Product details
Overview
AP7380-50W5-7 from Diodes Incorporated is a fixed 5.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 package, featuring 24V max input voltage, 500mV dropout at 50mA, ±1% output accuracy, and 1.8µA ground current at zero load - designed for USB-powered instrumentation and portable computing power rails.
For engineers reviewing the AP7380-50W5-7 datasheet, AP7380-50W5-7 pinout, AP7380-50W5-7 application, or AP7380-50W5-7 equivalent, key selection criteria include wide VIN range (3.5–24V), thermal shutdown at +160°C, compatibility with low-ESR ceramic capacitors, and AEC-Q200 readiness for industrial-grade reliability.
Technical Context
The AP7380-50W5-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 5.0V output, current-limit protection (150mA typ), and enable-controlled chip shutdown. Its architecture supports stable regulation across -40°C to +125°C junction temperature with <±100ppm/°C output drift.
It operates without external compensation, uses only 1.0µF input/output ceramic capacitors, and delivers 0.05%/V line regulation and 0.5% load regulation over full output current range - enabling compact, low-noise power delivery in space-constrained battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% - ensures stable logic supply for microcontrollers and USB peripherals without external feedback. |
| Input Voltage Range | 3.5V to 24V - supports direct connection to unregulated 12V/24V rails or multi-cell battery stacks. |
| Dropout Voltage | 250mV (typ) @ 50mA - enables regulation down to VIN = 5.25V, critical for battery end-of-life operation. |
| Ground Current | 1.8µA @ IOUT = 0mA - minimizes standby power loss in always-on sensor nodes and sleep-mode devices. |
| Thermal Shutdown | +160°C with +20°C hysteresis - provides robust overtemperature protection without latch-up or manual reset. |
| Line Regulation | 0.05%/V - maintains output stability despite input ripple or adapter variation in wall-powered applications. |
| Load Regulation | 0.5% (1mA–150mA) - ensures consistent voltage under dynamic load changes in portable computing subsystems. |
Pinout & Package
SOT25 (W5) 5-pin surface-mount package with exposed thermal pad (pin 4); footprint optimized for thermal dissipation in high-ambient environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference and thermal conduction path to PCB copper pour. |
| 2 | VIN | Main input supply connection; accepts up to 24V with internal overvoltage protection. |
| 3 | VOUT | Regulated 5.0V output; requires ≥1.0µF low-ESR ceramic capacitor for stability. |
| 4 | NC | No-connect terminal; internally unused in fixed-output version - must be left floating or grounded per layout guidelines. |
| 5 | EN | Active-high enable input; pulls device into ultra-low standby mode (<0.01µA) when driven low. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range Support | Operates from 3.5V to 24V - eliminates need for pre-regulation stages in mixed-voltage systems. |
| Ultra-Low Quiescent Current | 1.8µA ground current at no load - extends battery life in always-on IoT endpoints by >3× vs. standard LDOs. |
| Ceramic Capacitor Compatibility | Stable with 1.0µF input/output ceramics - reduces BOM count and board area vs. tantalum-based solutions. |
| Thermal Protection with Hysteresis | +160°C trip with +20°C recovery margin - prevents thermal cycling damage during sustained overload. |
| High Output Accuracy | ±1% over temperature and line/load - meets tight tolerance requirements for ADC references and analog sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-5002E/TT (Microchip) | 250mA rating, 1.6µA IQ, but limited to 6V max VIN. | Suitable only for low-input systems (e.g., single Li-ion); cannot replace AP7380 in 12V/24V industrial use. | Select when input never exceeds 6V and higher current headroom is needed. |
| Torex XC6206P502MR-G | 150mA, 1.0µA IQ, 6V max VIN, no EN pin. | Lacks enable control and wide-VIN capability; requires external switch for power gating. | Choose only for cost-sensitive, low-VIN consumer designs where EN functionality is unnecessary. |
Compared with MCP1700T-5002E/TT and XC6206P502MR-G, the AP7380-50W5-7 uniquely combines 24V input tolerance, integrated enable, and ±1% accuracy in a thermally enhanced SOT25 - making it the only drop-in solution for industrial USB-C PD adapters and battery-backed instrumentation.

FAQ
What is the maximum allowable input voltage for AP7380-50W5-7?
The absolute maximum input voltage is 30V, but the recommended operating range is 3.5V to 24V per datasheet DS39196 Rev. 4-2. Operation above 24V risks exceeding thermal limits under load and violates specified safe operating area conditions.
Does AP7380-50W5-7 require an external capacitor on the EN pin?
No external capacitor is required on the EN pin. The enable circuit is CMOS-compatible with TTL logic levels (VIH ≥ 2.0V, VIL ≤ 0.4V) and draws only 1µA typical input current - allowing direct connection to microcontroller GPIO without filtering or pull-up components.
Can AP7380-50W5-7 drive a 150mA load continuously at +85°C ambient?
Yes, provided the PCB layout includes ≥2cm² of 2-oz copper connected to pin 1 (GND) and pin 4 (thermal pad). Thermal resistance θJA is 193°C/W in SOT25; at 150mA and 500mV dropout, power dissipation is 75mW, resulting in ~14.5°C junction rise above ambient - well within the +125°C max TJ rating.
Is AP7380-50W5-7 compliant with AEC-Q200 for automotive use?
The AP7380 series is not AEC-Q200 qualified in standard form, but Diodes offers automotive-grade variants (e.g., AP7380-50W5Q-7) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. Standard AP7380-50W5-7 is rated for industrial (-40°C to +125°C) operation only.
