Product details

Overview

AP7365-15SNG-7 from Diodes Incorporated is a fixed-output 1.5V, 600mA low-dropout linear regulator with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It operates from 2V to 6V input, delivers ±2% output accuracy across –40°C to +85°C, and stabilizes with a single 1μF ceramic output capacitor - ideal for FPGA I/O rail and battery-powered portable electronics.

For engineers reviewing the AP7365-15SNG-7 datasheet, AP7365-15SNG-7 pinout, AP7365-15SNG-7 application, or AP7365-15SNG-7 equivalent, key selection criteria include low-I_Q operation under light load, fast 200μs start-up for dynamic power sequencing, PSRR of 65dB at 1kHz, and thermal shutdown at +145°C with 15°C hysteresis.

Technical Context

The AP7365-15SNG-7 integrates a PMOS pass element, bandgap reference, error amplifier, and protection circuitry (current limit, thermal shutdown) in a U-DFN2020-6 package with exposed thermal pad. Its fixed 1.5V output eliminates external feedback resistors, simplifying layout while maintaining stability with low-ESR ceramic capacitors.

It features active-high EN control with VIH ≥ 1.4V and VIL ≤ 0.4V, enabling direct interface with 1.8V/3.3V logic. The device achieves fast transient response via optimized internal compensation, delivering <20mV undershoot/overshoot during 10mA–600mA load steps at 1.5V output.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.5V ±2% over –40°C to +85°C - ensures stable core voltage for low-voltage logic and memory interfaces.
Max Output Current	600mA continuous - supports moderate-power FPGA I/O banks or microcontroller peripherals without external boost.
Quiescent Current	35μA typical - extends battery life in always-on sensor nodes and standby modes of portable devices.
Dropout Voltage	300mV at 600mA (V_OUT ≥ 2.5V), 370mV max at 1.5V - enables operation down to 1.8V input, critical for single-cell Li-ion systems.
PSRR	65dB at 1kHz - suppresses switching noise from adjacent DC-DC converters feeding mixed-signal SoCs.
Start-Up Time	200μs - allows rapid power cycling in real-time DSP wake/sleep sequences without timing penalty.
Thermal Shutdown	+145°C threshold with +15°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design.

Pinout & Package

AP7365-15SNG-7 uses the U-DFN2020-6 (SN) package: 2.0mm × 2.0mm, 0.5mm pitch, with exposed thermal pad (pin 4 = GND). Pin 1 is marked by chamfered corner.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Input voltage supply	Accepts 2V–6V; requires ≥1μF ceramic bypass to GND close to pin for noise immunity and stability.
2 (GND)	Ground reference	Common return path for IN, OUT, EN, and thermal pad; must be low-impedance plane for thermal dissipation.
3 (EN)	Enable control input	Active-high logic: drives output ON when ≥1.4V; ties to IN if always-on operation required.
4 (GND)	Thermal pad / ground	Exposed copper pad soldered to PCB ground plane; essential for thermal resistance of 132°C/W (J-A).
5 (ADJ/NC)	No connection (fixed version)	Internally tied off; must remain unconnected - no external components required for 1.5V output.
6 (OUT)	Regulated output	Delivers 1.5V ±2%; requires ≥1μF ceramic capacitor to GND within 2mm for transient stability.

Key Features

Feature	Design Value
Ultra-low quiescent current	35μA typical enables >1-year battery life in coin-cell-powered IoT sensors with 10μA average load.
Fast transient response	Stable 1.5V output under 10mA→600mA load steps with <20mV deviation - meets GSM/TDMA baseband power requirements.
Low-ESR capacitor compatibility	Stable with 1μF ceramic output capacitor (ESR >15mΩ) - eliminates need for costly tantalum or polymer caps.
Integrated protection	Current limit (~1.4A), short-circuit clamp (~240mA), and thermal shutdown prevent field failures in unregulated input environments.
Wide input range	2V–6V operation supports single-cell Li-ion (2.7–4.2V), USB-powered (5V), and dual-cell alkaline (up to 3.2V) systems.

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
MCP1700-1502E/MB	300mA max output, 1.8μA I_Q, SOT23-5 package - lower current, lower I_Q, but higher dropout (600mV @ 250mA).	Suitable only for sub-300mA loads; insufficient for FPGA I/O or multi-sensor hubs requiring >400mA peak.	Select when ultra-low I_Q dominates over current capability and board space permits larger dropout margin.
Torex XC6210B152MR-G	600mA, 25μA I_Q, 250mV dropout @ 1.5V - slightly lower I_Q and dropout, but only available in SOT25 and USP-6B packages.	Lacks U-DFN2020-6 footprint; requires PCB redesign; no EN pin in standard variant - limits power sequencing flexibility.	Choose only if 25μA I_Q is mandatory and SOT25 layout is acceptable; otherwise AP7365-15SNG-7 offers superior integration.

Compared with MCP1700-1502E/MB and XC6210B152MR-G, AP7365-15SNG-7 uniquely balances 600mA drive, 35μA I_Q, 300mV dropout, EN control, and U-DFN2020-6 compactness - making it optimal for space-constrained, battery-powered systems needing robust transient performance without sacrificing efficiency.

FAQ

What is the minimum input voltage required for AP7365-15SNG-7 to regulate 1.5V output at 600mA?

The minimum input voltage is 1.8V, calculated from the 300mV dropout specification at 600mA load. At ambient temperatures up to +85°C, the dropout may increase to 370mV, requiring VIN ≥ 1.87V for guaranteed regulation. Operation below 2.0V input is not recommended per absolute maximum ratings.

Can AP7365-15SNG-7 operate without an output capacitor?

No. A minimum 1μF ceramic capacitor with ESR >15mΩ is required between OUT and GND for stability and transient response. Omitting it causes oscillation and output voltage collapse under load. Larger values (e.g., 4.7μF) further improve line/load transient suppression but are not mandatory.

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 to ≥1.4V for enable or ≤0.4V for disable. If unused, tie EN directly to IN to ensure always-on operation; floating EN may cause erratic output behavior due to noise susceptibility.

How does thermal shutdown behave during sustained overload?

When junction temperature reaches +145°C, the output disables and remains off until temperature drops to +130°C (15°C hysteresis). Under continuous overload, this causes thermal cycling - visible as periodic output toggling. To avoid this, ensure θ_JA ≤ 132°C/W via adequate PCB copper area under the thermal pad.
