Product details
Overview
AP7354-30FS4-7 from Diodes Incorporated is a fixed 3.0V, 150mA ultra-low quiescent current LDO regulator in X2-DFN1010-4 (Type B) package with ±1% output voltage accuracy, 0.25µA quiescent current, and integrated enable control - designed for power management in space-constrained, battery-operated IoT sensor modules and wearable electronics.
For engineers reviewing the AP7354-30FS4-7 datasheet, AP7354-30FS4-7 pinout, AP7354-30FS4-7 application, or AP7354-30FS4-7 equivalent, key selection criteria include dropout voltage at 150mA (0.18V typical), active output discharge capability (35Ω), thermal resistance (295°C/W), and compatibility with 0.1µF ceramic input/output capacitors.
Technical Context
The AP7354-30FS4-7 integrates a precision voltage reference, error amplifier, current-limit circuit, and logic-level enable input to support on/off control with 0.02µA standby current. Its architecture delivers stable regulation across 2.0V–5.5V input range while maintaining ±1% VOUT accuracy over -40°C to +85°C ambient.
It features built-in output discharge (enabled via EN low), supports fast load transient response (≤50µs recovery), and operates with minimal external components - requiring only 0.1µF CIN and COUT - due to internal compensation optimized for low-ESR ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% at 1mA, ensuring stable MCU core or sensor biasing without external feedback network. |
| Max Output Current | 150mA guaranteed, sufficient for powering BLE SoCs, image sensors, or low-power microcontrollers. |
| Quiescent Current | 0.25µA typical, enabling multi-year battery life in always-on environmental monitoring nodes. |
| Dropout Voltage | 0.18V typical at 150mA and 3.0V output, allowing operation down to 3.18V input - critical for single-cell Li-ion or coin-cell systems. |
| Enable Threshold | VEN(H) ≥1.0V, VEN(L) ≤0.4V - compatible with 1.8V/3.3V GPIOs without level-shifting. |
| Thermal Resistance | θJA = 295°C/W (X2-DFN1010-4), requiring minimal PCB copper area for thermal management in compact wearables. |
| ESD Protection | 4kV HBM, 400V MM - robust enough for handling during automated assembly and field-replaceable modules. |
Pinout & Package
X2-DFN1010-4 (Type B) is a 1.0mm × 1.0mm, 0.25mm profile, lead-free surface-mount package with exposed thermal pad (no electrical connection). It enables high-density placement in miniature PCBs and provides superior thermal performance vs. SOT23/SOT25 for same power dissipation.
| 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 for stability and transient response. |
| Pin 2 | GND | Power ground reference; requires low-impedance connection to PCB ground plane to minimize noise and dropout variation. |
| Pin 3 | EN | Active-high enable; drives regulator into shutdown (0.02µA IQ) when pulled low; must not float. |
| Pin 4 | VIN | Input supply (2.0–5.5V); requires local 0.1µF ceramic decoupling to suppress supply ripple and maintain PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 0.25µA typical enables >10-year battery life in 10µA average-load IoT endpoints. |
| Integrated output discharge | 35Ω active pull-down on VOUT during shutdown prevents residual voltage hold-up in multi-rail systems. |
| High accuracy over temperature | ±2% VOUT tolerance across -40°C to +85°C ensures reliable ADC reference or RF IC biasing without calibration. |
| Small-footprint packaging | X2-DFN1010-4 (1.0mm × 1.0mm) reduces board area by 75% vs. SOT25, critical for hearable and patch-style wearables. |
| Stable with minimal capacitance | Guaranteed stability with 0.1µF X5R/X7R ceramic CIN/COUT eliminates need for bulk capacitors or ESR tuning. |

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 | 3.0V fixed, 250mA, 1.6µA IQ, SOT23-5 package, no output discharge. | Larger footprint, higher quiescent current limits battery life in sub-µA sleep systems. | Select when board space permits larger package and discharge function is unnecessary. |
| Torex XC6210B302MR-G | 3.0V fixed, 150mA, 1.0µA IQ, USP-4 package (1.2×1.2mm), no discharge. | Slightly larger footprint than X2-DFN1010-4; lacks active discharge, requiring external MOSFET for rail sequencing. | Choose if prefer Torex's qualification pedigree for industrial temp range (-40°C to +105°C). |
Compared with MCP1700-3002E/TO and XC6210B302MR-G, AP7354-30FS4-7 offers the lowest quiescent current (0.25µA), smallest footprint (1.0mm²), and integrated discharge - making it optimal for miniaturized, long-life battery systems where rail sequencing and leakage control are critical.

FAQ
Is AP7354-30FS4-7 pin-compatible with other AP7354 variants?
No - AP7354-30FS4-7 uses the X2-DFN1010-4 (Type B) package with 4 pins in 1.0mm × 1.0mm layout, while SOT23 and SOT25 variants have different pin counts (3-pin vs. 5-pin) and footprints. Pin mapping differs: X2-DFN1010-4 assigns VOUT to Pin 1, GND to Pin 2, EN to Pin 3, and VIN to Pin 4 - incompatible with SOT23/SOT25 land patterns.
Does AP7354-30FS4-7 require an external discharge FET?
No - AP7354-30FS4-7 includes integrated active output discharge (35Ω typical resistance) that automatically pulls VOUT to GND when EN is low. This eliminates need for external MOSFET or resistor networks in systems requiring rapid rail collapse, such as multi-voltage domain power sequencing.
What is the minimum recommended input capacitor for AP7354-30FS4-7?
A 0.1µF X5R or X7R ceramic capacitor is the minimum recommended input capacitor, placed directly between VIN and GND pins. The datasheet specifies this value ensures stability and suppresses input supply glitches; larger values (e.g., 1µF) may improve PSRR but are not required for basic operation.
Can AP7354-30FS4-7 operate with input voltage below 2.0V?
No - the absolute minimum input voltage is 2.0V per Recommended Operating Conditions. Operation below this violates specification and risks regulation loss, increased dropout, or undefined behavior. At 3.0V output, the practical lower limit is ~3.18V due to 0.18V typical dropout at 150mA load.
