Product details
Overview
AP7380-44Y-13 from Diodes Incorporated is a fixed-output 4.4V ultra-low dropout (ULDO) linear regulator IC designed for space-constrained, battery-powered systems. It delivers up to 150mA output current with 500mV dropout at 50mA, ±1% output voltage accuracy, and 1.8µA ground current at zero load - enabling long runtime in portable instrumentation and USB-powered devices.
For engineers reviewing the AP7380-44Y-13 datasheet, AP7380-44Y-13 pinout, AP7380-44Y-13 application, or AP7380-44Y-13 equivalent, key selection criteria include wide 3.5–24V input range, thermal shutdown protection, compatibility with low-ESR ceramic capacitors, and SOT89 (Option 2) package suitability for moderate-power thermal management.
Technical Context
The AP7380-44Y-13 integrates an error amplifier, precision voltage reference, resistor network for fixed 4.4V output, current-limit circuitry (150mA typical), and enable control logic. Its architecture supports stable regulation under fast load transients and wide input variation without external compensation.
It features thermal shutdown at +160°C with +20°C hysteresis, ±100ppm/°C output voltage temperature coefficient, and EN pin logic thresholds of 2.0V (high) and 0.4V (low), enabling direct interfacing with 3.3V/5V microcontroller GPIOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.4V ±1% - ensures stable supply for 4.3–4.5V tolerant logic or analog circuitry. |
| Input Voltage Range | 3.5V to 24V - supports direct connection to 5V, 9V, 12V, or 24V rails including automotive battery inputs. |
| Dropout Voltage | 500mV @ 50mA - enables regulation down to VIN = 4.9V, critical for extending battery life in single-cell Li-ion or multi-cell alkaline systems. |
| Ground Current | 1.8µA @ IOUT = 0mA - minimizes standby power loss in always-on sensor nodes or sleep-mode peripherals. |
| Current Limit | 150mA typical - provides robust short-circuit protection without requiring external current-sense components. |
| Thermal Shutdown | +160°C with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Line Regulation | 0.05%/V - maintains tight output stability across full input range, reducing need for post-regulation filtering. |
| Load Regulation | 0.5% @ 1–150mA - ensures consistent voltage delivery from idle to full-load conditions in portable equipment. |
Pinout & Package
SOT89 (Option 2) package: 3-pin, surface-mount, thermally enhanced plastic outline with exposed tab (pin 2) connected to GND for improved heat dissipation. Dimensions: 4.60 × 2.60 × 1.50 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts 3.5–24V; requires 1µF ceramic input capacitor for stability. |
| 2 | GND | Power ground and thermal pad; must be soldered to large copper area for θJA = 118°C/W performance. |
| 3 | VOUT | Regulated 4.4V output; requires 1µF ceramic output capacitor; low ESR tolerance simplifies layout. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range Support | Operates from 3.5V to 24V - eliminates need for pre-regulation stages in mixed-voltage industrial or automotive subsystems. |
| Ultra-Low Quiescent Current | 1.8µA ground current at no load - extends shelf life and operational time in battery-backed real-time clocks or IoT edge sensors. |
| Ceramic Capacitor Compatibility | Stable with ≥1µF X5R/X7R ceramics - avoids costly tantalum or electrolytic capacitors and reduces board area. |
| Integrated Enable Control | EN pin with 0.4V/2.0V logic thresholds - allows precise power sequencing and firmware-controlled rail activation. |
| Thermal Protection | Auto-recovery shutdown at +160°C - sustains reliability in enclosed enclosures or high-ambient environments without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-4402E/TO | 300mA rating, 175mV dropout @ 250mA, SOT23-5 package, no EN pin | Lacks enable control; higher dropout unsuitable for sub-5V battery cutoff; smaller package limits thermal headroom | Prefer when higher current and simpler enable-free design suffice, and thermal budget permits SOT23-5 |
| TPS7A2044PDBVR | 300mA, 130mV dropout @ 300mA, 25µA IQ, SOT23-5, integrated EN with 0.4V threshold | Lower dropout improves efficiency but higher IQ reduces battery life; smaller package increases thermal resistance | Choose when input voltage stays >4.53V and thermal margin is available; avoid in extended-temp or high-ambient designs |
Compared with MCP1700-4402E/TO and TPS7A2044PDBVR, the AP7380-44Y-13 offers superior thermal performance in SOT89, lower IQ for ultra-low-power sleep modes, and guaranteed 150mA delivery with built-in thermal shutdown - making it optimal for ruggedized portable instrumentation where reliability trumps minimal footprint.

FAQ
What is the maximum input voltage the AP7380-44Y-13 can withstand?
The AP7380-44Y-13 has an absolute maximum input voltage rating of 30V, but its recommended operating range is 3.5V to 24V. Operation above 24V risks exceeding thermal limits or degrading long-term reliability, even if within absolute max ratings. For 24V nominal systems, ensure transient suppression is implemented on the VIN line.
Does the AP7380-44Y-13 require external capacitors, and what values are recommended?
Yes - the AP7380-44Y-13 requires a minimum 1.0µF ceramic capacitor on both input (CIN) and output (COUT) pins. Diodes specifies X5R or X7R dielectrics with ≤100mΩ ESR. Larger values (e.g., 2.2µF) improve transient response but are not required for stability. No series resistor or feedforward capacitor is needed.
How does the EN pin function, and what logic levels activate the regulator?
The EN pin is active-high with VIH = 2.0V (min) and VIL = 0.4V (max). Pulling EN ≥2.0V enables regulation; pulling EN ≤0.4V disables output and reduces ground current to 0.01µA (standby mode). The pin has 1µA leakage and no internal pull-up/down, so external biasing is required for defined startup behavior.
Is the AP7380-44Y-13 qualified for automotive applications?
No - the AP7380-44Y-13 is not AEC-Q100 qualified. Diodes explicitly states that automotive-grade versions require separate qualification, PPAP capability, and IATF 16949 manufacturing. This part is intended for commercial/industrial use only; for automotive designs, contact Diodes directly for qualified alternatives like the AP7361 series.
