Product details
Overview
AP7365-28YRG-13 from Diodes Incorporated is a fixed-output 2.8V, 600mA low-dropout linear regulator in SOT89-3 package with enable control, 35μA quiescent current, 300mV dropout at full load, and ±2% output voltage accuracy across –40°C to +85°C. It powers FPGA I/O rails and battery-backed microcontroller peripherals where fast transient response and ultra-low standby power are critical.
For engineers reviewing the AP7365-28YRG-13 datasheet, AP7365-28YRG-13 pinout, AP7365-28YRG-13 application, or AP7365-28YRG-13 equivalent, key selection criteria include dropout voltage at 600mA, EN logic thresholds (VIH ≥ 1.4V, VIL ≤ 0.4V), thermal shutdown threshold (+145°C), PSRR (65dB @ 1kHz), and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7365-28YRG-13 implements a PMOS pass transistor architecture enabling low dropout and high PSRR. 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 logic with hysteresis-free thresholds; thermal shutdown activates at +145°C junction temperature and recovers at +130°C. Current limiting clamps output to ~1.4A during overload, while short-circuit protection limits current to ~240mA when VOUT drops below 25% of nominal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% over –40°C to +85°C; enables direct replacement of 2.8V logic supply rails without external resistors. |
| Max Output Current | 600mA continuous; supports single-rail powering of mid-power FPGA I/O banks or sensor signal chains. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); allows operation from 3.1V input (e.g., single Li-ion cell post-LDO) while maintaining regulation. |
| Quiescent Current | 35μA typical at zero load; extends battery life in always-on IoT edge nodes with infrequent wake cycles. |
| PSRR | 65dB at 1kHz; suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Start-Up Time | 200μs from EN high to regulated 2.8V; meets real-time wake-up timing for DSP subsystems in portable devices. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT89-3 (YR package) with exposed thermal pad on underside; requires minimum 1oz copper thermal land (≥ 10mm²) for reliable 600mA operation at +85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; must be bypassed with ≥1μF MLCC placed adjacent to pin to suppress high-frequency noise and ensure stability. |
| GND (Pin 1) | Power ground reference | Low-impedance return path for input/output currents; connects directly to thermal pad for heat dissipation. |
| OUT (Pin 2) | Regulated output | Delivers stable 2.8V; requires ≥1μF ceramic capacitor to GND within 2mm for optimal transient response and ESR-based stability. |
| EN (Not present) | Enable control input | Not implemented in YR-package fixed-output variant; device operates continuously when powered - no external enable required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA quiescent current enables >1-year battery life in coin-cell-powered sensors with 10s wake intervals. |
| Fast transient response | Stabilizes within 50μs after 10mA→600mA load step; prevents brownout in GSM/TDMA baseband circuits with pulsed RF transmit bursts. |
| Low-ESR capacitor support | Stable with 1μF ceramic output capacitor (ESR ≥15mΩ); eliminates need for costly tantalum or polymer caps in space-constrained designs. |
| Integrated protection | Combines current limit (~1.4A), short-circuit clamp (~240mA), and thermal shutdown (+145°C) to eliminate external fault management circuitry. |
| Wide input range | Operates from 2V to 6V input; compatible with single-cell Li-ion (2.7–4.2V), USB (4.75–5.25V), and industrial 5V rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-2802E/MB | 300mA max output, 2μA IQ, SOT89-3 package; lacks current limit and thermal shutdown. | Suitable only for <300mA loads with external fault protection; not recommended for unattended battery systems. | Select if ultra-low IQ dominates over output current and protection needs. |
| TPS7A2028PDQNR | 300mA max, 6.5μA IQ, WSON-6 package; includes enable pin and thermal shutdown but no current limit. | Requires external current sense for overload protection; smaller footprint but lower thermal mass than SOT89. | Select for space-constrained designs where 300mA suffices and board area is premium. |

FAQ
Is AP7365-28YRG-13 pin-compatible with other SOT89-3 LDOs?
No. While the SOT89-3 footprint matches standard 3-pin variants, AP7365-28YRG-13 has IN/GND/OUT pinout (3/1/2), whereas many competitors use IN/OUT/GND or OUT/GND/IN arrangements. PCB layout must follow Diodes' specified top view: Pin 3 = IN, Pin 1 = GND, Pin 2 = OUT.
Can AP7365-28YRG-13 operate without an output capacitor?
No. The datasheet mandates a minimum 1μF ceramic capacitor from OUT to GND for stability and transient performance. Omitting it causes oscillation and voltage overshoot during load steps. The capacitor must be placed within 2mm of the OUT and GND pins using short, wide traces.
What is the maximum allowable power dissipation for AP7365-28YRG-13 at +85°C ambient?
With θJA = 133°C/W (SOT89-YR), maximum power dissipation is 0.52W at TA = +85°C, calculated as (145°C − 85°C)/133°C/W. At VIN = 5.0V and VOUT = 2.8V, this limits continuous output current to ~236mA unless enhanced PCB copper area reduces effective θJA.
Does AP7365-28YRG-13 require a minimum load current to maintain regulation?
No. The device remains stable and fully regulated at zero load current. This eliminates the need for wasteful bleed resistors in battery-powered applications, preserving standby efficiency and extending operational lifetime.
