Product details
Overview
AP7350-25CF4-7 from Diodes Incorporated is a 2.5V fixed-output, 150mA ultra-low quiescent current LDO regulator in a wafer-level chip-scale X2-WLB0606-4 package. It delivers ±1% output voltage accuracy across -40°C to +85°C, features 0.25µA typical quiescent current, and supports input voltages from 2.0V to 5.25V - enabling long battery life in space-constrained wearable and IoT sensor modules.
For engineers reviewing the AP7350-25CF4-7 datasheet, AP7350-25CF4-7 pinout, AP7350-25CF4-7 application, or AP7350-25CF4-7 equivalent, key selection criteria include dropout voltage at 150mA (0.22V typ @ 2.5V), EN-controlled shutdown with 0.02µA standby current, thermal resistance (267°C/W), and compatibility with 0.1µF ceramic input/output capacitors.
Technical Context
The AP7350-25CF4-7 integrates a precision voltage reference, error amplifier, current-limit circuit, and enable logic in a monolithic CMOS process. Its architecture supports stable regulation down to 2.0V input while maintaining 2.5V output under full 150mA load, with dropout voltage scaling inversely with VOUT.
It operates without external discharge circuitry (non-AP7350D variant), relies on internal resistor network for fixed 2.5V output, and uses SnAgCu solderable micro-balls compatible with standard reflow profiles per MIL-STD-202 Method 208.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±1% at +25°C; ±2% over -40°C to +85°C - ensures stable MCU core or sensor bias supply |
| Max Output Current | 150mA continuous - sufficient for BLE SoCs, low-power image sensors, or multi-node IoT transceivers |
| Quiescent Current | 0.25µA typical - extends coin-cell battery life beyond 5 years in always-on wake-on-event applications |
| Dropout Voltage | 0.22V typ @ 150mA - allows operation from single Li-ion (3.0V min) or two alkaline cells (2.7V min) |
| Input Voltage Range | 2.0V to 5.25V - supports direct connection to USB VBUS, boost converter outputs, or multi-cell batteries |
| Enable Threshold | EN high ≥1.0V, low ≤0.4V - compatible with 1.8V/3.3V GPIO without level-shifting |
| Thermal Resistance | θJA = 267°C/W - requires minimal PCB copper area for thermal management in compact layouts |
Pinout & Package
The AP7350-25CF4-7 uses the X2-WLB0606-4 wafer-level chip-scale package (0.64mm × 0.64mm × 0.23mm), one of the smallest LDO footprints available, with four SnAgCu micro-balls arranged in a square configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable control input | Active-high logic input; must be driven to avoid floating; enables regulator when ≥1.0V, forces shutdown when ≤0.4V |
| 2 (GND) | Ground reference | Primary return path for input, output, and internal circuitry; connects directly to PCB ground plane for stability |
| 3 (VOUT) | Regulated output | Delivers stable 2.5V to load; requires 0.1µF ceramic capacitor placed adjacent to pin for transient response |
| 4 (VIN) | Power input | Accepts 2.0–5.25V input; requires 0.1µF decoupling capacitor close to pin to suppress supply noise and load-step transients |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 0.25µA typical enables >5-year battery life in always-on sensor nodes powered by CR2032 |
| Miniature WLCSP footprint | X2-WLB0606-4 (0.64mm²) reduces board area by >70% vs. SOT-23, critical for wearables and hearing aids |
| High output accuracy | ±1% at +25°C and ±2% over full temperature range ensures reliable ADC reference or RF biasing |
| Low dropout at full load | 0.22V typ @ 150mA allows use with aging batteries or low-headroom power rails |
| Integrated ESD protection | 4kV HBM / 400V MM rating eliminates need for external TVS in consumer-grade IoT end equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2502E/TO | TO-92 package (larger footprint), 1.6µA IQ, 250mA output | Higher IQ limits battery life; through-hole mounting incompatible with ultra-thin wearables | Select only if manual assembly or legacy TO-92 footprint required |
| Torex XC6219B251MR-G | USP-4 package (0.8mm × 0.8mm), 1µA IQ, 150mA output | Larger footprint (+25% area), no integrated ESD protection (requires external TVS) | Choose when higher ESD robustness is not needed and USP-4 is already standardized in design |
Compared with MCP1700-2502E/TO and XC6219B251MR-G, the AP7350-25CF4-7 uniquely combines sub-µA quiescent current, industry-smallest WLCSP footprint, and built-in 4kV HBM ESD protection - making it optimal for next-generation miniaturized, battery-critical edge devices where board space and longevity are non-negotiable.

FAQ
What is the minimum input voltage required for stable 2.5V output at 150mA?
The AP7350-25CF4-7 requires VIN ≥ 2.72V to maintain regulated 2.5V output at 150mA load, based on its typical 0.22V dropout voltage. At lower input voltages, output collapses linearly; operation below 2.0V is prohibited per absolute maximum ratings.
Can the EN pin be left unconnected if always-on operation is desired?
No - the EN pin must never float. For permanent enable, tie EN directly to VIN using a short PCB trace. Floating EN causes undefined output state and may increase leakage current or induce oscillation due to noise coupling into the high-impedance input.
Is an external discharge FET required for this part?
No - AP7350-25CF4-7 is the non-discharge variant (no "D" suffix). It lacks internal active discharge circuitry. If rapid VOUT decay after shutdown is required, select AP7350D-25CF4-7 (35Ω typical discharge resistance) or add external passive discharge.
What capacitor types and placement rules apply for stable operation?
Use X5R or X7R 0.1µF ceramic capacitors for both CIN and COUT, placed within 1mm of their respective pins. Avoid light exposure to the WLCSP die surface. Layout must minimize GND loop inductance using solid ground plane and wide traces for VIN/VOUT paths.
