Product details
Overview
AP7365-10ERG-13 from Diodes Incorporated is a fixed-output 1.0V, 600mA low-dropout linear regulator with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It operates from 2V–6V input, delivers ±2% output accuracy across –40°C to +85°C, and stabilizes with only 1μF ceramic output capacitance-ideal for FPGA I/O power and battery-powered portable devices.
For engineers reviewing the AP7365-10ERG-13 datasheet, AP7365-10ERG-13 pinout, AP7365-10ERG-13 application, or AP7365-10ERG-13 equivalent, key selection criteria include dropout voltage under 600mA load, thermal shutdown threshold at +145°C, PSRR of 65dB at 1kHz, EN logic-high threshold ≥1.4V, and SOT223-ER package thermal resistance (θJA = 142°C/W).
Technical Context
The AP7365-10ERG-13 implements a PMOS pass transistor architecture enabling ultra-low quiescent current and fast transient response. Its internal 0.8V bandgap reference and error amplifier regulate output via feedback from the OUT pin in fixed-voltage mode-no external resistors required.
Enable functionality is implemented as a logic-high active input (VIH ≥1.4V) that directly controls the gate driver; thermal shutdown activates at +145°C with +15°C hysteresis, and current limiting clamps output to 1.4A during overload while short-circuit protection limits to 240mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±2% over –40°C to +85°C ambient; enables direct powering of 1.0V FPGA I/O banks without resistor network. |
| Max Output Current | 600mA continuous; sufficient for multi-rail core/I/O domains in compact embedded systems. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥2.5V); for 1.0V output, typical dropout is 370mV-supports operation down to 1.37V input. |
| Quiescent Current | 35μA typical at zero load; minimizes standby power loss in always-on subsystems like real-time clocks or sensor interfaces. |
| PSRR | 65dB at 1kHz; suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Start-Up Time | 200μs from EN high to regulated output; enables rapid wake-up from deep-sleep states in portable applications. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT223-ER package with exposed thermal pad (pin 3 = IN, pin 1 = GND, pin 2 = OUT); optimized for moderate-power dissipation with θJA = 142°C/W on standard FR-4 board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin to suppress high-frequency noise and ensure stability. |
| GND (Pin 1) | Power ground reference | Low-impedance return path for input/output currents; must connect directly to thermal pad and system ground plane. |
| OUT (Pin 2) | Regulated output | Delivers stable 1.0V; requires ≥1μF ceramic capacitor with ESR >15mΩ placed within 2mm of pin for transient response and stability. |
| EN (Not present) | Enable control input | Not implemented in ER-package fixed-output variant; device is always enabled-no external pull-up required. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout with PMOS pass element | Enables operation from single-cell Li-ion (3.0V min) down to 1.37V input for 1.0V output-critical for battery runtime extension. |
| Stable with 1μF ceramic output cap | Reduces BOM count and PCB area vs. traditional LDOs requiring ≥10μF tantalum; eliminates ESR tuning complexity. |
| 65dB PSRR at 1kHz | Attenuates ripple from noisy switchers (e.g., buck converters powering SoC cores), preserving signal integrity in analog/sensor rails. |
| Fast 200μs start-up | Supports dynamic power gating in DSP/FPGA subsystems-enables microsecond-scale entry/exit from low-power states. |
| ±2% output accuracy over temp | Meets tight voltage tolerance requirements for 1.0V I/O standards (e.g., LVCMOS, SSTL-12) without external calibration. |
Applications
| FPGA I/O Power | Portable Medical Sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7361-10W5G-7 | SOT25 package (θJA = 169°C/W), lower max current (300mA), same 1.0V output and 35μA IQ. | Restricted to low-power logic rails (<300mA); unsuitable for FPGA I/O or processor cores. | Select when board space is constrained and thermal budget permits higher junction rise. |
| MCP1700-1002E/MB | Microchip 200mA LDO; 1.0V fixed, 1.6μA IQ, but only 175mV dropout at 250mA-lower efficiency at 600mA. | Optimized for micropower sensor nodes, not medium-current applications; lacks current limit/thermal shutdown robustness. | Choose only for sub-200mA always-on sensors where nanoamp IQ outweighs current capability. |
Compared with AP7365-10ERG-13, AP7361-10W5G-7 trades thermal performance for smaller footprint, while MCP1700-1002E/MB sacrifices output current and protection features for ultra-low IQ-neither matches the 600mA/35μA/300mV triplet in SOT223-ER form factor.

FAQ
Is AP7365-10ERG-13 pin-compatible with other AP7365 variants in SOT223?
Yes-AP7365-10ERG-13 uses the ER variant SOT223 pinout (IN=3, GND=1, OUT=2) matching all fixed-output SOT223 versions (E, ER, EV). The adjustable SOT223 variants are not offered; only SOT25 and U-DFN2020-6 support ADJ configuration.
What is the minimum input voltage required to maintain 1.0V output at 600mA?
The minimum input is 1.37V, calculated from the typical 370mV dropout voltage for VOUT < 2.5V at 600mA load. At worst-case 600mV dropout (per datasheet max), VIN must be ≥1.6V to sustain regulation under full load and temperature extremes.
Can AP7365-10ERG-13 be used without an enable signal?
Yes-the ER package fixed-output variant has no EN pin. It operates continuously when powered; no external pull-up or control logic is needed. This simplifies design for always-on rails but removes dynamic power gating capability.
Does the SOT223-ER package require soldering the thermal pad to PCB ground?
Yes-the exposed thermal pad (connected internally to GND) must be soldered to a dedicated PCB copper pour tied to system ground. Omitting this reduces θJA by ~30°C/W and risks thermal shutdown under sustained 600mA load at elevated ambient temperatures.
