Product details
Overview
AP7365-20ERG-13 from Diodes Incorporated is a 600mA fixed-output (2.0V) low-dropout linear regulator in SOT223-ER package, featuring 35μA quiescent current, 300mV dropout at full load, and integrated enable control, thermal shutdown, and current limiting-designed for FPGA I/O power and battery-powered portable electronics.
For engineers reviewing the AP7365-20ERG-13 datasheet, AP7365-20ERG-13 pinout, AP7365-20ERG-13 application, or AP7365-20ERG-13 equivalent, key selection criteria include dropout voltage under 600mA load, PSRR performance at 1kHz, EN logic thresholds, thermal resistance in SOT223-ER, and compatibility with 1μF ceramic output capacitance.
Technical Context
The AP7365-20ERG-13 implements a PMOS pass transistor architecture enabling low dropout and fast transient response. Its internal 0.8V bandgap reference feeds an error amplifier that regulates output by modulating gate drive to the pass element.
Enable functionality uses CMOS-compatible input thresholds (VIH ≥1.4V, VIL ≤0.4V), while protection circuitry 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 ambient |
| Max Output Current | 600mA continuous; limited to 1.4A during overload |
| Dropout Voltage | 300mV at 600mA load (VOUT ≥2.5V spec; actual 2.0V version measured ≤370mV) |
| Quiescent Current | 35μA typical at zero load; enables multi-day battery life in standby |
| PSRR | 65dB at 1kHz, supporting clean power for noise-sensitive analog/DSP circuits |
| Start-Up Time | 200μs from EN high to regulated output, suitable for dynamic power sequencing |
| Thermal Resistance | 142°C/W junction-to-ambient (SOT223-ER on FR-4, 1oz Cu) |
Pinout & Package
SOT223-ER package with exposed thermal pad (pin 3 = IN, pin 1 = GND, pin 2 = OUT); thermally enhanced for higher power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass to GND near pin for stability |
| GND (Pin 1) | Ground reference | Primary return path; connects to thermal pad for heat conduction |
| OUT (Pin 2) | Regulated output | Delivers stable 2.0V; must be bypassed with ≥1μF ceramic capacitor to GND |
| EN (Not present) | Enable control input | Not implemented in ER-package fixed-output variant; device operates continuously when powered |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 300mV at 600mA enables use with 2.3V input for 2.0V rail-critical for single-cell Li-ion systems |
| Ultra-low IQ | 35μA quiescent current minimizes no-load battery drain in always-on IoT sensors |
| Fast transient response | Stable under 10mA→600mA load steps without overshoot, supporting GSM/EDGE baseband burst modes |
| Thermal robustness | +145°C shutdown with +15°C hysteresis prevents latch-up during sustained overload in enclosed enclosures |
| Capacitor flexibility | Stable with 1μF ceramic output capacitor (ESR >15mΩ), reducing BOM count vs. electrolytic solutions |

FAQ
Does AP7365-20ERG-13 include an enable (EN) pin?
No. The ER-package variant of AP7365-20ERG-13 omits the EN pin-unlike SOT25 and U-DFN2020-6 versions-making it a permanently enabled regulator. This simplifies design for always-on applications but removes software-controlled power gating capability.
What is the minimum input voltage required for 2.0V output regulation at 600mA?
The minimum input voltage is 2.3V, derived from the 300mV dropout specification (2.0V + 0.3V). Electrical characteristics confirm stable regulation down to VIN = VOUT + 0.37V (2.37V) at 600mA per test data, with guaranteed operation above 2.0V input per absolute max ratings.
Can AP7365-20ERG-13 operate with a 0.47μF output capacitor?
No. The datasheet specifies stability requires ≥1μF ceramic output capacitance with ESR >15mΩ. Using 0.47μF risks oscillation or excessive undershoot during load transients, as confirmed by CESR vs. load current stability curves on page 8 of DS32260 Rev. 11-3.
Is AP7365-20ERG-13 qualified for automotive applications?
No. While Diodes offers AEC-Q100-qualified variants in other part families, AP7365-20ERG-13 is not automotive-grade. It is rated for industrial temperature range (-40°C to +85°C) and lacks PPAP documentation, IATF 16949 manufacturing certification, or AEC change control per notes in the datasheet.
