Product details
Overview
AP7350-30CF4-7 from Diodes Incorporated is a 3.0V fixed-output, 150mA ultra-low quiescent current LDO regulator in X2-WLB0606-4 wafer-level chip-scale package. It delivers ±1% output voltage accuracy over -40°C to +85°C, features 0.25µA typical quiescent current and 0.02µA standby current, and supports 2.0V–5.25V input range - optimized for battery-powered wearable electronics and IoT sensor modules.
For engineers reviewing the AP7350-30CF4-7 datasheet, AP7350-30CF4-7 pinout, AP7350-30CF4-7 application, or AP7350-30CF4-7 equivalent, key selection criteria include dropout voltage at 150mA (0.18V typ), EN-controlled shutdown, minimal board footprint (0.64mm × 0.64mm), and guaranteed stability with 0.1µF ceramic output capacitance.
Technical Context
The AP7350-30CF4-7 integrates a precision voltage reference, error amplifier, current-limit circuit, and enable logic in a single die. Its architecture supports fast load transient response (e.g., <10µs recovery for 1→50mA step at VOUT=3.3V) and maintains regulation down to 2.0V input while delivering 3.0V output.
It operates without external discharge circuitry (non-discharge variant), uses SnAgCu solderable micro-balls, and meets JESD 22 ESD ratings (4kV HBM, 400V MM). Thermal resistance θJA is 267°C/W on JEDEC-compliant PCB, enabling operation up to +85°C ambient with 150mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% at +25°C; ±2% over full temperature range - ensures stable MCU core or sensor biasing without external feedback. |
| Max Output Current | 150mA continuous - sufficient to power BLE SoCs, low-power image sensors, or multi-node IoT transceivers. |
| Quiescent Current | 0.25µA typical - extends battery life in always-on wearables (e.g., >1 year on CR2032 with 10µA avg load). |
| Dropout Voltage | 0.18V typical at 150mA - enables operation from single-cell Li-ion (3.0V min) or alkaline (3.2V fresh) without brownout. |
| Input Voltage Range | 2.0V to 5.25V - compatible with wide-range energy harvesting sources and multi-chemistry battery inputs. |
| Enable Threshold | EN high ≥1.0V, low ≤0.4V - interfaces directly with 1.8V/3.3V GPIO without level-shifting. |
| Package | X2-WLB0606-4 (0.64mm × 0.64mm, 0.34mm height) - smallest industry-standard LDO footprint, saving >60% area vs. SOT-23. |
Pinout & Package
AP7350-30CF4-7 uses the X2-WLB0606-4 wafer-level chip-scale package with four solder balls arranged in a 2×2 array. The package has no leads; terminals are SnAgCu micro-balls compatible with standard reflow profiles per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable control input | Active-high logic input; must be driven to VIN or GND - floating state disables regulation and risks undefined behavior. |
| 2 (GND) | Power ground reference | Primary return path for input/output current; requires low-impedance connection to PCB ground plane for stability. |
| 3 (VOUT) | Regulated output node | Delivers stable 3.0V; requires 0.1µF ceramic capacitor placed within 1mm of this ball and GND for transient immunity. |
| 4 (VIN) | Unregulated input supply | Accepts 2.0–5.25V; requires 0.1µF decoupling capacitor adjacent to this ball to suppress supply noise and load-step droop. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 0.25µA typical - reduces no-load battery drain to negligible levels in sleep-mode sensor nodes. |
| High output accuracy | ±1% at +25°C, ±2% over -40°C to +85°C - eliminates need for post-regulation trimming in precision analog front-ends. |
| Miniature WLCSP footprint | 0.64mm × 0.64mm - enables integration into space-constrained wearables (e.g., smart rings, hearables) where SOT-23 is prohibitive. |
| Robust ESD protection | 4kV HBM, 400V MM - withstands handling and board assembly without additional protection components. |
| Stable with 0.1µF ceramic COUT | No minimum ESR requirement - simplifies BOM by eliminating bulk tantalum or polymer capacitors. |
Applications
| Wearable Fitness Tracker | IoT Environmental Sensor Node |

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, TO-92 package (4.7mm × 3.7mm) | Larger footprint, higher quiescent current - suitable only when board space is unconstrained and battery life >6 months is acceptable. | Select if through-hole assembly or legacy TO-92 compatibility is required; avoid for wearables due to size and IQ penalty. |
| Torex XC6210B302MR-G | 3.0V fixed, 150mA, 1.0µA IQ, USP-4 package (1.2mm × 1.6mm) | USP-4 is 3× larger than X2-WLB0606-4; 4× higher IQ erodes battery life in sub-µA sleep systems. | Choose only if existing USP-4 footprint reuse is mandatory; not recommended for new ultra-compact designs. |
Compared with MCP1700-3002E/TO and XC6210B302MR-G, AP7350-30CF4-7 provides the smallest footprint and lowest quiescent current among 3.0V/150mA LDOs, making it uniquely suited for next-generation miniaturized battery-operated devices where board area and multi-year runtime are design-critical.

FAQ
What is the minimum input voltage required for AP7350-30CF4-7 to maintain 3.0V output at 150mA?
The minimum input voltage is determined by dropout voltage: at 150mA, typical dropout is 0.18V, so VIN must be ≥3.18V to sustain regulation. Absolute minimum VIN per datasheet is 2.0V, but output drops below 3.0V when VIN falls below VOUT + VDROPOUT.
Can AP7350-30CF4-7 be used without an external output capacitor?
No. An output capacitor (minimum 0.1µF ceramic) is mandatory for stability and transient response. Omitting COUT causes oscillation and voltage overshoot during load steps, as confirmed in the datasheet's Application Information section and stability graphs.
Is the EN pin internally pulled up or down?
The EN pin has no internal pull-up or pull-down. It must be actively driven high (≥1.0V) to enable regulation or low (≤0.4V) to enter shutdown. Leaving EN floating results in undefined output state and violates Absolute Maximum Ratings.
Does AP7350-30CF4-7 include output discharge functionality?
No. AP7350-30CF4-7 is the non-discharge variant (per ordering code "CF4" without "D" suffix). It lacks active output discharge; VOUT decays only through load and parasitic paths. For rapid VOUT discharge, select AP7350D-30CF4-7 (with built-in 35Ω discharge switch).
