Product details
Overview
AP7383-50WW-7 from Diodes Incorporated is a fixed-output 5.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 (WW) package. It features 30V max input voltage, 500mV dropout at 50mA, ±1% output accuracy, 1.8µA ground current, and thermal shutdown-designed for USB-powered instrumentation and portable battery systems requiring stable low-noise 5V rail generation.
For engineers reviewing the AP7383-50WW-7 datasheet, AP7383-50WW-7 pinout, AP7383-50WW-7 application, or AP7383-50WW-7 equivalent, key selection criteria include wide-input capability (3.5–30V), ultra-low quiescent current for battery longevity, fixed 5.0V output with tight regulation (±1%), thermal protection, and compatibility with 1µF ceramic capacitors on both input and output.
Technical Context
The AP7383-50WW-7 integrates an error amplifier, precision voltage reference, resistor network for fixed 5.0V output, current-limit circuit (150mA typical), and enable control logic. Its internal architecture supports operation across -40°C to +125°C junction temperature with ±100ppm/°C output voltage drift.
It delivers stable regulation under dynamic load conditions (150mA step) with <200µs transient recovery and maintains line regulation of 0.05%/V and load regulation of 0.5% across full operating range-enabling use in noise-sensitive analog and mixed-signal subsystems without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% - ensures compatibility with 5V logic, USB peripherals, and analog sensors requiring precise biasing. |
| Input Voltage Range | 3.5V to 30V - supports direct connection to unregulated 12V/24V rails, automotive batteries, and multi-cell Li-ion packs. |
| Dropout Voltage | 500mV @ 50mA - enables >4.5V output from 5.0V input, critical for low-headroom battery discharge stages. |
| Ground Current | 1.8µA @ no load - extends shelf life and runtime in always-on IoT nodes and standby circuits. |
| Thermal Shutdown | 160°C activation with 20°C hysteresis - prevents latch-up during sustained overload or poor PCB thermal design. |
| ESD Rating | 2500V HBM - provides robust handling during board assembly and field service without additional protection. |
| Capacitor Compatibility | 1µF ceramic input/output - eliminates need for bulk electrolytics, reducing footprint and improving reliability. |
Pinout & Package
SOT25 (WW) package: 5-pin surface-mount, 2.8mm × 2.9mm × 1.05mm body, matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main power input; accepts up to 30V; requires 1µF ceramic decoupling within 5mm. |
| 2 | GND | Analog/digital ground reference; must connect to low-impedance PCB plane for thermal and noise performance. |
| 3 | VOUT | Regulated 5.0V output; drives loads up to 150mA; requires 1µF ceramic capacitor directly at pin. |
| 4 | NC | No internal connection; recommended to tie to GND for enhanced thermal dissipation via PCB copper. |
| 5 | NC | No internal connection; recommended to tie to GND for enhanced thermal dissipation via PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range | 30V max input enables single-regulator support for 12V/24V industrial buses and automotive cold-crank scenarios. |
| Ultra-Low Quiescent Current | 1.8µA ground current minimizes battery drain in sleep modes-critical for >1-year coin-cell operation. |
| Fixed 5.0V Output Accuracy | ±1% over temperature and load ensures reliable interface with 5V microcontrollers, ADC references, and USB PHYs. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis prevents permanent damage during short-circuit or high-ambient conditions. |
| Low-ESR Ceramic Support | Stable with 1µF X5R/X7R ceramics eliminates electrolytic aging and reduces BOM count and board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5V ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-5002E/MB | 250mV dropout @ 250mA; 2.5µA IQ; 6V max input; SOT23-5 package. | Limited to ≤6V input; unsuitable for 12V/24V industrial or automotive inputs. | Select only if input never exceeds 6V and lower dropout is prioritized over input range. |
| TPS7A2050PDBVR | 175mV dropout @ 300mA; 6.5µA IQ; 6V max input; 1% accuracy; WSON-6 package. | Same 5V output but narrower 1.6–6V input range; higher IQ reduces battery life in always-on designs. | Prefer for ultra-low-dropout needs below 6V; avoid where 12V+ input or µA-level IQ is required. |
Compared with MCP1703T-5002E/MB and TPS7A2050PDBVR, the AP7383-50WW-7 uniquely balances 30V input tolerance, 1.8µA quiescent current, and 500mV dropout-making it the only choice for battery-backed 5V systems operating across automotive, industrial, and USB-C PD voltage domains.

FAQ
What is the maximum continuous output current for AP7383-50WW-7?
The AP7383-50WW-7 delivers 150mA continuous output current under recommended operating conditions (TJ ≤ +125°C, VIN ≤ 30V). Current limit is internally set at 150mA typical, with thermal shutdown activating at 160°C junction temperature to prevent damage during sustained overload or poor heatsinking.
Can AP7383-50WW-7 operate with a 3.7V Li-ion battery input?
No-minimum input voltage is 3.5V, but dropout voltage is 500mV at 50mA. To maintain regulated 5.0V output, VIN must be ≥5.5V at that load. With a 3.7V battery, output collapses below regulation; this device is intended for higher-input systems like 5V USB, 12V industrial rails, or multi-cell battery packs-not single-cell Li-ion.
Is the EN pin functional on AP7383-50WW-7?
No-the AP7383-50WW-7 is the fixed-output, non-enable version in SOT25 (WW) package. Pin 4 and Pin 5 are NC (not connected internally). The enable function is only available in the W5 variant (e.g., AP7383-50W5-7), which uses a different pinout with dedicated EN on Pin 3.
Does AP7383-50WW-7 require external compensation components?
No-AP7383-50WW-7 is internally compensated and stable with 1µF ceramic capacitors on both input and output. No external resistors, capacitors, or feedback networks are needed. This simplifies layout, reduces BOM count, and ensures consistent performance across manufacturing lots without tuning.
