Product details
Overview
AP7380-50WR-7 from Diodes Incorporated is a fixed 5.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 (WR) package. It operates across 3.5V–24V input range, delivers ±1% output voltage accuracy at 10mA load, features 500mV dropout at 50mA, and draws only 1.8µA ground current at full load - enabling long battery life in portable instrumentation and USB-powered devices.
For engineers reviewing the AP7380-50WR-7 datasheet, AP7380-50WR-7 pinout, AP7380-50WR-7 application, or AP7380-50WR-7 equivalent, key selection criteria include wide VIN tolerance, thermal shutdown at +160°C, compatibility with low-ESR ceramic capacitors, and EN-controlled standby mode drawing just 0.01µA.
Technical Context
The AP7380-50WR-7 integrates an error amplifier, precision voltage reference, resistor network for fixed 5.0V output, current-limit protection (150mA), and enable-controlled shutdown. Its architecture supports stable regulation under fast load transients while maintaining ultra-low quiescent current across -40°C to +125°C junction temperature.
It employs internal thermal shutdown with +20°C hysteresis and achieves ±100ppm/°C output voltage drift over temperature. Line regulation is 0.05%/V and load regulation is 0.5% across 1–150mA, confirming high stability in variable-input, low-power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% at 10mA - ensures precise logic-level supply for microcontrollers and sensors. |
| Input Voltage Range | 3.5V to 24V - supports direct connection to 12V rails, automotive batteries, and multi-cell Li-ion packs. |
| Dropout Voltage | 250mV (typ) @ 50mA - enables regulation down to VIN = 5.25V, critical for energy harvesting and low-VIN backup supplies. |
| Ground Current | 1.8µA (typ) @ IOUT = 150mA - minimizes parasitic drain in always-on battery systems. |
| Thermal Shutdown | +160°C with +20°C hysteresis - provides robust self-protection during sustained overload or poor heatsinking. |
| Enable Input Threshold | VIH = 2.0V, VIL = 0.4V - compatible with 3.3V and 5V GPIOs without level-shifting. |
| Output Accuracy vs Temp | ±100ppm/°C - maintains tight regulation across industrial temperature range (-40°C to +125°C). |
Pinout & Package
SOT25 (WR) package: 5-pin, surface-mount, moisture-sensitivity Level 1, matte tin-plated leads, 0.016g mass, footprint per JEDEC MO-178AB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be low-impedance connection to minimize noise and dropout variation. |
| 2 | VIN | Main input supply pin; accepts up to 24V DC with transient tolerance to 30V absolute max. |
| 3 | VOUT | Regulated 5.0V output; requires ≥1.0µF low-ESR ceramic capacitor for stability. |
| 4 | NC | No-connect terminal; electrically isolated and not bonded - must remain unconnected on PCB. |
| 5 | EN | Active-high enable; pulls device into 0.01µA standby when driven ≤0.4V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3.5V–24V) | Eliminates need for pre-regulation stages in mixed-voltage systems like USB-C PD adapters and industrial sensors. |
| Ultra-low quiescent current (1.8µA) | Extends shelf life and runtime in battery-backed real-time clocks, IoT edge nodes, and wearables. |
| Ceramic capacitor compatibility | Reduces BOM count and board area by removing ESR requirements - supports 1µF input/output ceramics. |
| Thermal shutdown with hysteresis | Prevents thermal runaway during short-circuit events while avoiding oscillation near trip point. |
| High accuracy (±1%) and low drift (±100ppm/°C) | Meets precision analog supply needs for ADC references, op-amp biasing, and sensor signal chains. |
Applications
| Portable Medical Sensors | USB-Powered Test Equipment |
|---|---|
|
Use Scenario: Continuous glucose monitor with BLE radio and low-power MCU operating from single Li-ion cell (3.0–4.2V) plus 12V external charger path. IC Role / Device Role / Timing Role: Primary 5.0V LDO supplying MCU, sensor interface, and RF transceiver; enabled only during active measurement cycles. Use Value: 1.8µA ground current extends battery life beyond 7 days; 500mV dropout allows operation down to 4.5V input during discharge. |
Use Scenario: Handheld oscilloscope module powered via USB 2.0 (5V) or external 12V adapter, requiring clean 5.0V rail for analog front-end and FPGA core. IC Role / Device Role / Timing Role: Post-regulator isolating noisy USB bus from sensitive analog circuitry; bypassed during high-current FPGA configuration. Use Value: 0.05%/V line regulation rejects USB port voltage sag; thermal shutdown protects against enclosure overheating during extended use. |
| Industrial Data Loggers | Automotive Body Control Modules |
|
Use Scenario: Remote environmental logger using 4xAA alkaline pack (4.0–6.8V) and solar trickle charge, logging data every 15 minutes. IC Role / Device Role / Timing Role: Always-on 5.0V supply for RTC, flash memory, and wake-up controller; EN toggled by microcontroller before each read cycle. Use Value: 0.01µA standby current reduces annual self-discharge to <1% of battery capacity; ±1% accuracy ensures reliable EEPROM write margins. |
Use Scenario: Door module with LIN transceiver, LED drivers, and position sensors, powered from vehicle battery (9–16V) with cold-crank dips to 6V. IC Role / Device Role / Timing Role: Secondary 5.0V regulator for microcontroller and CAN/LIN PHYs; withstands 24V load-dump transients via upstream TVS. Use Value: 24V max input rating avoids need for additional clamping; ±100ppm/°C drift maintains timing integrity across -40°C to +105°C ambient. |
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 |
|---|---|---|---|
| MCP1700-5002E/TO | Lower max input (6V), higher dropout (600mV @ 250mA), no EN pin, TO-92 package. | Limited to single-cell battery systems; lacks enable control and thermal shutdown. | Choose only for cost-sensitive, low-input, non-automotive designs where enable and thermal protection are unnecessary. |
| TNIV50050X | Same 24V max input, but 200mA rating, 300mV dropout @ 100mA, SOT23-5 package, no thermal shutdown. | Higher current capability but reduced safety margin; smaller footprint limits thermal dissipation. | Select when >150mA load is required and thermal derating can be managed externally via layout or airflow. |
Compared with MCP1700-5002E/TO and TNIV50050X, the AP7380-50WR-7 uniquely combines 24V input tolerance, EN control, thermal shutdown, and sub-µA standby - making it optimal for USB, portable instrumentation, and automotive body electronics where reliability and wide VIN are mandatory.

FAQ
What is the minimum input voltage required for regulation at 5.0V output?
The AP7380-50WR-7 requires VIN ≥ VOUT + VDROP. At 50mA load, typical dropout is 250mV, so minimum VIN is 5.25V. At 150mA, worst-case dropout is 1100mV, raising minimum VIN to 6.1V. The datasheet specifies 3.5V as absolute minimum, but regulation is only guaranteed above VOUT + VDROP across load and temperature.
Can the AP7380-50WR-7 be used without the EN pin connected?
Yes - the EN pin is internally pulled high, so the device powers up enabled by default when VIN is applied. Leaving EN unconnected is acceptable for always-on applications. However, tying EN to GND disables the output and reduces current draw to 0.01µA, which is recommended for battery conservation in sleep modes.
Is a minimum output capacitor required, and what type is recommended?
Yes - a minimum 1.0µF ceramic capacitor with X5R or X7R dielectric is required at VOUT for stability. The datasheet confirms compatibility with low-ESR ceramics and specifies no ESR minimum, eliminating need for tantalum or aluminum electrolytics. Larger values (e.g., 10µF) improve transient response but are not mandatory.
Does the AP7380-50WR-7 support automotive qualification?
No - the AP7380-50WR-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7380Q series) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. This WR-packaged part is intended for commercial/industrial use; automotive designs require explicit Q-part numbers and qualification evidence.
