Product details
Overview
AP7365-20YG-13 from Diodes Incorporated is a fixed-output 2.0V, 600mA low-dropout linear regulator in SOT89 package with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable power to FPGA I/O rails and battery-powered consumer electronics where low standby power and fast transient response are critical.
For engineers reviewing the AP7365-20YG-13 datasheet, AP7365-20YG-13 pinout, AP7365-20YG-13 application, or AP7365-20YG-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 AP7365-20YG-13 implements a PMOS pass transistor architecture enabling ultra-low quiescent current (35μA typ.) while maintaining fast transient response-settling within 200μs after enable assertion. Its internal 0.8V bandgap reference and error amplifier regulate output precisely across -40°C to +85°C ambient.
It integrates current limit (1.4A typ.), short-circuit protection (240mA), and thermal shutdown (+145°C with 15°C hysteresis). The device operates from 2V to 6V input and sustains regulation with no minimum load, supporting both always-on and enable-controlled power domains.
Key Specifications

Pinout & Package
SOT89-3 (Y Package) thermally enhanced plastic package with exposed tab connected to GND; footprint optimized for PCB heat dissipation and low-inductance layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output voltage node | Must be bypassed with ≥1μF ceramic capacitor placed adjacent to pin; connects to load and feedback path in adjustable versions |
| 2 (GND) | Power and signal reference ground | Low-impedance return path; ties to thermal pad (TAB) for heat conduction and EMI reduction |
| 3 (IN) | Unregulated input supply input | Requires ≥1μF MLCC decoupling to GND; voltage range 2V–6V; feeds internal pass element and bias circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Enable control with logic-compatible thresholds | VIH = 1.4V min., VIL = 0.4V max.; allows direct interface with 1.8V/3.3V GPIO without level shifters |
| Stability with minimal output capacitance | Guaranteed stable with 1μF ceramic capacitor (ESR > 15mΩ); reduces BOM count and board area |
| Fast load transient response | Settles within ±20mV for 10mA ↔ 600mA step at 3.3V output; prevents DSP/FPGA brownouts during burst activity |
| Robust fault protection | Combined current limit, short-circuit clamp (240mA), and thermal shutdown prevent damage under sustained overload |
| Wide operating temperature range | -40°C to +85°C ambient; validated for industrial and extended-temperature consumer applications |

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/TO | 300mA max output; 2.0V fixed; 1.6μA IQ; SOT23-3 package | Limited to ultra-low-current loads; insufficient for 600mA FPGA I/O rails | Select only for sub-100mA sensor nodes where IQ < 2μA is mandatory |
| TLS850B2TE/V1 | Automotive-grade (AEC-Q100); 500mA; 2.0V fixed; 45μA IQ; TO-252 | Higher thermal resistance (θJA = 60°C/W); requires larger PCB copper area | Choose for automotive body electronics needing PPAP support; not cost-optimized for consumer designs |
Compared with MCP1700-2002E/TO and TLS850B2TE/V1, the AP7365-20YG-13 uniquely balances 600mA capability, 35μA IQ, SOT89 thermal performance, and 1μF ceramic stability-making it optimal for space-constrained industrial and portable designs requiring robust mid-current regulation without automotive qualification overhead.

FAQ
What is the maximum input voltage for AP7365-20YG-13?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2.0V to 6.0V. Operation above 6.0V risks exceeding thermal limits under load, especially in SOT89 without extended copper pour. At VIN = 6.0V and IOUT = 600mA, power dissipation reaches 2.4W-requiring careful thermal design per θJA = 133°C/W.
Can AP7365-20YG-13 operate without an output capacitor?
No. A minimum 1μF ceramic capacitor with ESR > 15mΩ is required on the OUT pin for stability. Omitting it causes oscillation and unregulated output. The capacitor must be placed directly between OUT and GND, adjacent to the SOT89 pins, with short, wide traces to minimize inductance.
Is the EN pin internally pulled up or down?
The EN pin has no internal pull-up or pull-down resistor. It must be actively driven: connect to IN for always-on operation, or to a GPIO with VIH ≥ 1.4V and VIL ≤ 0.4V. Leaving EN floating may cause erratic turn-on due to noise coupling, especially in high-EMI environments.
Does AP7365-20YG-13 support adjustable output voltages?
No. AP7365-20YG-13 is a fixed 2.0V output variant in SOT89 package. Adjustable versions (e.g., AP7365-ADJ) exist only in SOT25 and U-DFN2020-6 packages and require external resistors on the ADJ pin. This part lacks the ADJ pin and is functionally hardwired for 2.0V.
