Product details

Overview

AP7361C-10DR-13 from Diodes Incorporated is a 1A fixed-output (1.0V) ultra-low dropout linear regulator with enable, designed for power rail regulation in space-constrained, battery-sensitive systems. It delivers ±1% output accuracy, 360mV dropout at 1A (for 3.3V version), and 60µA quiescent current, supporting stable operation in LCD-TV, set-top-box, and home appliance power domains.

For engineers reviewing the AP7361C-10DR-13 datasheet, AP7361C-10DR-13 pinout, AP7361C-10DR-13 application, or AP7361C-10DR-13 equivalent, key selection criteria include dropout voltage at 1.0V output, EN pin logic thresholds (VIH = 1.0V min), thermal shutdown threshold (150°C), and compatibility with 2.2µF MLCC output capacitors without external compensation.

Technical Context

The AP7361C-10DR-13 integrates a PMOS pass element, band-gap reference, error amplifier, and fold-back current limiting. Its fixed 1.0V output is internally trimmed; no external resistors are required. The EN pin enables direct microcontroller-level control with 1.0V minimum VIH and 0.3V maximum VIL.

Thermal shutdown activates at 150°C junction temperature with 20°C hysteresis, and short-circuit protection limits output to 400mA during fault conditions. Stability is guaranteed with ≥2.2µF ceramic output capacitance across -40°C to +85°C ambient range.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.0V ±1% - ensures precise core logic or low-voltage I/O rail regulation without external feedback.
Max Output Current	1.0A continuous - supports moderate-power SoC or FPGA I/O banks with headroom for transient loads.
Dropout Voltage	710mV typ @ 300mA, 1.0V output - enables operation from 1.71V input (e.g., single LiFePO₄ cell or boosted 1.2V rail).
Quiescent Current	60µA typ - minimizes standby power loss in always-on subsystems like remote control receivers or sensor wake logic.
PSRR	75dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input.
Enable Threshold	VIH = 1.0V min, VIL = 0.3V max - compatible with 1.8V or 3.3V GPIO without level-shifting.
Thermal Shutdown	150°C activation with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking.
Output Capacitor	Stable with ≥2.2µF MLCC - eliminates need for bulky electrolytics; reduces board area and improves reliability.

Pinout & Package

AP7361C-10DR-13 uses the TO252 (DPAK)R package: 3-pin variant with Pin 1 = GND, Pin 2 = OUT, Pin 3 = IN. Exposed thermal pad on bottom enhances thermal performance (θJA = 95°C/W).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (GND)	Ground reference and thermal path	Must be connected to large copper pour for heat dissipation and low-noise return path.
Pin 2 (OUT)	Regulated 1.0V output	Requires ≥2.2µF ceramic capacitor placed adjacent to pin; trace length minimized to reduce ESR-induced ripple.
Pin 3 (IN)	Input supply (2.2–6.0V)	Needs ≥1µF ceramic bypass capacitor; wide trace recommended to handle 1A peak currents without IR drop.

Key Features

Feature	Design Value
Ultra-low IQ	60µA typical enables >1-year battery life in coin-cell-powered remote controls or IoT sensors.
Fold-back short-circuit protection	Clamps output to 400mA during hard shorts - prevents thermal runaway while allowing safe recovery when fault clears.
EN-controlled sequencing	Active-high enable allows synchronized power-up with system MCU or PMIC, avoiding race conditions in multi-rail designs.
Wide input range	2.2V to 6.0V input supports direct connection to Li-ion, LiPo, or buck converter outputs without pre-regulation.
Green packaging	Halogen- and antimony-free, RoHS-compliant construction meets IEC 61249-2-21 and automotive environmental requirements.

Applications

Use Scenario: Providing clean 1.0V supply to ARM Cortex-A53 CPU cores in 4K smart TV mainboards.

IC Role / Device Role / Timing Role: Primary low-noise post-regulator for processor core rail, decoupling high-frequency switching noise from upstream DC/DC.

Use Value: 75dB PSRR at 1kHz rejects noise from 1MHz buck converters, preventing digital jitter and video artifacts.

Use Scenario: Delivering stable 1.0V to HDMI PHY and audio codec ICs in cable/satellite STB platforms.

IC Role / Device Role / Timing Role: Dedicated LDO for interface I/O rails requiring tight voltage tolerance and fast load transient response.

Use Value: 200µs startup time enables rapid wake-from-sleep transitions, meeting <100ms HDMI hot-plug detection timing.

Home Appliance Control Panel

IoT Sensor Hub Power

Use Scenario: Regulating 1.0V for touch controller and display driver in microwave oven or washing machine UI modules.

IC Role / Device Role / Timing Role: Low-quiescent-current LDO powering always-on user interface circuitry during standby mode.

Use Value: 60µA IQ extends battery backup runtime beyond 5 years in non-replaceable CR2032-supplied panels.

Use Scenario: Generating 1.0V for ultra-low-power BLE SoC (e.g., nRF52840) in battery-operated environmental sensor nodes.

IC Role / Device Role / Timing Role: Main system LDO enabling deep-sleep current optimization and fast wake-up capability.

Use Value: Fold-back current limit protects against accidental short during field wiring, preserving node uptime in unattended deployments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-output LDO applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700-1002E/TO	300mA max output, 170mV dropout @ 250mA, 2.0µA IQ - lower current, much lower IQ, higher dropout at full load.	Suitable only for sub-300mA logic rails; insufficient for 1A SoC cores or motor drivers.	Select when ultra-low standby power dominates over output current capability.
TLC7601CDR	1.5A max output, 250mV dropout @ 1A, 120µA IQ - higher current, lower dropout, higher IQ, no EN pin.	Lacks enable control; requires external transistor for sequencing; better for high-current analog rails.	Select when sequencing is not required and 1.5A headroom justifies higher IQ and cost.

Compared with MCP1700-1002E/TO and TLC7601CDR, AP7361C-10DR-13 uniquely balances 1A delivery, 60µA IQ, EN control, and TO252R thermal performance-making it optimal for mid-power embedded systems needing both efficiency and controllability.

FAQ

What is the minimum input voltage required for AP7361C-10DR-13 to regulate 1.0V output at 1A?

The minimum input voltage is determined by dropout: at 1A, typical dropout is 840mV for 1.0V output, so VIN must be ≥1.84V. Absolute maximum rating allows up to 6.5V input, but recommended operating range is 2.2V–6.0V per datasheet specifications.

Can AP7361C-10DR-13 operate without an enable signal connected?

Yes - if EN is not used, it must be tied directly to IN to maintain regulation. Leaving EN floating is not permitted due to undefined logic state; internal 3.0MΩ pull-down resistor ensures safe default-off behavior only when explicitly grounded.

Is the TO252 (DPAK)R package thermally superior to standard TO252 for AP7361C-10DR-13?

Yes - TO252R (DR suffix) has reversed pinout (GND-OUT-IN) and optimized thermal pad layout, achieving θJA = 95°C/W versus 95°C/W for standard DPAK; both offer identical thermal resistance, but DR improves PCB routing flexibility in dense layouts.

Does AP7361C-10DR-13 require a minimum load current to maintain regulation stability?

No - the device remains stable and regulated down to zero load current. Unlike older LDOs, it does not require a minimum load resistor; this simplifies design in sleep-mode applications where downstream circuits may fully power down.
