Product details
Overview
AP7387Q-30Y-13 from Diodes Incorporated is an automotive-grade 3.0V fixed-output ultra-low-dropout linear regulator with 60V max input voltage, 150mA output current capability, 700mV dropout at 100mA, ±2% output accuracy, and 2μA quiescent current - designed for power supply in harsh-automotive environments such as body control modules and battery management systems.
For engineers reviewing the AP7387Q-30Y-13 datasheet, AP7387Q-30Y-13 pinout, AP7387Q-30Y-13 application, or AP7387Q-30Y-13 equivalent, key selection criteria include wide-input-voltage operation (5–60V), AEC-Q100 qualification, thermal shutdown behavior, PSRR performance at 1kHz, and SOT89 package thermal resistance (78.6°C/W).
Technical Context
The AP7387Q-30Y-13 integrates a precision voltage reference, error amplifier, and internal resistor network to deliver stable 3.0V output across -40°C to +125°C ambient. Its architecture includes current-limit protection (250mA typ.), short-circuit detection, and thermal shutdown triggered at +150°C with +30°C hysteresis.
It achieves high PSRR (70dB @1kHz) and fast transient response via optimized internal compensation and low-impedance pass element design. Input stability requires ≥1µF ceramic capacitor; output stability requires ≥10µF X7R/X5R ceramic capacitor placed adjacent to VOUT/GND pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 5V to 60V - supports direct connection to automotive battery rails including load-dump transients up to 60V. |
| Output Voltage | 3.0V ±2% - tight regulation enables reliable powering of 3.3V-tolerant MCUs and CAN/LIN transceivers with margin. |
| Max Output Current | 150mA - sufficient for low-power microcontrollers, sensor interfaces, and communication ICs in body electronics. |
| Dropout Voltage | 700mV @100mA - allows operation down to VIN = 3.7V while maintaining regulated 3.0V output in cold-crank conditions. |
| Quiescent Current | 2μA (typ.) - enables always-on functionality in vehicle sleep modes without excessive battery drain. |
| PSRR | 70dB @1kHz - suppresses ripple from noisy 12V/48V bus, critical for analog-sensing and RF subsystems. |
| Thermal Shutdown | +150°C with +30°C hysteresis - protects against sustained overload or poor PCB thermal design in confined enclosures. |
Pinout & Package
SOT89 package (3-pin, exposed tab) with standard pinout: Pin 1 = VIN, Pin 2 = GND, Pin 3 = VOUT; exposed tab electrically connected to GND and used for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input supply connection | Accepts 5–60V DC; requires ≥1µF ceramic decoupling capacitor placed adjacent to minimize noise coupling. |
| GND (Pin 2 & Tab) | Power ground reference | Primary return path for input/output current; exposed tab must be soldered to large copper area for thermal relief (θJA = 78.6°C/W). |
| VOUT (Pin 3) | Regulated output node | Delivers stable 3.0V ±2%; requires ≥10µF ceramic output capacitor placed within 2mm of pin for transient stability. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (5–60V) | Enables single-regulator solution across 12V, 24V, and 48V automotive architectures without external pre-regulation. |
| AEC-Q100 qualified | Qualified to Grade 1 (-40°C to +125°C), PPAP-capable, and manufactured in IATF 16949 certified facilities for production automotive use. |
| Ultra-low IQ (2μA) | Reduces standby current in always-on domains - e.g., door module wake-up circuits - extending battery life during vehicle sleep. |
| Fast transient response | Stabilizes within <2ms after 10–150mA load step, minimizing voltage droop on MCU core supplies during burst-mode operation. |
| Integrated protections | Combines current limit (250mA), short-circuit shutdown, and thermal foldback - eliminates need for external fault-handling circuitry. |
Applications
| Automotive Body Control Module (BCM) | EV Battery Management System (BMS) Sensor Interface |
|---|---|
|
Use Scenario: Powering 3.3V-tolerant microcontrollers and LIN transceivers in door modules, seat controllers, and lighting nodes. IC Role / Device Role / Timing Role: Primary 3.0V LDO supplying MCU core logic and communication peripherals under varying battery conditions (cold crank, load dump). Use Value: Maintains regulation down to VIN = 3.7V and withstands 60V transients - eliminating need for external TVS or pre-regulator stages. |

Use Scenario: Powering audio DSP cores, display controllers, and USB interface ICs in infotainment head units. IC Role / Device Role / Timing Role: Low-noise 3.0V source for mixed-signal subsystems sensitive to supply ripple and EMI. Use Value: 2μA quiescent current supports low-power audio standby mode; fast line transient response prevents audible pop/click during ignition cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-dropout automotive regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73330PQDBVRQ1 | 300mA output, 220mV dropout @150mA, 25μA IQ, SOT-23-5 package | Higher current, lower dropout, but higher IQ and smaller thermal mass - less suitable for high-temp, low-IQ BCM nodes | Prefer when >150mA load or <220mV dropout is required; verify thermal derating in SOT-23 layout. |
| MAX6675AATC+T | 3.3V output only, 200mA, 350mV dropout @100mA, 3.5μA IQ, TDFN-6 package | Fixed 3.3V output, no 3.0V option; lacks AEC-Q100 qualification and automotive change control | Only for non-automotive industrial designs requiring similar specs but no automotive compliance. |
Compared with TLV73330PQDBVRQ1 and MAX6675AATC+T, the AP7387Q-30Y-13 uniquely balances ultra-low IQ (2μA), 60V input tolerance, AEC-Q100 qualification, and SOT89 thermal performance - making it optimal for cost-sensitive, thermally constrained automotive body electronics.

FAQ
What is the maximum allowable input voltage for AP7387Q-30Y-13?
The absolute maximum input voltage is 80V, but the recommended operating range is 5V to 60V per datasheet Section 5. This 60V upper limit ensures safe operation during automotive load-dump events defined by ISO 7637-2 Pulse 5a, and aligns with the device's internal protection design and thermal limits in SOT89 packaging.
Does AP7387Q-30Y-13 require an external output capacitor, and what type is recommended?
Yes - a minimum 10µF X7R or X5R ceramic capacitor is required at the VOUT pin for stability and transient response, as specified in Section 9.1 of the datasheet. The capacitor must be placed within 2mm of VOUT and GND pins; larger values improve load-step immunity but do not compromise stability due to the internally compensated design.
How does the thermal shutdown function behave during sustained overload?
When junction temperature reaches +150°C, the device shuts down the pass transistor and holds VOUT at zero until temperature drops by ≥30°C (hysteresis), then automatically resumes regulation. This cycle prevents permanent damage during continuous overcurrent or poor heatsinking, and is verified across -40°C to +125°C ambient per Section 6.2 of the datasheet.
Is AP7387Q-30Y-13 pin-compatible with other members of the AP7387Q family?
No - all AP7387Q variants share identical SOT89 pinout (VIN-GND-VOUT), but output voltage is fixed per part number (e.g., -30Y = 3.0V, -33Y = 3.3V). Swapping part numbers changes only the internal feedback divider; no external resistor network is needed, and pin functions remain fully consistent across voltage options.
