Product details
Overview
AP7380-44W5-7 from Diodes Incorporated is a fixed-output 4.4V ultra-low dropout (ULDO) linear regulator IC designed for space-constrained portable and battery-powered systems. It delivers up to 150mA output current with 500mV dropout at 50mA, ±1% output voltage accuracy, 1.8–3.0µA ground current, and operates across a 3.5–24V input range - enabling direct regulation from 12V rails or multi-cell batteries in USB-powered instrumentation.
For engineers reviewing the AP7380-44W5-7 datasheet, AP7380-44W5-7 pinout, AP7380-44W5-7 application, or AP7380-44W5-7 equivalent, key selection criteria include dropout performance at 150mA load, thermal shutdown threshold (+160°C), compatibility with low-ESR ceramic capacitors, and SOT25 package footprint constraints for high-density PCB layouts.
Technical Context
The AP7380-44W5-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 4.4V output, current-limit protection (150mA typ), and enable-controlled shutdown with 0.01µA standby current. Its architecture supports stable operation with 1.0µF input/output ceramic capacitors and exhibits ±100ppm/°C output voltage temperature coefficient over –40°C to +125°C.
Line regulation is 0.05%/V and load regulation is 0.5% across 1–150mA, while thermal shutdown activates at +160°C with +20°C hysteresis. The device uses a PMOS pass transistor topology, eliminating external compensation and enabling fast transient response without stability concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.4V ±1% - ensures stable supply for 4.3–4.5V-tolerant logic or analog circuitry without external feedback. |
| Input Voltage Range | 3.5V to 24V - supports direct connection to 12V industrial rails, 9V batteries, or USB PD sources with margin. |
| Dropout Voltage | 500mV @ 50mA - enables >4.9V minimum input for full 4.4V output under mid-load, critical for battery end-of-life operation. |
| Ground Current | 1.8–3.0µA @ IOUT = 0–150mA - minimizes quiescent power loss in always-on sensor nodes or backup power paths. |
| Current Limit | 150mA typical - provides robust short-circuit protection without latch-up, allowing safe recovery after fault removal. |
| Thermal Shutdown | +160°C activation with +20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking in SOT25. |
| ESD Rating | 2500V HBM - ensures handling robustness during assembly and field service in consumer-grade environments. |
Pinout & Package
SOT25 (W5) package: 5-pin surface-mount outline with exposed thermal pad (not electrically connected); footprint compatible with JEDEC TO-236AB; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts 3.5–24V; requires 1.0µF ceramic decoupling close to pin. |
| 2 | GND | Analog/digital ground reference; connects to PCB ground plane for thermal and noise control. |
| 3 | VOUT | Regulated 4.4V output; drives load and requires 1.0µF ceramic capacitor to ensure stability and transient response. |
| 4 | NC | No internal connection; must be left floating or tied to GND per layout best practice - no electrical function. |
| 5 | EN | Active-high enable input; logic-high ≥2.0V enables regulation; ≤0.4V disables output and reduces current to 0.01µA. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3.5–24V) | Eliminates need for pre-regulation stages when powering from variable sources like automotive or industrial 12V rails. |
| Ultra-low quiescent current (1.8–3.0µA) | Extends battery life in always-on IoT sensors by reducing standby power consumption below 15nW per volt. |
| Low-ESR ceramic capacitor support | Enables use of compact, reliable 0603/0805 MLCCs instead of larger, less stable tantalum or aluminum electrolytics. |
| Thermal shutdown with hysteresis | Prevents thermal runaway during overload while avoiding oscillation near trip point due to +20°C recovery margin. |
| ±1% output voltage accuracy | Meets tight tolerance requirements for ADC references, RF biasing, and precision analog subsystems without trimming. |
Applications
| Portable Medical Sensors | USB-Powered Test Instruments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-4402E/MB | 4.4V fixed, 250mA rating, 600mV dropout @ 250mA, 2.5µA IQ, SOT23-5 package | Higher current capability but larger dropout at 150mA; lacks thermal hysteresis | Select when >200mA peak load required and board space permits SOT23-5; verify thermal design at full load. |
| Torex XC6210B442MR-G | 4.4V fixed, 150mA rating, 350mV dropout @ 100mA, 1.0µA IQ, SOT25 package | Lower dropout and IQ, but no enable pin and only 12V max input | Choose for ultra-low-power designs where enable control is unnecessary and input stays ≤12V. |
Compared with MCP1703T-4402E/MB and XC6210B442MR-G, the AP7380-44W5-7 uniquely balances 24V input support, integrated enable, and thermal hysteresis in the same SOT25 footprint - making it optimal for battery-to-12V hybrid systems requiring robust fault management.

FAQ
What is the maximum continuous output current for AP7380-44W5-7?
The AP7380-44W5-7 is rated for 150mA typical continuous output current, with current limiting activating at approximately 150mA under standard test conditions (VIN = VOUT + 2V). Derating is required above +85°C ambient due to thermal resistance of 193°C/W in SOT25; maximum usable current drops to ~90mA at +105°C junction temperature.
Can AP7380-44W5-7 operate with input voltage below 3.5V?
No - the absolute minimum input voltage is 3.5V per the Recommended Operating Conditions table. Operation below this threshold risks improper regulation, increased dropout, or failure to maintain 4.4V output. For sub-3.5V inputs, consider Diodes' AP2204K-44 or similar low-VIN LDOs.
Is the EN pin internally pulled down when not driven?
No - the EN pin has no internal pull-down. It must be actively driven to ≥2.0V for regulation or ≤0.4V for shutdown. Leaving EN floating may result in indeterminate output state due to noise coupling; recommended practice is to tie EN to VIN through a 100kΩ resistor if always-on operation is intended.
Does AP7380-44W5-7 require an external bypass capacitor on the VOUT pin?
Yes - a 1.0µF ceramic capacitor is required on VOUT for stability and transient response, as specified in the Electrical Characteristics table and Typical Applications Circuit. Using lower capacitance or higher-ESR types may cause oscillation or degraded load step recovery, especially under 100mA dynamic loads.
