Product details
Overview
AP7383-50W5-7 from Diodes Incorporated is a fixed-output 5.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 package. It operates across 3.5V–30V input range, delivers ±1% output voltage accuracy at 10mA load, maintains 500mV dropout at 50mA, and draws only 1.8µA ground current-enabling long battery life in portable instrumentation and USB-powered devices.
For engineers reviewing the AP7383-50W5-7 datasheet, AP7383-50W5-7 pinout, AP7383-50W5-7 application, or AP7383-50W5-7 equivalent, key selection criteria include wide VIN tolerance, thermal shutdown behavior, EN pin logic thresholds, low-ESR capacitor compatibility, and SOT25 thermal resistance (193°C/W).
Technical Context
The AP7383-50W5-7 integrates an error amplifier, precision voltage reference, resistor network for fixed 5.0V output, current-limit circuit (150mA typ), and enable control with 2.0V high/0.4V low thresholds. Its architecture supports stable regulation under fast load transients while maintaining ultra-low quiescent current across temperature.
Thermal protection activates at +160°C with +20°C hysteresis; line regulation is 0.05%/V and load regulation is 0.5% over 1–150mA. The device requires only 1µF ceramic input/output capacitors and exhibits ±100ppm/°C output voltage drift from –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% at 10mA - ensures stable MCU core or sensor supply without external feedback. |
| Input Voltage Range | 3.5V to 30V - supports direct connection to unregulated 12V/24V rails or multi-cell batteries. |
| Dropout Voltage | 500mV @ 50mA - enables 5.5V input to sustain 5.0V output under full load, minimizing power loss. |
| Ground Current | 1.8µA @ IOUT = 0A - extends battery runtime in always-on monitoring circuits. |
| Current Limit | 150mA typical - provides short-circuit protection without external current-sense components. |
| Thermal Shutdown | Activates at +160°C with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Line Regulation | 0.05%/V - limits output variation to ±0.1V over full 3.5–30V input swing at constant load. |
| Load Regulation | 0.5% from 1mA to 150mA - holds output within ±25mV across full operating current range. |
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 connected to low-impedance PCB plane for thermal and noise performance. |
| 3 | VOUT | Regulated 5.0V output; requires ≥1µF ceramic capacitor placed within 3mm for stability. |
| 4 | EN | Active-high enable input; pulls output to high-impedance state when <0.4V; drives VOUT when >2.0V. |
| 5 | NC | No internal connection; recommended to tie to GND for improved thermal conduction and EMI shielding. |
Key Features
| Feature | Design Value |
|---|---|
| Wide-input operation | 3.5V–30V input range eliminates need for pre-regulation in industrial 12V/24V systems. |
| Ultra-low quiescent current | 1.8µA ground current enables >1-year battery life in 10µA sleep-mode IoT sensors. |
| Low-ESR capacitor compatible | Stable with 1µF ceramic output cap - reduces BOM cost and board area vs. tantalum alternatives. |
| Integrated thermal shutdown | +160°C trip with +20°C hysteresis prevents latch-up and enables safe auto-recovery after fault clearance. |
| High accuracy output | ±1% initial tolerance and ±100ppm/°C drift ensure reliable ADC reference or analog sensor biasing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-5002E/MB | 250mA rated, 600mV dropout @ 250mA, 2.5µA IQ, no EN pin | Lacks enable control; higher dropout limits use below 5.6V input | Select when higher output current is required and enable functionality is unnecessary. |
| TPS7A2050PDBVR | 300mA rated, 170mV dropout @ 300mA, 6.5µA IQ, active-low EN | Lower dropout enables 5.2V input operation; active-low EN requires logic inversion | Choose for tighter dropout margin or higher current, accepting inverted enable polarity and higher quiescent draw. |
Compared with MCP1703T-5002E/MB and TPS7A2050PDBVR, the AP7383-50W5-7 offers superior input voltage range (30V vs. 13.2V/6V), lowest quiescent current (1.8µA), and integrated thermal protection - making it optimal for wide-input, ultra-low-power, and thermally constrained designs.

FAQ
What is the minimum input voltage required for AP7383-50W5-7 to regulate 5.0V output?
The AP7383-50W5-7 requires a minimum input voltage of 3.5V per its Recommended Operating Conditions. However, to maintain regulation at full 150mA load, VIN must exceed VOUT by at least the dropout voltage - which is 1.05V at 150mA (max). Therefore, 6.05V input is needed for guaranteed 5.0V output at maximum current.
Can AP7383-50W5-7 be used with ceramic capacitors smaller than 1µF?
No - the datasheet specifies 1.0µF minimum for both CIN and COUT using X5R/X7R ceramic capacitors. Using smaller values risks instability, overshoot, or oscillation due to insufficient phase margin. The internal compensation is optimized for ≥1µF, and reducing capacitance violates the stability guarantee.
Does AP7383-50W5-7 support reverse-voltage protection?
No - the AP7383-50W5-7 does not include reverse-voltage protection. Applying negative voltage to VIN or VOUT can damage the IC. External protection (e.g., series Schottky diode on VIN or back-to-back MOSFETs) is required if reverse polarity exposure is possible in the target application.
Is the NC pin on AP7383-50W5-7 required to be grounded?
The NC pin (Pin 5) has no internal connection but is recommended to be tied to GND on the PCB. This improves thermal dissipation by increasing copper area under the package and reduces radiated emissions by providing a low-impedance return path for high-frequency noise coupling through the package substrate.
