Product details
Overview
AP7383-30W5-7 from Diodes Incorporated is a fixed-output 3.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 package with 30V max input voltage, 500mV dropout at 50mA, ±1% output accuracy, and 1.8µA quiescent current - designed for USB-powered instrumentation and portable battery systems requiring stable low-noise supply under wide input variation.
For engineers reviewing the AP7383-30W5-7 datasheet, AP7383-30W5-7 pinout, AP7383-30W5-7 application, or AP7383-30W5-7 equivalent, this page delivers verified technical context, validated pin mapping for W5 package, real-world load/line regulation performance, thermal shutdown behavior, and direct alternatives with documented functional trade-offs.
Technical Context
The AP7383-30W5-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.0V output, current-limit circuit (150mA), and enable control - all within a monolithic CMOS process. Its architecture supports operation from 3.5V to 30V input while maintaining regulation down to 3.5V input for 3.0V output.
It features active thermal shutdown at +160°C with +20°C hysteresis, ultra-low ground current (1.8µA at no load), and compatibility with 1µF ceramic input/output capacitors. The EN pin enables logic-level control (2.0V high, 0.4V low), and NC pins are internally unconnected but recommended tied to GND for thermal enhancement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% - ensures stable MCU core or sensor bias without external feedback. |
| Input Voltage Range | 3.5V to 30V - supports direct connection to automotive batteries, industrial rails, or multi-cell Li-ion packs. |
| Dropout Voltage | 360–580mV @ 50mA - enables regulation with only 3.36V input for full 3.0V output under typical load. |
| Quiescent Current | 1.8µA @ IOUT = 0 - extends battery life in always-on monitoring circuits. |
| Line Regulation | 0.05%/V - maintains output stability across wide input swings (e.g., 12V ±20% automotive transients). |
| Load Regulation | 0.5% @ 1–150mA - holds output within ±15mV over full rated current range. |
| Thermal Shutdown | Activates at +160°C with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT25 (W5) package: 5-pin surface-mount, 2.8mm × 2.9mm footprint, 0.95mm height, matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts up to 30V DC with internal overvoltage protection. |
| 2 | GND | Power ground reference; must be low-impedance connection to minimize noise and thermal resistance. |
| 3 | VOUT | Regulated 3.0V output; requires ≥1µF ceramic capacitor placed adjacent to pin for stability. |
| 4 | EN | Active-high enable input; drives device ON when ≥2.0V, OFF when ≤0.4V; draws ≤1µA leakage. |
| 5 | NC | No internal connection; recommended tied to GND to improve thermal dissipation via PCB copper area. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range | Supports 3.5–30V inputs - eliminates need for pre-regulation in 12V/24V industrial or automotive subsystems. |
| Ultra-Low IQ | 1.8µA ground current at zero load - enables >1-year runtime on coin-cell batteries in remote sensors. |
| Ceramic Cap Compatible | Stable with 1µF X5R/X7R MLCCs - reduces BOM cost and board space vs. tantalum or electrolytic solutions. |
| High Accuracy Output | ±1% initial tolerance over temperature - avoids calibration overhead in precision analog front-ends. |
| Thermal Protection | Auto-recovery shutdown at +160°C - sustains reliability during transient overloads without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3002E/MB | 300mA rating, 600mV dropout @ 250mA, 2.5µA IQ, no EN pin | Lacks enable control; higher current capacity unnecessary for 150mA use cases | Select if higher output current headroom is required and EN functionality is not needed. |
| TPS7A2030PDQNR | 200mA rating, 170mV dropout @ 250mA, 6.5µA IQ, EN pin included | Lower dropout enables tighter input margins but higher IQ reduces battery life in always-on designs | Select for ultra-low-dropout priority in space-constrained designs where 6.5µA IQ is acceptable. |
Compared with MCP1703T-3002E/MB and TPS7A2030PDQNR, the AP7383-30W5-7 uniquely balances ultra-low IQ (1.8µA), integrated EN control, and 30V input capability - making it optimal for battery-backed instrumentation where standby efficiency and input ruggedness are co-critical.

FAQ
What is the minimum input voltage required for regulation at 3.0V output?
The AP7383-30W5-7 requires VIN ≥ 3.5V to maintain regulation at 3.0V output across temperature and load. At 50mA load, dropout is 360–580mV, so 3.36V input suffices for full specification compliance. Below 3.5V, output drops linearly with input.
Can the NC pin be left floating on the SOT25 (W5) package?
No - Pin 5 (NC) is not internally connected but must be tied to GND on the PCB. This maximizes copper area for heat conduction from the die paddle, improving thermal resistance by ~15% and enabling higher continuous current in compact layouts.
Does the AP7383-30W5-7 require an input capacitor?
Yes - a minimum 1.0µF ceramic capacitor (X5R/X7R) is required between VIN and GND, placed within 3mm of the device. This stabilizes the input rail against source impedance and suppresses high-frequency noise that could affect regulation or cause oscillation.
Is the AP7383-30W5-7 qualified for automotive applications?
No - the AP7383-30W5-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7383-30W5Q-7) with PPAP documentation, extended temperature testing (-40°C to +125°C), and IATF 16949 manufacturing - contact Diodes directly for those versions.
