Product details
Overview
AP7361EA-12Y5-13 from Diodes Incorporated is a 1A fixed-output (1.2V) ultra-low dropout linear regulator in SOT89-5 package with enable input, ±1% output accuracy, 360mV dropout at 1A (for 3.3V version), and 68µA typical quiescent current-designed for power rails in LCD TVs, set-top boxes, and battery-powered audio/video equipment.
For engineers reviewing the AP7361EA-12Y5-13 datasheet, AP7361EA-12Y5-13 pinout, AP7361EA-12Y5-13 application, or AP7361EA-12Y5-13 equivalent, key selection criteria include dropout voltage at 1.2V load, EN logic thresholds, thermal resistance (θJA = 150°C/W), stability with ≥2.2µF MLCC output capacitors, and foldback short-circuit protection (400mA).
Technical Context
The AP7361EA-12Y5-13 integrates a PMOS pass element, precision 0.8V bandgap reference, error amplifier, and thermal shutdown circuitry. Its fixed 1.2V output eliminates external resistor divider requirements while maintaining adjustable-mode compatibility via ADJ/NC pin.
Enable functionality operates with VIH ≥ 1.0V and VIL ≤ 0.3V, supporting direct microcontroller GPIO control. Foldback current limiting reduces power dissipation during short-circuit events, and thermal shutdown activates at ~150°C with 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±1% - ensures stable core voltage for low-power SoCs and FPGAs without external feedback components. |
| Max Output Current | 1.0A - supports moderate-power digital loads such as HDMI interface ICs or display timing controllers. |
| Dropout Voltage | ≤500mV at 1A (1.2V output) - enables operation from 1.7V input, critical for single-cell Li-ion or Li-poly battery systems. |
| Quiescent Current | 68µA typical - minimizes standby power loss in always-on subsystems like remote control receivers or real-time clocks. |
| 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 thermal design. |
| Input Voltage Range | 2.2V to 6.0V - compatible with 3.3V, 5V, and wide-input buck converter outputs. |
Pinout & Package
AP7361EA-12Y5-13 uses the SOT89-5 package (5-pin, surface-mount), featuring exposed thermal pad connected internally to GND. The package delivers θJA = 150°C/W under standard JEDEC test conditions, requiring minimum copper area on PCB for thermal reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Regulator input - must be bypassed with ≥1µF ceramic capacitor close to pin; accepts 2.2–6.0V supply. |
| 2 | GND | Power ground reference - connects to PCB ground plane; shares thermal pad connection in SOT89-5. |
| 3 | OUT | Regulated 1.2V output - requires ≥2.2µF MLCC for stability; supports up to 1A continuous load. |
| 4 | EN | Active-high enable - drives high (>1.0V) to activate regulator; pulls low (<0.3V) to enter shutdown (ISHDN ≤ 0.05µA). |
| 5 | ADJ/NC | No-connect for fixed 1.2V version - left floating or tied to GND; unused in this configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 360mV typical at 1A (3.3V variant); ≤500mV at 1A for 1.2V output - extends usable input range in battery-depleted conditions. |
| Foldback short-circuit protection | Limits output to ~400mA during hard shorts - reduces thermal stress and avoids catastrophic failure during board-level faults. |
| Stable with low-ESR capacitors | Works reliably with ≥2.2µF MLCC, tantalum, or polymer capacitors - eliminates need for high-ESR electrolytics and simplifies layout. |
| Low temperature coefficient | ±100ppm/°C output drift - maintains tight regulation across -40°C to +85°C ambient, suitable for consumer and industrial environments. |
| Green RoHS compliance | Totally lead-free, halogen- and antimony-free - meets IEC 61249-2-21 and EU Directive 2015/863/EU requirements. |

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-1202E/TT (Microchip) | 250mA max output, 6µA IQ, SOT23-3 package - no enable pin, lower current capability. | Suitable only for ultra-low-power MCU cores; cannot support 1A loads like AP7361EA-12Y5-13. | Select when IQ < 10µA is mandatory and load current ≤ 250mA. |
| Torex XC6210B122MR-G (Torex) | 1A output, 1.2V fixed, SOT23-5 package, 80µA IQ, but no thermal shutdown or foldback protection. | Lacks integrated thermal and short-circuit protection - requires external monitoring or derating in thermally constrained designs. | Select when board space is critical (SOT23-5 vs SOT89-5) and thermal margin is guaranteed. |
Compared with MCP1700T-1202E/TT and XC6210B122MR-G, AP7361EA-12Y5-13 uniquely combines 1A capability, enable control, foldback short-circuit protection, and thermal shutdown in a thermally enhanced SOT89-5 package-making it optimal for mid-power consumer electronics where reliability and fault tolerance are essential.

FAQ
What is the maximum input voltage for AP7361EA-12Y5-13?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2.2V to 6.0V. Exceeding 6.0V risks violating safe operating area limits and may trigger internal protection circuits. For reliable long-term operation, maintain VIN ≤ 6.0V with appropriate derating based on ambient temperature and power dissipation.
Can AP7361EA-12Y5-13 operate without an output capacitor?
No. A minimum 2.2µF ceramic output capacitor is required for stability across the full -40°C to +85°C temperature range. Omitting it causes oscillation and unregulated output. The device is optimized for MLCCs but also supports tantalum and polymer capacitors with ESR ≤ 100mΩ.
Is the EN pin internally pulled down?
No. The EN pin has no internal pull-down; it features a 3.0MΩ internal pull-down resistor (RENPD). This ensures default-off behavior if left unconnected, but for robust operation, tie EN directly to IN or drive actively from a GPIO to avoid noise-induced toggling in noisy environments.
Does AP7361EA-12Y5-13 support adjustable output voltages?
No. The "-12" suffix denotes a factory-trimmed fixed 1.2V output. While the ADJ/NC pin exists on the SOT89-5 package, it is not functional in this variant-the internal feedback network is permanently configured for 1.2V. Adjustable versions use "ADJ" in the ordering code (e.g., AP7361EA-ADJY5-13).
