Product details
Overview
AP7380-36Y-13 from Diodes Incorporated is a fixed 3.6V, 150mA ultra-low dropout (ULDO) linear regulator in SOT89 (Option 2) package, featuring 24V max input voltage, 360mV typical dropout at 50mA, ±1% output voltage accuracy, 1.8µA ground current at zero load, and thermal shutdown protection. It powers USB peripherals, portable instrumentation, and battery-backed subsystems where wide VIN range and low quiescent current are critical.
For engineers reviewing the AP7380-36Y-13 datasheet, AP7380-36Y-13 pinout, AP7380-36Y-13 application, or AP7380-36Y-13 equivalent, key selection criteria include dropout performance under 150mA load, thermal resistance (118°C/W for SOT89), EN pin logic thresholds (2.0V high / 0.4V low), and compatibility with 1µF ceramic output capacitors.
Technical Context
The AP7380-36Y-13 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.6V output, current-limit circuit (150mA typ), and enable-controlled biasing. Its architecture supports stable regulation across -40°C to +125°C junction temperature with ±100ppm/°C output voltage drift.
It operates with input voltages from 3.5V to 24V and maintains line regulation of 0.05%/V and load regulation of 0.5% over 1–150mA output current. Thermal shutdown activates at +160°C with +20°C hysteresis, ensuring safe operation during overload or ambient rise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6V ±1% - ensures stable MCU core or sensor supply without external feedback components. |
| Max Input Voltage | 24V - supports direct connection to 12V/24V industrial rails or automotive battery inputs with transient margin. |
| Dropout Voltage | 360mV @ 50mA - enables regulation down to VIN = 4.0V, critical for single-cell Li-ion (3.0–4.2V) backup operation. |
| Ground Current | 1.8µA @ IOUT = 0mA - minimizes standby power loss in always-on battery-powered systems. |
| Thermal Resistance θJA | 118°C/W (SOT89) - defines junction-to-ambient temperature rise per watt; enables ~1.2W continuous dissipation at TA = 85°C. |
| Enable Threshold | VEN_H = 2.0V, VEN_L = 0.4V - compatible with 3.3V GPIO control without level-shifting; supports deep-sleep wake-up sequencing. |
| ESD Rating | HBM 2500V, MM 250V - provides robust handling during PCB assembly and field operation 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 3.6V output; stable with 1µF ceramic capacitor; no ESR requirement simplifies layout. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3.5–24V) | Eliminates need for pre-regulation stages when interfacing with unregulated 12V/24V sources or multi-cell batteries. |
| Ultra-low IQ (1.8µA) | Extends battery life in always-on IoT sensors and real-time clock backup circuits by minimizing quiescent drain. |
| Low dropout (360mV @ 50mA) | Enables efficient 3.6V rail generation from partially discharged Li-ion cells (≥4.0V), preserving usable capacity. |
| Thermal shutdown with hysteresis | +160°C trip with +20°C hysteresis prevents cycling during sustained overload; protects PCB and adjacent components. |
| Fixed-output accuracy (±1%) | Meets tight tolerance requirements for ADC references, RF front-end biasing, and low-voltage microcontroller cores. |

FAQ
What is the minimum input voltage required for regulation at 3.6V output?
The AP7380-36Y-13 requires a minimum input voltage of 3.5V to maintain regulation. At 50mA load, its typical dropout is 360mV, so stable 3.6V output is guaranteed for VIN ≥ 4.0V. Below 3.5V, the device enters dropout and VOUT tracks VIN minus dropout voltage.
Can the AP7380-36Y-13 be used without an enable signal?
Yes - the EN pin is internally pulled up; leaving it unconnected defaults the device to enabled state. For guaranteed disable, tie EN to GND. The EN threshold is 0.4V low and 2.0V high, allowing direct interface with 3.3V microcontroller GPIOs without external resistors.
Is a bypass capacitor required on the input pin?
Yes - a 1.0µF ceramic capacitor is required between VIN and GND, placed as close as possible to the device. This stabilizes the input impedance, suppresses high-frequency noise from upstream sources, and prevents oscillation during fast load transients, as validated in the datasheet's recommended application circuit.
Does the SOT89 package require special PCB layout considerations?
Yes - the exposed tab (pin 2) is electrically GND and thermally critical. It must be soldered to a minimum 100mm² copper pour with ≥4 thermal vias (0.3mm diameter) to an internal ground plane. Failure to do so degrades θJA from 118°C/W to >200°C/W, risking thermal shutdown under 100mA load at 85°C ambient.
