Product details
Overview
AP7383-36Y-13 from Diodes Incorporated is a fixed-output 3.6V, 150mA ultra-low dropout (ULDO) linear regulator in SOT89 package, featuring 30V max input voltage, 500mV dropout at 50mA, ±1% output accuracy, and 1.8µA quiescent current - designed for stable power delivery in battery-powered instrumentation and portable USB devices.
For engineers reviewing the AP7383-36Y-13 datasheet, AP7383-36Y-13 pinout, AP7383-36Y-13 application, or AP7383-36Y-13 equivalent, key selection criteria include wide-input capability (3.5–30V), thermal shutdown at +160°C, EN control support in W5 variant, low-ESR ceramic capacitor compatibility, and junction temperature range of –40°C to +125°C.
Technical Context
The AP7383-36Y-13 implements a precision bandgap reference with error amplifier feedback to maintain 3.6V output within ±1% over line, load, and temperature. Its internal current-limit circuit protects against overload up to 150mA, and thermal shutdown activates at +160°C with +20°C hysteresis.
No enable (EN) function is implemented in the SOT89 (Y) package variant - pins are VIN (1), GND (2), VOUT (3); the EN terminal exists only in SOT25 W5/WR/WW packages. Dropout behavior is characterized across 50–150mA loads and –40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6V ±1% - ensures stable rail for 3.3V–3.6V logic and analog subsystems without external resistors. |
| Input Voltage Range | 3.5V to 30V - supports direct connection to unregulated 12V/24V rails or multi-cell Li-ion batteries. |
| Max Output Current | 150mA - sufficient for microcontrollers, sensors, and low-power RF modules in portable designs. |
| Dropout Voltage | 500mV @ 50mA - enables regulation down to VIN = 4.1V, critical for end-of-battery-life operation. |
| Quiescent Current | 1.8µA - minimizes standby power loss in always-on monitoring circuits. |
| Thermal Shutdown | +160°C activation with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
| Line Regulation | 0.05%/V - maintains tight output stability despite input ripple or supply sag in automotive or industrial environments. |
Pinout & Package
SOT89 package (3-pin, single-row, gull-wing leads) with exposed thermal pad on underside; footprint dimensions: D = 4.50mm, E = 2.50mm, H = 4.10mm; moisture sensitivity level 3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts 3.5–30V; requires 1µF input capacitor for stability. |
| 2 | GND | Analog/digital ground reference; must be connected to low-impedance PCB ground plane for thermal and noise performance. |
| 3 | VOUT | Regulated 3.6V output; requires 1µF low-ESR ceramic capacitor at device pin for transient response and loop stability. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range Support | 30V absolute max rating enables use with 24V industrial buses or 9–12V wall adapters without pre-regulation. |
| Low Ground Current | 1.8µA at zero load reduces system-level standby consumption - critical for battery life in IoT edge nodes. |
| Ceramic Capacitor Compatibility | Stable with ≥1µF X5R/X7R ceramics - eliminates need for costly tantalum or aluminum electrolytics. |
| High Accuracy Output | ±1% initial tolerance over temperature ensures reliable ADC reference, sensor biasing, and MCU core voltage compliance. |
| Thermal Protection | Auto-recovery shutdown prevents latch-up during short-circuit events or inadequate heatsinking on SOT89 PCB land pattern. |
Applications
| Portable Medical Sensors | Industrial Data Loggers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3602E/MB | 250mA rated, 600mV dropout @ 250mA, 2.5µA IQ, no thermal shutdown | Lacks thermal protection; higher dropout limits usable input range in low-VIN scenarios | Select when higher current headroom is needed and thermal margin is guaranteed by PCB layout |
| TPS7A2036PDQNR | 300mA rated, 170mV dropout @ 300mA, 6.5µA IQ, integrated EN, smaller X2SON-4 package | Lower dropout improves efficiency but requires enable control and tighter layout for thermal management | Prefer for space-constrained designs where 170mV dropout enables longer battery runtime at light loads |
Compared with MCP1703T-3602E/MB and TPS7A2036PDQNR, the AP7383-36Y-13 offers superior thermal safety and lower quiescent current, making it optimal for thermally unmanaged, battery-sensitive applications - though its 150mA limit and SOT89 size constrain high-current or ultra-compact use cases.

FAQ
What is the minimum input voltage required for regulation at 3.6V output?
The AP7383-36Y-13 requires a minimum input voltage of 3.5V to maintain regulation, as specified in Recommended Operating Conditions. At 50mA load, dropout is 500mV - meaning VIN must be ≥4.1V for full-load stability. Below 3.5V, the device enters dropout and output voltage declines linearly with input.
Does AP7383-36Y-13 support enable/disable functionality?
No - the SOT89 (Y) package variant has only three pins (VIN, GND, VOUT) and does not implement an enable input. Enable functionality is available only in SOT25 packages (W5/WR/WW), where Pin 4 is designated EN. For on/off control in SOT89 designs, external MOSFET switching on the input rail is required.
Can AP7383-36Y-13 be used with aluminum electrolytic capacitors?
While functional, aluminum electrolytics are not recommended. The AP7383 is optimized for low-ESR ceramic capacitors (≥1µF X5R/X7R). Aluminum types exhibit higher ESR and aging effects, which may degrade transient response and cause instability or overshoot during load steps - confirmed in Typical Performance Characteristics plots showing optimal behavior with 1µF ceramics.
What is the thermal resistance (θJA) of the SOT89 package under standard JEDEC conditions?
The SOT89 package has θJA = 118°C/W when mounted on a 2-inch × 2-inch JEDEC High-K test board with 1oz internal planes and 2oz top/bottom copper. This value assumes full thermal pad soldering to a dedicated ground plane; actual PCB layout will significantly affect real-world thermal performance.
