Product details

Overview

AP7365-25SNG-7 from Diodes Incorporated is a fixed-output 2.5V, 600mA low-dropout linear regulator in U-DFN2020-6 package, featuring 35μA quiescent current, 300mV dropout at full load, and fast 200μs startup. It integrates enable control, thermal shutdown, and current limiting, and is optimized for battery-powered portable electronics requiring stable low-voltage core or I/O rail regulation.

For engineers reviewing the AP7365-25SNG-7 datasheet, AP7365-25SNG-7 pinout, AP7365-25SNG-7 application, or AP7365-25SNG-7 equivalent, key selection criteria include dropout voltage at 600mA, PSRR performance at 1kHz, EN logic thresholds, thermal resistance (θ_JA = 132°C/W), and compatibility with 1μF ceramic output capacitors.

Technical Context

The AP7365-25SNG-7 implements a PMOS pass transistor architecture enabling ultra-low quiescent current and high PSRR (65dB @ 1kHz) without external compensation. Its internal 0.8V bandgap reference and error amplifier regulate output precisely across -40°C to +85°C ambient range.

Enable functionality uses TTL-compatible input thresholds (V_IH ≥ 1.4V, V_IL ≤ 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 2.5V ±2% over temperature and load ensures stable core supply for 2.5V FPGA I/O banks.
Max Output Current	600mA continuous delivery supports mid-power digital loads like DSP peripherals or sensor interfaces.
Dropout Voltage	300mV at 600mA enables operation from 2.8V input - critical for single-cell Li-ion or Li-poly systems.
Quiescent Current	35μA typical allows >1-year battery life in always-on IoT nodes with 200mAh coin cells.
PSRR	65dB at 1kHz suppresses switching noise from adjacent DC/DC converters feeding shared input rails.
Startup Time	200μs enables rapid wake-up from deep sleep in portable devices without voltage droop-induced resets.
Thermal Resistance	θ_JA = 132°C/W (U-DFN2020-6) permits 450mW dissipation at +85°C ambient before thermal shutdown.

Pinout & Package

AP7365-25SNG-7 is housed in a 2.0mm × 2.0mm, 0.65mm height, thermally enhanced U-DFN2020-6 package with exposed thermal pad (pin 1–6 layout). The package supports high-density PCB layouts and efficient heat transfer via soldered thermal pad connection to internal ground plane.

Pin/Terminal	Circuit Role	Design Meaning
IN (Pin 3)	Input voltage supply	Accepts 2V–6V input; requires ≥1μF ceramic bypass capacitor placed adjacent to pin for stability and noise rejection.
GND (Pin 2)	Ground reference	Common return path for input/output capacitors and thermal pad; must connect directly to PCB ground plane.
EN (Pin 1)	Enable control input	Active-high logic interface; drives regulator ON when ≥1.4V, OFF when ≤0.4V; tie to IN if always-on operation required.
OUT (Pin 4)	Regulated output	Delivers fixed 2.5V; requires ≥1μF ceramic capacitor with ESR >15mΩ placed within 2mm of pin for transient stability.
ADJ (Pin 6)	Reference feedback node	No-connect in fixed-output variants; internally tied to 0.8V reference; must remain unconnected and un-bypassed.
NC (Pin 5)	No connection	Internally unused; electrically isolated; may be left floating or connected to GND per layout convenience.

Key Features

Feature	Design Value
Ultra-low IQ operation	35μA quiescent current minimizes standby power loss in battery-backed real-time clocks and memory retention circuits.
Fast transient response	Stable under 10mA–600mA load steps with <20mV undershoot/overshoot - essential for GSM/TDMA baseband power rails.
Low-ESR capacitor support	Stable with 1μF ceramic output capacitor (ESR >15mΩ), eliminating need for larger, higher-cost tantalum or aluminum electrolytics.
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 accommodates single-cell Li-ion (2.7–4.2V), USB-powered (4.75–5.25V), and multi-cell alkaline inputs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-quiescent-current LDO applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP7361-25SNG-7	Lower 300mA rating, identical 2.5V fixed output, same U-DFN2020-6 package and 35μA IQ.	Suitable only for sub-300mA loads; insufficient for FPGA I/O or dual-radio systems.	Select when load current is confirmed ≤300mA and cost reduction is prioritized over headroom.
MCP1700T-2502E/MB	3.3V max input, 250mA output, 1.6μA IQ, SOT23-5 package; lacks EN pin and thermal shutdown.	Only viable for ultra-low-power sensors with strict <250mA demand and no fault protection requirements.	Choose only for niche ultra-low-IQ applications where input voltage never exceeds 3.3V and protection is handled externally.

Compared with AP7365-25SNG-7, AP7361-25SNG-7 trades 300mA current capability for lower cost in identical footprint, while MCP1700T-2502E/MB sacrifices robustness (no EN, no thermal shutdown) to achieve nanoamp-level standby - making AP7365-25SNG-7 the balanced choice for production-grade portable electronics requiring reliability, headroom, and integration.

FAQ

What is the minimum input voltage required for AP7365-25SNG-7 to maintain regulation at 600mA?

The minimum input voltage is calculated as V_OUT + V_DROPOUT = 2.5V + 0.3V = 2.8V. At 600mA load and +25°C, dropout is typically 300mV; worst-case (600mV per datasheet) raises minimum to 3.1V. Input below 2.8V causes output collapse, and operation below 2.0V absolute rating risks damage.

Can AP7365-25SNG-7 operate without an output capacitor?

No. The device requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability. Omitting it causes oscillation and voltage overshoot during load transients. Larger capacitance improves line/load regulation but does not eliminate the fundamental need for the capacitor.

Is the ADJ pin used in the AP7365-25SNG-7 variant?

No. AP7365-25SNG-7 is a fixed 2.5V output version; the ADJ pin (Pin 6) is internally connected to the 0.8V reference and must remain unconnected. Routing or bypassing this pin introduces instability and violates the fixed-output configuration.

How does thermal performance differ between U-DFN2020-6 and SOT25 packages?

U-DFN2020-6 has θ_JA = 132°C/W versus SOT25's 169°C/W - a 22% improvement in junction-to-ambient thermal resistance. This allows ~150mW higher power dissipation before thermal shutdown at +85°C ambient, making the U-DFN2020-6 preferred for higher-current or higher-temperature deployments.
