Product details
Overview
AP7361C-10Y5-13 from Diodes Incorporated is a 1A fixed-output (1.0V) ultra-low dropout linear regulator in SOT89-5 package with enable control, ±1% output accuracy, 360mV dropout at 1A (for 3.3V variant), and 60µA typical quiescent current-designed for power rail regulation in battery-powered audio/video systems and LCD-TVs.
For engineers reviewing the AP7361C-10Y5-13 datasheet, AP7361C-10Y5-13 pinout, AP7361C-10Y5-13 application, or AP7361C-10Y5-13 equivalent, key selection criteria include dropout voltage at 1A load, EN pin logic thresholds (VIH = 1.0V, VIL = 0.3V), thermal shutdown threshold (150°C), PSRR (75dB @ 1kHz), and compatibility with ≥2.2µF MLCC output capacitors.
Technical Context
The AP7361C-10Y5-13 integrates a PMOS pass element, band-gap reference, error amplifier, and thermal shutdown circuitry to deliver stable 1.0V output across –40°C to +85°C ambient. Its fold-back short-circuit protection limits output current to 400mA during fault conditions.
It operates within 2.2V–6.0V input range and maintains regulation down to 2.2V input for 1.0V output. The EN pin enables active-high control with 3.0MΩ internal pull-down resistor and ±0.1µA leakage, supporting low-power sequencing in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±1% - ensures precise core voltage for low-voltage logic rails |
| Max Output Current | 1.0A - supports moderate-power subsystems such as display bias or audio DAC supplies |
| Dropout Voltage | 710mV typ. at 300mA, 840mV typ. at 1A (for 1.0V output) - enables operation from single-cell Li-ion or 2-cell alkaline inputs |
| Quiescent Current | 60µA typ. - minimizes standby power loss in always-on system blocks |
| PSRR | 75dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input |
| Thermal Shutdown | 150°C threshold with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking |
| EN Logic Thresholds | VIL ≤ 0.3V, VIH ≥ 1.0V - compatible with 1.8V/3.3V GPIO without level-shifting |
Pinout & Package
SOT89-5 package with exposed thermal pad (pin 4 = GND); compact 4.5mm × 2.5mm footprint optimized for space-constrained consumer PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 2.2V–6.0V; requires ≥1µF ceramic bypass capacitor placed adjacent to pin |
| 2 (GND) | Power ground reference | Common return for input/output paths and thermal pad; must be low-impedance plane |
| 3 (OUT) | Regulated output | Delivers 1.0V ±1%; stable with ≥2.2µF MLCC; output discharge resistor (100Ω) aids fast turn-off |
| 5 (EN) | Enable control input | Active-high logic; internal 3.0MΩ pull-down allows default-off operation; VIH ≥ 1.0V ensures reliable turn-on from 1.8V I/O |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 840mV max at 1A for 1.0V output - extends usable input voltage range in brown-out conditions |
| Fold-back short-circuit protection | Clamps output to ~400mA during hard short - limits power dissipation and avoids thermal runaway |
| Stable with small MLCCs | Guaranteed stability with ≥2.2µF X5R/X7R ceramic output capacitor - eliminates need for bulky electrolytics |
| Low-ESR insensitive design | No minimum ESR requirement - simplifies capacitor selection and improves reliability over temperature |
| Green packaging | Halogen- and antimony-free, RoHS-compliant molding compound - meets global environmental compliance mandates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1002E/TT | 300mA max output, 170mV dropout at 250mA, no EN pin, SOT23-3 package | Limited to low-current peripherals; lacks enable control for power sequencing | Select when board space is critical and load < 300mA; not suitable for 1A loads or EN-driven wake-up |
| Torex XC6210B102MR-G | 1A output, 250mV dropout at 1A (for 1.0V), 25µA IQ, SOT25 package, no thermal shutdown | Lower dropout and IQ but missing thermal protection - requires external thermal monitoring | Prefer for ultra-low-power designs where thermal derating is managed externally; avoid in unventilated enclosures |
Compared with MCP1700T-1002E/TT and XC6210B102MR-G, the AP7361C-10Y5-13 uniquely combines 1A capability, integrated thermal shutdown, EN control, and SOT89-5 thermal performance-making it optimal for thermally constrained 1.0V rails where reliability under transient overload is mandatory.

FAQ
What is the minimum input voltage required for AP7361C-10Y5-13 to regulate 1.0V output?
The AP7361C-10Y5-13 requires VIN ≥ 2.2V to maintain regulation at 1.0V output, as specified in Recommended Operating Conditions. At 1A load, the dropout voltage is 840mV typ., so VIN must be ≥ 1.84V in practice-but 2.2V is the absolute minimum per datasheet to ensure stability across temperature and process variation.
Can AP7361C-10Y5-13 operate without an external output capacitor?
No. The AP7361C-10Y5-13 requires a minimum 2.2µF ceramic output capacitor between OUT and GND for stability, as confirmed in Application Information section. Omitting it risks oscillation, poor transient response, and potential thermal shutdown due to instability-induced power dissipation.
Is the EN pin internally pulled down, and what happens if left floating?
Yes-the EN pin has a 3.0MΩ internal pull-down resistor. If left floating, it will default to logic low, disabling the regulator output. For always-on operation, tie EN directly to IN; for controlled sequencing, drive it with a GPIO meeting VIH ≥ 1.0V and VIL ≤ 0.3V.
Does AP7361C-10Y5-13 support reverse current blocking?
No. The AP7361C-10Y5-13 uses a PMOS pass device but does not include reverse current blocking functionality. If VOUT exceeds VIN (e.g., during hot-swap or backup battery scenarios), current can flow backward from OUT to IN unless an external Schottky diode is added.
