Product details
Overview
AP7361-10FGE-7 from Diodes Incorporated is a 1A fixed-output (1.0V) ultra-low dropout linear regulator in U-DFN3030-8 package, featuring 70µA typical quiescent current, 500mV dropout at 1A load, and integrated enable control. It delivers stable low-voltage power for FPGA I/O rails, battery-powered audio subsystems, and laptop core logic where tight regulation and fast transient response are critical.
For engineers reviewing the AP7361-10FGE-7 datasheet, AP7361-10FGE-7 pinout, AP7361-10FGE-7 application, or AP7361-10FGE-7 equivalent, key selection criteria include dropout voltage at full load, thermal resistance (θJA = 70°C/W), EN pin logic thresholds (VIL ≤ 0.3V, VIH ≥ 1.0V), and compatibility with ≥2.2µF ceramic output capacitors.
Technical Context
The AP7361-10FGE-7 implements a PMOS pass transistor architecture with internal 0.8V bandgap reference and error amplifier, enabling precise 1.0V output regulation across -40°C to +85°C ambient. Its fixed-output configuration eliminates external resistor divider requirements while retaining EN-controlled on/off functionality.
Protection circuitry includes foldback current limiting (1.1–1.5A trip), thermal shutdown at ~150°C with 20°C hysteresis, and short-circuit current clamping to 200mA. The device achieves 65dB PSRR at 1kHz and maintains stability with ceramic output capacitors ≥2.2µF and ESR between 10mΩ and 300mΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±1% at 100mA, ±2% over full temperature range - ensures reliable operation of 1.0V FPGA I/O banks. |
| Dropout Voltage | 500mV at 1A load - enables operation from 1.5V input, critical for single-cell Li-ion or boosted 1.2V supply rails. |
| Quiescent Current | 70µA typical - 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 sensitive analog or RF circuitry. |
| Thermal Resistance | θJA = 70°C/W (U-DFN3030-8) - supports 1A continuous output at +85°C ambient with minimal PCB copper area. |
| Enable Threshold | VIH ≥ 1.0V, VIL ≤ 0.3V - compatible with 1.8V/3.3V GPIO without level-shifting in portable SoC designs. |
| Output Capacitor | Stable with ≥2.2µF ceramic (10–300mΩ ESR) - reduces BOM count vs. tantalum and avoids aging-related drift. |
Pinout & Package
AP7361-10FGE-7 uses the U-DFN3030-8 (3.0mm × 3.0mm, 0.5mm pitch) thermally enhanced package with exposed thermal pad. Pin 1 is IN; Pin 2 is GND; Pin 3 is ADJ/NC (no connection in fixed-output variant); Pin 4 is GND; Pin 5 is EN; Pin 6 is NC; Pin 7 is NC; Pin 8 is IN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 1, 8) | Input power supply connection | Dual-input pins reduce trace inductance and improve high-frequency noise rejection; requires ≥1µF ceramic bypass to GND. |
| GND (Pins 2, 4) | Power ground reference | Dual GND pins lower ground impedance and minimize voltage offset under dynamic load, critical for <1% output accuracy. |
| EN (Pin 5) | Active-high enable control | Directly driven by microcontroller GPIO; pulls low to disable regulator and reduce IQ to 0.05µA, extending battery life. |
| OUT (Pin 1) | Regulated 1.0V output | Single-output pin routed to load; requires ≥2.2µF ceramic capacitor placed adjacent to OUT/GND for transient stability. |
| ADJ/NC (Pin 3) | Adjust pin / no connection | Internally tied off in fixed-output version; must remain unconnected - floating or biased connections risk regulation instability. |
| NC (Pins 6, 7) | No connection | Electrically isolated; PCB pads may be used for thermal relief but must not be connected to any net. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 500mV at 1A enables use with 1.5V input sources - essential for energy harvesting and single-cell battery systems. |
| Low quiescent current | 70µA typical allows >1-year battery life in always-on IoT sensors powered by CR2032 cells. |
| Fast start-up time | 200µs typical enables rapid power sequencing in multi-rail processors without external delay circuits. |
| Ceramic capacitor stability | Validated with 2.2µF–10µF X5R/X7R ceramics - eliminates need for costly tantalum or polymer capacitors. |
| Integrated protection | Current limit (1.1–1.5A), thermal shutdown (150°C), and short-circuit clamp (200mA) prevent field failures without external components. |

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-1002E/MB | 1A output, 600mV dropout at 1A, 2.5µA IQ, SOT-23-5 package | Lower IQ but higher dropout; limited thermal performance (θJA ≈ 200°C/W) restricts 1A operation to low ambient temps | Select when ultra-low standby power dominates over full-load efficiency and thermal headroom. |
| Torex XC6210B102MR-G | 1A output, 350mV dropout at 1A, 90µA IQ, SOT-25 package | Lower dropout but higher IQ and smaller package limits power dissipation; no enable pin | Select when board space is constrained and enable control is unnecessary for the power architecture. |
Compared with MCP1703T-1002E/MB and XC6210B102MR-G, AP7361-10FGE-7 uniquely balances 500mV dropout, 70µA IQ, and 70°C/W thermal resistance in a 3×3mm DFN - making it optimal for thermally dense, battery-sensitive 1.0V applications requiring enable control.

FAQ
What is the minimum input voltage required for AP7361-10FGE-7 to regulate 1.0V output at 1A?
The absolute minimum input is 1.5V, calculated from 1.0V output plus 500mV typical dropout. However, the recommended operating range starts at 2.2V per datasheet specifications to guarantee performance across temperature and process variations. Below 2.2V, line regulation and PSRR degrade significantly.
Can AP7361-10FGE-7 be used without an enable signal?
Yes - tie the EN pin directly to the IN supply rail to maintain permanent operation. This configuration draws 70µA quiescent current continuously. Do not leave EN floating, as leakage or noise could cause erratic on/off cycling and output instability.
Is the U-DFN3030-8 package lead-free and RoHS compliant?
Yes - AP7361-10FGE-7 is fully RoHS 2 compliant (2011/65/EU), halogen- and antimony-free ("Green"), with <900ppm bromine, <900ppm chlorine, and <1000ppm antimony. No lead is purposely added, meeting EU Directive 2002/95/EC requirements.
What is the maximum allowable output capacitance for stability?
No upper limit exists - the AP7361-10FGE-7 remains stable with output capacitance up to 100µF. Larger values (e.g., 10–47µF) improve load transient response and reduce output ripple, provided the capacitor's ESR stays within 10–300mΩ and voltage rating exceeds 1.0V by ≥50%.
