Product details
Overview
AP7361EA-10SPR-13 from Diodes Incorporated is a 1A, fixed-output (1.0V), ultra-low dropout linear regulator with enable function in SO-8EPR package. It delivers ±1% output voltage accuracy, 360mV dropout at 1A (for 3.3V version; 1.0V version exhibits ~710mV at 300mA), and 68µA typical quiescent current. Designed for power rails in LCD TVs, set-top boxes, and home appliances requiring stable low-voltage biasing.
For engineers reviewing the AP7361EA-10SPR-13 datasheet, AP7361EA-10SPR-13 pinout, AP7361EA-10SPR-13 application, or AP7361EA-10SPR-13 equivalent, key selection criteria include dropout voltage at 1.0V output, EN logic thresholds (VIH = 1.0V min), thermal resistance (θJA = 100°C/W), and compatibility with ≥2.2µF MLCC output capacitors.
Technical Context
The AP7361EA-10SPR-13 integrates a PMOS pass element, precision 0.8V bandgap reference, error amplifier, and foldback current limiting. Its architecture enables stable regulation down to 1.0V output with input as low as 2.2V, supporting battery-powered systems where VIN may dip near VOUT.
Enable control is implemented via a high-threshold logic input (VIH ≥ 1.0V) with 3.0MΩ internal pull-down resistor; thermal shutdown activates at +150°C with 20°C hysteresis, and short-circuit protection clamps output to 400mA during fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±1% - ensures precise core/bias rail for low-voltage logic and analog circuitry. |
| Max Output Current | 1.0A continuous - supports moderate-power subsystems like HDMI interface ICs or audio DACs. |
| Dropout Voltage | 710mV at 300mA (1.0V output) - enables operation with minimal headroom, e.g., 1.8V input powering 1.0V rail. |
| Quiescent Current | 68µA typical - minimizes standby power loss in always-on consumer electronics modules. |
| PSRR | 75dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Thermal Shutdown | 150°C junction threshold - protects against sustained overload or poor PCB thermal design in enclosed enclosures. |
| EN Input Threshold | VIH ≥ 1.0V, VIL ≤ 0.3V - compatible with 1.8V/3.3V GPIO without level-shifting in host SoC designs. |
Pinout & Package
AP7361EA-10SPR-13 uses the SO-8EPR package: thermally enhanced 8-pin surface-mount with exposed pad (EP) for improved heat dissipation. The EP must be connected to GND or large copper pour for optimal thermal performance (θJA = 100°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Regulator input; requires ≥1µF ceramic bypass capacitor close to pin to suppress supply noise and ensure stability. |
| 2 | GND | Power ground reference; connects to system ground plane and EP thermal pad for low-impedance return path. |
| 3 | ADJ/NC | No connection in fixed 1.0V version; left floating - not used for feedback or configuration. |
| 4 | IN | Second input terminal; paralleled with Pin 1 to reduce trace inductance and improve high-frequency PSRR. |
| 5 | EN | Active-high enable; pulls up internally via 3.0MΩ resistor - tie to IN for always-on operation or drive from microcontroller GPIO. |
| 6 | OUT | Regulated 1.0V output; requires ≥2.2µF ceramic capacitor (low ESR) for transient response and stability. |
| 7 | NC | No connection; electrically isolated - no routing or soldering required. |
| 8 | GND | Secondary ground terminal; enhances current handling and reduces ground bounce under dynamic load steps. |
| EP | Exposed Pad | Thermal interface only - connect to large GND copper area with multiple vias to inner layers for effective heat transfer. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 710mV at 300mA for 1.0V output enables use with Li-ion single-cell (3.0–3.6V) or dual-cell NiMH (2.4–2.8V) inputs. |
| Foldback short-circuit protection | Limits fault current to 400mA - prevents thermal runaway while allowing safe recovery when short is removed. |
| Stable with low-ESR capacitors | Works with MLCC, solid polymer, or tantalum ≥2.2µF - eliminates need for external compensation networks. |
| Low quiescent current | 68µA typical across 2.2–6.0V input range - extends battery life in standby modes of remote controls or IoT sensors. |
| High PSRR | 75dB @ 1kHz - maintains clean 1.0V rail despite ripple from switching regulators in multi-rail power architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-1002E/MB | 150mA max output, 600mV dropout at 100mA, SOT-23-5 package | Lower current capacity; suited for sensor nodes or low-power peripherals, not core logic rails | Select when board space is constrained and load <150mA; avoid for processor or memory rails. |
| TLS850B2TE/V1 | Automotive-grade AEC-Q100 qualified, 500mA, integrated watchdog and reset functions | Designed for automotive body electronics; includes fail-safe monitoring not present in AP7361EA | Choose for automotive infotainment or ADAS modules requiring functional safety features. |
Compared with MCP1703T-1002E/MB and TLS850B2TE/V1, the AP7361EA-10SPR-13 provides higher output current (1.0A vs. 150mA/500mA) and lower dropout at full load, making it suitable for demanding consumer electronics power rails where thermal management via SO-8EPR's exposed pad is feasible.

FAQ
What is the minimum input voltage required for AP7361EA-10SPR-13 to regulate 1.0V output?
The device requires VIN ≥ 2.2V per datasheet specifications. At 1.0V output, dropout is 710mV at 300mA, meaning VIN must be ≥1.71V under that load - but the absolute minimum input is 2.2V to guarantee full functionality across temperature and process variation. Below 2.2V, regulation is not guaranteed.
Can AP7361EA-10SPR-13 operate without an external output capacitor?
No. A minimum 2.2µF ceramic capacitor is required on the OUT pin for stability and transient response. Omitting it causes oscillation and potential damage. The datasheet explicitly states stability is ensured only with ≥2.2µF MLCC, E-Cap, Tan-Cap, or solid capacitor - no operation is specified without it.
How does the EN pin behave if left unconnected?
The EN pin has an internal 3.0MΩ pull-down resistor, so it defaults to logic-low when floating, disabling the regulator output. To ensure reliable startup, EN must be actively driven high (≥1.0V) or tied directly to IN. Leaving it open results in no output voltage.
Is the SO-8EPR package RoHS-compliant and halogen-free?
Yes. AP7361EA-10SPR-13 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen- and antimony-free per Diodes' "Green" definition: Br < 900ppm, Cl < 900ppm (Br+Cl < 1500ppm), Sb < 1000ppm. This is confirmed in the datasheet Notes 1–3 and Diodes' quality documentation.
