Product details
Overview
AP7354D-30FS4-7 from Diodes Incorporated is a 3.0V fixed-output, 150mA ultra-low quiescent current LDO regulator in X2-DFN1010-4 (Type B) package with integrated active output discharge, ±1% output voltage accuracy over temperature, and 0.25µA quiescent current at zero load - designed for battery-powered wearable sensors and IoT edge nodes requiring extended runtime.
For engineers reviewing the AP7354D-30FS4-7 datasheet, AP7354D-30FS4-7 pinout, AP7354D-30FS4-7 application, or AP7354D-30FS4-7 equivalent, key selection criteria include discharge-enabled shutdown behavior, 0.14V dropout at 150mA/3.0V output, thermal resistance of 295°C/W in DFN, and compatibility with 0.1µF ceramic input/output capacitors.
Technical Context
The AP7354D-30FS4-7 implements a PMOS pass transistor architecture with internal voltage reference, error amplifier, and current-limit protection. Its enable-controlled shutdown achieves 0.02µA standby current, and the built-in active discharge path (35Ω typical) rapidly collapses VOUT when EN is pulled low.
This variant supports 2.0V–5.5V input range and delivers stable 3.0V output across –40°C to +85°C ambient, with line regulation of 0.02%/V and load regulation of ±40mV from 1mA to 150mA - enabling direct replacement of legacy LDOs in space-constrained, low-power sensor rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% at +25°C; ±2% over –40°C to +85°C - ensures stable MCU core or RF transceiver supply without external feedback. |
| Max Output Current | 150mA continuous - sufficient to power BLE SoCs, MEMS sensors, or low-power microcontrollers. |
| Quiescent Current | 0.25µA typical at no load - extends coin-cell or Li-ion battery life by minimizing idle drain. |
| Dropout Voltage | 0.14V typical at 150mA/3.0V output - enables operation down to 3.14V input, critical for aging battery systems. |
| Enable Threshold | EN high = ≥1.0V; EN low = ≤0.4V - compatible with 1.8V/3.3V GPIO without level-shifting. |
| Active Discharge | 35Ω typical pull-down resistance on VOUT during shutdown - prevents floating bias in downstream circuitry. |
| Thermal Resistance | 295°C/W junction-to-ambient (θJA) in X2-DFN1010-4 - requires minimal PCB copper area for thermal management. |
Pinout & Package
X2-DFN1010-4 (Type B) package: 1.0mm × 1.0mm footprint, 0.25mm nominal height, NiPdAu-plated copper terminals, moisture sensitivity level 1, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | VOUT | Regulated 3.0V output - must be decoupled with 0.1µF ceramic capacitor placed adjacent to pin. |
| Pin 2 | GND | Power ground reference - connects directly to PCB ground plane; center pad is not electrically connected. |
| Pin 3 | EN | Active-high enable - drives regulator ON/OFF; must not float; tied to VIN if always-on operation required. |
| Pin 4 | VIN | Input supply (2.0–5.5V) - requires local 0.1µF ceramic decoupling capacitor between VIN and GND. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 0.25µA enables >10-year battery life in always-on environmental sensors using CR2032 cells. |
| Integrated active output discharge | 35Ω discharge path eliminates need for external pulldown resistor in power sequencing-critical applications. |
| High accuracy over temperature | ±1% at +25°C and ±2% over full –40°C to +85°C range ensures reliable ADC reference or PLL supply stability. |
| Small-footprint DFN package | 1.0mm × 1.0mm X2-DFN1010-4 reduces PCB area by 70% vs. SOT25 while maintaining thermal performance. |
| Robust ESD protection | 4kV HBM and 400V MM rating allows safe handling in low-ESD-control assembly environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3002E/TO | No active discharge; 1.6µA quiescent current; TO-92 package (larger footprint). | Lacks fast VOUT collapse; unsuitable for strict power sequencing or multi-rail shutdown coordination. | Select only if board space and discharge function are non-critical and TO-92 mounting is preferred. |
| Torex XC6210B302MR-G | 0.6µA IQ; no discharge; SOT-25 package; 200mA rating. | Higher quiescent current reduces battery life; larger SOT-25 footprint increases PCB area. | Choose when higher output current margin is needed and discharge is handled externally. |
Compared with MCP1700-3002E/TO and XC6210B302MR-G, the AP7354D-30FS4-7 uniquely combines ultra-low 0.25µA IQ, integrated 35Ω discharge, and 1.0mm² DFN packaging - making it optimal for miniaturized, battery-sensitive designs where both runtime and controlled shutdown matter.

FAQ
What is the minimum input voltage required for AP7354D-30FS4-7 to maintain regulated 3.0V output at 150mA?
The dropout voltage is 0.14V typical at 150mA and 3.0V output, so minimum input is 3.0V + 0.14V = 3.14V. At worst-case (0.35V max dropout), VIN must be ≥3.35V to sustain regulation under full load and temperature extremes.
Can the EN pin be left unconnected if always-on operation is desired?
No - the EN pin must never be left floating. For permanent enable, connect EN directly to VIN. Floating EN risks undefined regulator state, increased leakage, or erratic startup due to noise coupling on the high-impedance input.
Does the X2-DFN1010-4 (Type B) package require solder paste on the center pad?
No - the center pad is electrically isolated and has no internal connection. Diodes' datasheet explicitly states "No connection or ground" for the center pad; soldering it provides no electrical benefit and may cause solder bridging or warpage.
How does the active output discharge behave during EN-driven shutdown?
When EN is pulled low, the internal 35Ω discharge FET connects VOUT to GND, collapsing output voltage within microseconds. This prevents back-powering of upstream sources or unintended biasing of downstream components like I²C pull-ups or analog inputs.
