Product details
Overview
AP7365-12SNG-7 from Diodes Incorporated is a fixed-output 1.2V, 600mA low-dropout linear regulator in U-DFN2020-6 package, featuring 35μA quiescent current, 300mV dropout at full load, and fast 200μs startup. It integrates enable control, thermal shutdown, and current limiting, and is optimized for battery-powered FPGA I/O rails and portable consumer electronics requiring stable low-voltage bias.
For engineers reviewing the AP7365-12SNG-7 datasheet, AP7365-12SNG-7 pinout, AP7365-12SNG-7 application, or AP7365-12SNG-7 equivalent, key selection criteria include dropout voltage at 600mA, PSRR at 1kHz, EN logic thresholds, thermal resistance (θJA = 132°C/W), and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7365-12SNG-7 implements a PMOS pass transistor architecture enabling low dropout and high PSRR (65dB @ 1kHz) without external compensation. 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, VIL ≤ 0.4V), and internal protection includes foldback current limiting (1.4A typical), short-circuit clamping (240mA), and thermal shutdown activation at +145°C with +15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±2% over temperature and load - ensures stable core/I/O bias for low-power digital ICs. |
| Max Output Current | 600mA continuous - supports FPGA I/O banks, microcontroller peripherals, and sensor signal chains. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); 370mV max (VOUT < 2.5V) - enables operation down to 1.5V input for 1.2V rail. |
| Quiescent Current | 35μA typical (0–6V input range) - extends battery life in always-on wearable and IoT edge nodes. |
| PSRR | 65dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Startup Time | 200μs from EN high to regulated output - meets real-time wake-up requirements in power-gated systems. |
| Thermal Resistance | θJA = 132°C/W (U-DFN2020-6) - requires minimal PCB copper area for thermal management in space-constrained designs. |
Pinout & Package
AP7365-12SNG-7 is housed in a 2.0mm × 2.0mm, 0.65mm height, thermally enhanced U-DFN2020-6 package with exposed thermal pad (pin 1 = IN, pin 2 = OUT, pin 3 = GND, pin 4 = EN, pin 5 = NC, pin 6 = ADJ). The ADJ pin is internally connected to GND for fixed-output variants and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin for stability and noise rejection. |
| 2 (OUT) | Regulated output | Delivers fixed 1.2V; stable with ≥1μF ceramic capacitor (ESR >15mΩ); connects directly to load. |
| 3 (GND) | Ground reference | Common return path for IN, OUT, and internal circuitry; must be tied to low-impedance system ground plane. |
| 4 (EN) | Enable control input | Active-high logic; drives ON when ≥1.4V, OFF when ≤0.4V; tie to IN if always-on operation required. |
| 5 (NC) | No connection | Internally unconnected; must be left floating or grounded per layout best practice - no routing or soldering. |
| 6 (ADJ) | Feedback reference | Internally tied to GND for fixed-output version; must not be connected externally to avoid regulation error. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA quiescent current enables >1-year battery life in coin-cell-powered sensors with 10μA average load. |
| Fast transient response | Stable under 10mA ↔ 600mA load steps with <20mV undershoot/overshoot - critical for GSM/TDMA baseband power rails. |
| Single-capacitor stability | Guaranteed stable with 1μF ceramic output capacitor - eliminates need for costly tantalum or large MLCC arrays. |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) prevent field failures without external circuitry. |
| Wide input range | 2V–6V operation supports single-cell Li-ion (3.0–4.2V), two-cell alkaline (2.0–3.2V), and USB-powered systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-1202E/TO | 300mA max output, 2μA IQ, SOT23-5 package, higher dropout (600mV @ 250mA) | Limited to ultra-low-power MCU cores; insufficient for FPGA I/O or radio transmit loads | Select only for sub-100mA, nanowatt-sleep applications where IQ dominates lifetime analysis. |
| Torex XC6210B122MR-G | 1A output, 15μA IQ, SOT25 package, 200mV dropout @ 1A, but no EN pin | Requires external MOSFET for enable control; larger footprint than U-DFN2020-6 | Prefer when higher current headroom is needed and board space permits SOT25; avoid if EN functionality is mandatory. |

FAQ
What is the minimum input voltage required for AP7365-12SNG-7 to regulate 1.2V output at 600mA?
The minimum input voltage is 1.5V, calculated from the maximum dropout voltage of 370mV (for VOUT < 2.5V) plus nominal output (1.2V). At 600mA load and –40°C, dropout may reach 600mV per datasheet limits, so 1.8V input is recommended for margin. Input must remain ≥2V per absolute maximum rating.
Can AP7365-12SNG-7 operate without an output capacitor?
No. The device requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability, as confirmed in the Application Information section. Omitting it causes oscillation and output voltage collapse under load. Larger values improve transient response but are not mandatory beyond the 1μF minimum.
Is the ADJ pin functional in AP7365-12SNG-7?
No. AP7365-12SNG-7 is a fixed-output variant; the ADJ pin is internally connected to GND and must remain unconnected in the circuit. External connection risks regulation error or damage. Pin 6 serves only as a mechanical placeholder in the U-DFN2020-6 package.
How does thermal shutdown behave during sustained overload?
When junction temperature reaches +145°C, the output disables; it re-enables automatically once temperature falls to +130°C due to 15°C hysteresis. Under continuous overload, this causes on/off cycling - observable as output voltage pulsing - which limits average power dissipation and prevents permanent damage.
