Product details
Overview
AP7365-20SNG-7 from Diodes Incorporated is a fixed-output 2.0V, 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 FPGA I/O power, battery-powered IoT sensors, and portable consumer electronics requiring stable low-voltage bias.
For engineers reviewing the AP7365-20SNG-7 datasheet, AP7365-20SNG-7 pinout, AP7365-20SNG-7 application, or AP7365-20SNG-7 equivalent, key selection criteria include output voltage accuracy (±2%), PSRR (65dB @ 1kHz), thermal resistance (132°C/W), compatibility with 1μF ceramic output capacitors, and EN pin logic thresholds (VIH = 1.4V, VIL = 0.4V).
Technical Context
The AP7365-20SNG-7 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA) and high PSRR (65dB @ 1kHz) without external compensation. Its bandgap reference (0.8V) and error amplifier regulate output precisely across -40°C to +85°C ambient range.
Enable functionality uses CMOS-compatible input thresholds (VIH ≥ 1.4V, VIL ≤ 0.4V), while built-in 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 2.0V ±2% over -40°C to +85°C - ensures stable core/I/O rail for low-power microcontrollers and sensors. |
| Max Output Current | 600mA continuous - supports moderate-power digital loads like FPGA I/O banks or wireless SoC peripherals. |
| Quiescent Current | 35μA typical - extends battery life in always-on sensor nodes and wearables with multi-year runtime requirements. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); 370mV max at 600mA (VOUT < 2.5V) - enables operation down to VIN = 2.3V for 2.0V output. |
| PSRR | 65dB @ 1kHz - suppresses switching noise from adjacent DC-DC converters in mixed-signal PCB layouts. |
| Start-Up Time | 200μs typical - allows rapid wake-up from deep sleep modes in energy-harvesting systems. |
| Thermal Resistance | θJA = 132°C/W (U-DFN2020-6) - requires minimal copper area for thermal relief in space-constrained designs. |
Pinout & Package
AP7365-20SNG-7 is housed in a 2.0mm × 2.0mm, 0.65mm height U-DFN2020-6 package with exposed thermal pad (pin 1–6 layout). The package supports reflow soldering and provides low thermal resistance (θJA = 132°C/W) on standard FR-4 boards with minimum recommended pad layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin for stability and noise rejection. |
| GND (Pin 2) | Ground reference | Primary return path for input/output currents; must connect directly to thermal pad and system ground plane. |
| EN (Pin 1) | Enable control input | Active-high logic interface (VIH ≥ 1.4V); tie to IN if always-on operation is required. |
| OUT (Pin 4) | Regulated output | Delivers 2.0V ±2%; stable with ≥1μF ceramic capacitor (ESR > 15mΩ) placed within 2mm of pin. |
| ADJ (Pin 6) | Reference feedback node | No connection in fixed-output variants; internally tied to 0.8V bandgap reference for 2.0V regulation. |
| NC (Pin 5) | No connection | Unbonded terminal; must remain floating - no routing or soldering permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA quiescent current enables >10-year battery life in coin-cell–powered IoT endpoints. |
| Fast transient response | Stable under 10mA ↔ 600mA load steps with <20mV undershoot/overshoot - critical for GSM/DSP burst-mode operation. |
| Single-capacitor stability | Guaranteed stable with 1μF ceramic output capacitor (ESR > 15mΩ) - eliminates need for bulk electrolytic or complex compensation. |
| 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 (5V) systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2002E/MB | 300mA output, 2.0V fixed, 1.6μA IQ - lower current, far lower quiescent current. | Suitable only for sub-300mA loads; insufficient for FPGA I/O or burst-mode radios. | Select when ultra-low IQ dominates over output current capability (e.g., passive RFID sensors). |
| Torex XC6210B202MR-G | 600mA output, 2.0V fixed, 45μA IQ, 250mV dropout - slightly higher IQ, lower dropout. | Compatible footprint not available; requires redesign of PCB layout and thermal pad. | Choose if lower dropout (250mV) is critical and board re-spin is acceptable for marginal VIN margin. |
Compared with MCP1700-2002E/MB and XC6210B202MR-G, AP7365-20SNG-7 uniquely balances 600mA drive, 35μA IQ, and U-DFN2020-6 thermal performance - making it optimal for space-constrained, battery-operated systems needing both current headroom and efficiency.

FAQ
What is the minimum input voltage required for AP7365-20SNG-7 to maintain 2.0V output at 600mA?
The minimum input voltage is 2.3V, derived from the 300mV dropout specification at 600mA (2.0V + 0.3V = 2.3V). Operation below this voltage results in unregulated output. Input must also stay within the absolute maximum rating of 6.5V and recommended range of 2V–6V.
Can AP7365-20SNG-7 operate without an output capacitor?
No. A minimum 1μF ceramic capacitor with ESR > 15mΩ is mandatory at the OUT pin for stability and transient response. Omitting it causes oscillation and potential device failure. The capacitor must be placed within 2mm of OUT and GND pins using short, wide traces.
Is the EN pin 5V-tolerant when used with a 5V microcontroller GPIO?
Yes. The EN pin accepts up to VIN + 0.3V per absolute maximum ratings, and VIN is rated to 6.5V. With VIN ≤ 6V, a 5V GPIO safely exceeds VIH (1.4V) while remaining within safe voltage limits - no level-shifting required.
Does AP7365-20SNG-7 require a minimum load current to maintain regulation?
No. The device remains stable and fully regulated with zero load current, as confirmed in the datasheet's "No Load Stability" section. This eliminates the need for bleed resistors and preserves battery life in intermittent-operation systems.
