Product details
Overview
AP7365-12YG-13 from Diodes Incorporated is a fixed-output 1.2V, 600mA low-dropout linear regulator in SOT89 package with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable core voltage for FPGA I/O rails and portable microcontroller subsystems operating from 2V–6V input sources.
For engineers reviewing the AP7365-12YG-13 datasheet, AP7365-12YG-13 pinout, AP7365-12YG-13 application, or AP7365-12YG-13 equivalent, this page provides verified electrical parameters, thermal behavior, EN-controlled startup timing, and real-world transient response data for battery-powered and space-constrained designs.
Technical Context
The AP7365-12YG-13 implements a PMOS pass transistor architecture enabling ultra-low dropout (300mV @ 600mA) and fast transient recovery (<100μs load step). Its internal 0.8V bandgap reference and error amplifier support ±2% output accuracy across –40°C to +85°C ambient.
Enable logic operates with VIH ≥ 1.4V and VIL ≤ 0.4V, allowing direct interfacing with 1.8V/3.3V GPIO. Built-in thermal shutdown activates at +145°C with +15°C hysteresis, and current limit clamps output to 1.4A during overload-distinct from short-circuit protection (240mA clamp).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±2% over –40°C to +85°C; enables precise core biasing for low-voltage logic. |
| Max Output Current | 600mA continuous; supports single-rail power for mid-power FPGA I/O banks or MCU peripherals. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V), 370mV at 600mA (VOUT < 2.5V); allows operation down to VIN = 1.5V for 1.2V output. |
| Quiescent Current | 35μA typical at zero load; extends battery runtime in always-on sensor nodes and standby modes. |
| 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 VOUT; enables rapid wake-up in duty-cycled applications like GSM baseband. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis; prevents permanent damage during sustained overload. |
Pinout & Package
SOT89-3 (Y package) with exposed thermal tab on pin 3 (IN), providing 133°C/W junction-to-ambient thermal resistance under standard FR-4 layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output node | Delivers 1.2V to load; requires ≥1μF ceramic capacitor placed adjacent to pin for stability and transient suppression. |
| 2 - GND | Power ground reference | Low-impedance return path for load current and internal bias; must connect directly to thermal pad and system ground plane. |
| 3 - IN | Input voltage supply | Accepts 2V–6V input; bypassed with ≥1μF MLCC close to pin to suppress ripple and EMI from upstream converters. |
Key Features
| Feature | Design Value |
|---|---|
| Low IQ with EN control | 35μA quiescent current active, 0.1μA shutdown current-enables microamp-level system sleep states. |
| Fast transient response | Stable under 10mA→600mA load steps with <20mV undershoot/overshoot; critical for DSP burst-mode operation. |
| Stable with 1μF ceramic output cap | No minimum ESR requirement; eliminates need for bulk tantalum or aluminum electrolytic capacitors. |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) prevent field failures without external circuitry. |
| Wide input range | 2V–6V operation supports single-cell Li-ion (3.0–4.2V), dual-cell alkaline (2.4–3.2V), and USB-powered systems. |
Applications
| Portable Medical Sensors | FPGA I/O Power 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 |
|---|---|---|---|
| MCP1700T-1202E/TT | 300mA max output, 2.5μA IQ, SOT23-5 package; no enable pin, higher dropout (600mV @ 250mA) | Limited to ultra-low-power sensors; insufficient for 600mA FPGA I/O loads | Select only when IQ < 5μA is mandatory and load current ≤300mA. |
| TPS7A0512PDBVR | 200mA max output, 25μA IQ, 170mV dropout @ 200mA; integrated thermal foldback, no short-circuit clamp | Not suitable for high-current burst loads; lacks robust fault protection for automotive environments | Prefer for sub-200mA always-on IoT nodes where minimal footprint outweighs current capability. |
Compared with MCP1700T-1202E/TT and TPS7A0512PDBVR, the AP7365-12YG-13 uniquely balances 600mA drive, 35μA IQ, and comprehensive fault protection in a thermally enhanced SOT89 package-making it optimal for mid-power portable and automotive body electronics where reliability and headroom matter.

FAQ
What is the maximum input voltage for AP7365-12YG-13?
The absolute maximum input voltage is 6.5V, but recommended operating range is 2V to 6V. Exceeding 6V risks permanent damage to the internal pass transistor and bandgap reference. For 1.2V output, minimum functional input is 1.5V due to 300mV dropout specification.
Can AP7365-12YG-13 operate without an output capacitor?
No. A minimum 1μF ceramic capacitor is required between OUT and GND for stability and transient performance. Omitting it causes oscillation and voltage overshoot during load steps. The device is not stable with zero output capacitance, per datasheet Section 8.2.
How does thermal shutdown behave under sustained overload?
When junction temperature reaches +145°C, the output disables; it re-enables once temperature drops to +130°C. Under continuous overload, this creates on/off cycling-visible as intermittent VOUT collapse. PCB thermal design (copper area, via count) must keep θJA below 133°C/W to avoid cycling at 600mA.
Is AP7365-12YG-13 qualified for automotive use?
AP7365-12YG-13 itself is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7365-12YG-13Q) with PPAP documentation, IATF 16949 manufacturing, and extended testing-but this specific part number is commercial grade (-40°C to +85°C ambient, no automotive qualification).
