Product details
Overview
AP7365-12ERG-13 from Diodes Incorporated is a fixed-output 1.2V, 600mA low-dropout linear regulator in SOT223-3 (ER) package with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable core voltage for FPGA I/O banks and DSP subsystems in battery-powered industrial controllers where low standby power and fast transient response are critical.
For engineers reviewing the AP7365-12ERG-13 datasheet, AP7365-12ERG-13 pinout, AP7365-12ERG-13 application, or AP7365-12ERG-13 equivalent, key selection criteria include dropout voltage at 600mA, EN logic thresholds, thermal shutdown hysteresis, PSRR at 1kHz, and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7365-12ERG-13 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA, VOUT ≥ 2.5V; 370mV @ 600mA, VOUT < 2.5V) and high PSRR (65dB @ 1kHz). Its bandgap reference and error amplifier maintain ±2% output accuracy across –40°C to +85°C ambient.
Enable functionality uses TTL-compatible thresholds (VIH = 1.4V min, VIL = 0.4V max), while built-in protection includes current limiting (1.4A typ), short-circuit clamping (240mA typ), and thermal shutdown (145°C trip, 15°C hysteresis).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±2% over –40°C to +85°C; enables direct powering of 1.2V FPGA I/O rails without external resistors. |
| Max Output Current | 600mA continuous; supports single-rail supply for mid-power digital subsystems without derating at 85°C ambient. |
| Quiescent Current | 35μA typical; reduces standby power loss in always-on sensor nodes and IoT edge devices. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); allows operation from 1.5V input for 1.2V output, extending battery runtime in 2-cell alkaline systems. |
| PSRR | 65dB at 1kHz; suppresses switching noise from upstream DC/DC converters feeding sensitive analog or RF circuitry. |
| Start-Up Time | 200μs typical; enables rapid wake-up from deep-sleep modes in portable medical monitors and handheld test equipment. |
| Thermal Shutdown | 145°C junction trip with 15°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT223-3 (ER Package) with exposed thermal pad on underside; requires minimum 1oz copper thermal plane per Diodes' recommended layout for θJA = 142°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output voltage node | Must be bypassed with ≥1μF ceramic capacitor placed adjacent to pin; connects directly to load VCC rail. |
| GND (Pin 2) | Power ground reference | Low-impedance return path for load current and internal bias; ties to thermal pad for heat dissipation. |
| IN (Pin 3) | Unregulated input supply | Requires ≥1μF MLCC decoupling; supports 2V–6V input range, enabling use with Li-ion, USB, or buck converter outputs. |
| EN (Pin 4) | Enable control input | Active-high logic interface; must exceed 1.4V to enable regulation; tied to IN if always-on operation is required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA quiescent current enables >1-year battery life in coin-cell-powered remote sensors with periodic wake-ups. |
| Fast transient response | Stable under 10mA ↔ 600mA load steps with <200mV undershoot/overshoot; sustains clean supply for GSM baseband processors. |
| 1μF ceramic stability | No minimum ESR requirement; eliminates need for costly tantalum or polymer capacitors in space-constrained designs. |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown prevent field failures in unattended industrial deployments. |
| Wide input range | 2V–6V operation supports direct connection to 2.4V–5.5V sources including USB PD, boost converters, and multi-cell batteries. |
Applications
| Industrial PLC I/O Modules | FPGA Core & I/O Power |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7361-12YG-13 | Lower 300mA output current; identical 1.2V output, 35μA IQ, and SOT89 package; no EN pin. | Lacks enable control; unsuitable for power-gated subsystems requiring dynamic turn-on/off. | Select when board space permits SOT89 and EN functionality is unnecessary to reduce component count. |
| MCP1703T-1202E/MB | Higher 250mV dropout at 250mA; 4μA IQ; SOT89-3; no thermal shutdown; 1.2V ±1% accuracy. | Superior IQ but lacks fault protection; not rated for industrial temperature range (–40°C to +125°C only). | Choose only for ultra-low-power, non-safety-critical consumer applications where thermal margin is guaranteed. |
Compared with AP7365-12ERG-13, AP7361-12YG-13 trades current capability and EN control for smaller footprint, while MCP1703T-1202E/MB sacrifices protection features and thermal robustness for ultra-low IQ-neither matches the balanced performance envelope of the AP7365 for industrial-grade 1.2V regulation.

FAQ
What is the minimum input voltage required for stable 1.2V output at 600mA?
The AP7365-12ERG-13 requires VIN ≥ VOUT + VDROPOUT = 1.2V + 0.3V = 1.5V minimum for full-load regulation. However, the datasheet specifies a 2V absolute minimum input voltage to ensure internal circuitry biasing and PSRR performance; operation below 2V is not guaranteed.
Can the EN pin be left floating, or must it be actively driven?
The EN pin must never be left floating: its internal pull-down is insufficient to guarantee turn-off. To ensure reliable operation, tie EN directly to IN for always-on use, or drive it with a clean logic signal meeting VIH ≥ 1.4V and VIL ≤ 0.4V. Floating EN risks erratic enable/disable behavior due to noise coupling.
Is the SOT223-3 (ER) package thermally compatible with standard FR-4 PCBs without an extended copper pour?
No. The SOT223-3 (ER) package has θJA = 142°C/W on a standard 1oz FR-4 board with minimum pad layout. Without a dedicated thermal plane connected to the exposed tab, power dissipation above ~300mW will trigger thermal shutdown at 85°C ambient. A ≥1cm² copper area is mandatory for 600mA operation.
Does the 1.2V output version support adjustable output via external resistors?
No. The AP7365-12ERG-13 is a fixed-output variant; only SOT25 and U-DFN2020-6 packages offer adjustable versions with ADJ pin. Attempting to connect resistors to the OUT pin of this part will disrupt regulation and may cause instability or overvoltage.
