell Li-ion (≈2.4V min). |
Pinout & Package
AP7361-15D-13 uses TO252 (DPAK) package with exposed thermal pad, θJA = 95°C/W on 2"x2" FR-4 board. Pin 1 = IN, Pin 2 = GND, Pin 3 = OUT - no EN or ADJ pins present in this fixed-output variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (IN) | Regulator input | Accepts 2.2–6.0V supply; requires ≥1µF ceramic bypass close to pin to suppress input ripple and EMI. |
| Pin 2 (GND) | Power ground reference | Low-impedance return path for input/output currents; must connect directly to thermal pad and system ground plane. |
| Pin 3 (OUT) | Regulated output | Delivers stable 1.5V; requires ≥2.2µF ceramic capacitor with 10–300mΩ ESR for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 500mV at 1A load enables use with <2.0V headroom - critical for battery-powered systems near end-of-discharge. |
| Ceramic capacitor stability | Stable with ≥2.2µF X5R/X7R ceramic output cap - eliminates need for costly tantalum or electrolytic capacitors. |
| Fast transient response | Load step recovery within microseconds (per typical curves) - maintains regulation during FPGA I/O switching bursts. |
| Integrated protection | Current limit (1.1–1.5A), short-circuit clamp (~200mA), and thermal shutdown (150°C) - reduces external protection component count. |
| Low-noise operation | 65dB PSRR at 1kHz and <130ppm/°C output drift - preserves SNR in ADC reference supplies and audio DAC outputs. |
Applications
| FPGA I/O Power | Laptop Subsystem Rail |

Use Scenario: Powering 1.5V I/O banks of Xilinx Artix-7 or Intel Cyclone V FPGAs during configuration and high-speed data transfer. IC Role / Device Role / Timing Role: Primary low-noise, high-current LDO delivering clean 1.5V to I/O buffers and transceivers. Use Value: Maintains signal integrity with <1% output variation under 100mA–1A dynamic load steps, preventing timing violations. |
Use Scenario: Supplying 1.5V auxiliary rail for USB 3.0 controller, PCIe clock buffer, or embedded controller in thin-and-light notebooks. IC Role / Device Role / Timing Role: Secondary regulated rail decoupled from main CPU VRM, enabling independent power sequencing and fault isolation. Use Value: 70µA quiescent current minimizes standby power draw; 500mV dropout allows operation from shared 2.0V intermediate bus. |
| Battery-Powered Audio Codec | Industrial Sensor Signal Chain |
|
Use Scenario: Providing 1.5V bias to MEMS microphone preamp and stereo ADC in portable voice recorder or smart speaker. IC Role / Device Role / Timing Role: Low-noise analog supply rail with high PSRR to reject switcher noise coupling into audio path. Use Value: 65dB PSRR at 1kHz suppresses DC/DC ripple, reducing audible hiss; ceramic-capacitor compatibility lowers BOM cost. |

IC Role / Device Role / Timing Role: Ultra-stable analog reference rail with <130ppm/°C drift and ±2% accuracy over full industrial temperature range. Use Value: Enables <0.005% total unadjusted error without external trimming; thermal shutdown protects against enclosure overheating faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-1502E/MB | 150mA max output, 600mV dropout at 150mA, SOT-23 package - lower current, higher dropout, smaller footprint. | Suitable only for microcontroller cores or low-power sensors; insufficient for FPGA I/O or audio codecs. | Select when space-constrained and load <150mA; avoid for 1A applications. |
| Torex XC6210B152MR-G | 1A output, 250mV dropout at 300mA, but only 300mA guaranteed at 500mV dropout; SOT-25 package. | Limited thermal performance (θJA >150°C/W); unstable above 300mA without aggressive heatsinking. | Use only with light, intermittent loads; AP7361-15D-13 preferred for sustained 1A operation. |
Compared with MCP1703T-1502E/MB and XC6210B152MR-G, AP7361-15D-13 uniquely delivers 1A continuous current with 500mV dropout and 95°C/W thermal resistance in TO252 - making it the only viable choice for thermally demanding, high-current 1.5V rails.

FAQ
What is the maximum input voltage for AP7361-15D-13?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2.2V to 6.0V. Exceeding 6.0V risks exceeding internal gate oxide limits and may trigger thermal shutdown prematurely due to increased power dissipation. Operation at 6.0V with 1.5V output yields 4.5V drop, demanding careful thermal design.
Does AP7361-15D-13 require an external enable circuit?
No - AP7361-15D-13 lacks an EN pin (TO252 fixed-output variant). It operates continuously when input voltage is applied. For ON/OFF control, a series MOSFET or upstream load switch must be used; alternative packages like AP7361-15FGE-7 include EN functionality.
Can AP7361-15D-13 be used with aluminum polymer capacitors?
Yes, but only if ESR falls within 10–300mΩ and capacitance ≥2.2µF. Ceramic capacitors are strongly preferred due to guaranteed stability, lower ESR drift with temperature, and absence of aging effects. Aluminum polymer caps may cause marginal phase margin in some layouts.
Is the TO252 package lead-free and RoHS compliant?
Yes - AP7361-15D-13 uses totally lead-free construction and fully complies with EU RoHS Directive 2011/65/EU. The molding compound is halogen- and antimony-free ("Green"), containing <900ppm bromine, <900ppm chlorine, and <1000ppm antimony compounds.
