Product details
Overview
AP7365-33YRG-13 from Diodes Incorporated is a fixed-output 3.3V, 600mA low-dropout linear regulator in SOT89-3 package with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable power to FPGA I/O rails, notebook subsystems, and battery-powered consumer electronics requiring fast transient response and ultra-low standby consumption.
For engineers reviewing the AP7365-33YRG-13 datasheet, AP7365-33YRG-13 pinout, AP7365-33YRG-13 application, or AP7365-33YRG-13 equivalent, key selection criteria include dropout voltage at 600mA, PSRR at 1kHz, thermal shutdown threshold, EN logic thresholds, and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7365-33YRG-13 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA) and high PSRR (65dB @ 1kHz). Its internal 0.8V bandgap reference and error amplifier regulate output precisely across -40°C to +85°C ambient.
Enable functionality uses TTL-compatible thresholds (VIH ≥ 1.4V, VIL ≤ 0.4V), while protection circuitry includes foldback current limiting (1.4A typical), short-circuit clamping (240mA), and thermal shutdown at +145°C with +15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% over -40°C to +85°C and 0–600mA load |
| Max Output Current | 600mA continuous; internal current limit protects against overload |
| Dropout Voltage | 300mV at 600mA (ensures regulation down to VIN = 3.6V) |
| Quiescent Current | 35μA typical (enables >1-year battery life in always-on IoT sensors) |
| PSRR | 65dB at 1kHz (suppresses switching noise from upstream DC/DC converters) |
| Start-Up Time | 200μs (supports rapid wake-up from deep sleep in portable devices) |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis |
Pinout & Package
SOT89-3 (YR package) with exposed thermal pad on pin 3 (GND); compact 4.5mm × 2.5mm footprint optimized for thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2V–6V; requires ≥1μF MLCC bypass to GND for stability |
| OUT (Pin 2) | Regulated output | Delivers fixed 3.3V; stable with ≥1μF ceramic capacitor (ESR >15mΩ) |
| GND (Pin 3, Tab) | Ground reference & thermal path | Primary thermal dissipation path; must be connected to large copper pour |
| EN (Not present) | Enable control input | Not implemented in YR-package fixed-output variant; permanently enabled |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 300mV at 600mA enables use with single-cell Li-ion (3.0V min) or 3.3V system rails |
| Ultra-low IQ | 35μA quiescent current minimizes battery drain in standby mode |
| Fast transient response | Stable under 10mA→600mA load steps without overshoot; critical for DSP/FPGA core sequencing |
| Integrated protection | Current limit, short-circuit clamp, and thermal shutdown prevent field failures |
| Small-footprint packaging | SOT89-3 (YR) offers 4.5×2.5mm body with thermal pad for >133°C/W θJA |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3302E/TO | 300mA max output, 2μA IQ, SOT23-3 package, no thermal pad | Limited to ultra-low-power microcontrollers; insufficient for 600mA FPGA I/O loads | Select only when load current <300mA and thermal constraints allow smaller package |
| TPS7A2033PDBVR | 300mA, 6.5μA IQ, 175mV dropout @ 300mA, WSON-6 with thermal pad | Lower dropout but halved current capacity; higher cost per mA | Prefer for battery-critical designs where 300mA suffices and PCB area is constrained |
Compared with MCP1700-3302E/TO and TPS7A2033PDBVR, the AP7365-33YRG-13 uniquely balances 600mA delivery, 35μA IQ, and SOT89 thermal performance-making it optimal for mid-power portable and industrial applications where both current headroom and efficiency matter.

FAQ
What is the minimum input voltage required for AP7365-33YRG-13 to maintain regulation?
The AP7365-33YRG-13 requires VIN ≥ VOUT + VDROPOUT = 3.3V + 0.3V = 3.6V to sustain 600mA output current. At lighter loads, dropout decreases - e.g., 150mV at 100mA - allowing operation down to ~3.45V. Below 2.0V input, the device ceases regulation entirely per absolute maximum ratings.
Can AP7365-33YRG-13 operate without an external output capacitor?
No. The AP7365-33YRG-13 requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability, as confirmed in the datasheet's "Output Capacitor" section. Omitting it risks oscillation, poor transient response, and potential thermal runaway under load.
Is the EN pin functional on the AP7365-33YRG-13 package?
No. The YR suffix denotes the SOT89-3 fixed-output variant, which omits the EN pin. Pin configuration is strictly IN–OUT–GND (Tab). Enable functionality is only available in SOT25 and U-DFN2020-6 packages (e.g., AP7365-33WG-7 or AP7365-33SNG-7).
How does thermal performance differ between AP7365-33YRG-13 and the SOT223 version?
The AP7365-33YRG-13 (SOT89-3) has θJA = 133°C/W, while the SOT223 (ER/EV) achieves 142°C/W per datasheet. Though SOT89's lower θJA suggests better cooling, its smaller thermal pad area limits absolute power dissipation versus SOT223's larger tab. For >1W dissipation, SOT223 remains preferable despite marginally higher θJA.
