Product details
Overview
AP7350D-27CF4-7 from Diodes Incorporated is a 2.7V fixed-output, 150mA ultra-low quiescent current LDO regulator with active output discharge, housed in the X2-WLB0606-4 wafer-level chip-scale package. It delivers ±1% output voltage accuracy over temperature, supports 2.0V–5.25V input range, and draws only 0.25µA typical quiescent current - enabling multi-year battery life in compact wearable and IoT sensor modules.
For engineers reviewing the AP7350D-27CF4-7 datasheet, AP7350D-27CF4-7 pinout, AP7350D-27CF4-7 application, or AP7350D-27CF4-7 equivalent, key selection criteria include its 0.21V dropout at 150mA (2.7V output), EN-controlled shutdown with 0.02µA standby current, and integrated discharge path for rapid VOUT decay - critical for power sequencing in space-constrained, low-power edge devices.
Technical Context
The AP7350D-27CF4-7 integrates a precision voltage reference, error amplifier, current-limit protection, and enable-controlled pass transistor in a monolithic CMOS design. Its active output discharge circuit (35Ω typical) pulls VOUT to GND when EN is low, eliminating external discharge components and preventing back-powering of downstream circuitry.
It operates across –40°C to +85°C ambient, maintains stability with 0.1µF ceramic CIN/COUT, and achieves <0.1%/V line regulation and ±25mV load regulation (1–150mA). The X2-WLB0606-4 package (0.64mm × 0.64mm × 0.23mm) enables direct die attachment on PCBs with SnAgCu solder balls compliant to MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V ±1% at +25°C; ±2% over –40°C to +85°C - ensures stable MCU core or sensor bias under thermal variation. |
| Max Output Current | 150mA continuous - sufficient to power BLE SoCs, MEMS sensors, or low-power microcontrollers without thermal derating in X2-WLB0606-4. |
| Quiescent Current | 0.25µA typical - extends coin-cell battery life beyond 5 years in always-on wake-on-event applications. |
| Dropout Voltage | 0.21V at 150mA (2.7V output) - allows operation down to 2.91V input, maximizing usable battery voltage range. |
| EN Threshold | High: ≥1.0V; Low: ≤0.4V - compatible with 1.8V/3.3V GPIO without level-shifting. |
| Active Discharge | 35Ω typical resistance - discharges 10µF load in <350µs, meeting fast-power-down requirements in portable medical monitors. |
| ESD Rating | 4kV HBM, 400V MM - survives handling and board assembly without additional protection circuitry. |
Pinout & Package
AP7350D-27CF4-7 uses the X2-WLB0606-4 wafer-level chip-scale package (0.64mm × 0.64mm × 0.23mm, 4-ball array), with SnAgCu solderable terminals and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable control input | Logic-high (>1.0V) enables regulation; logic-low (<0.4V) disables output and activates internal discharge path. |
| 2 (GND) | Ground reference | Primary return path for input, output, and internal circuitry; must connect to low-impedance system ground plane. |
| 3 (VOUT) | Regulated output | Delivers stable 2.7V to load; includes active discharge to GND when EN = low. |
| 4 (VIN) | Input power supply | Accepts 2.0V–5.25V; requires 0.1µF ceramic decoupling capacitor placed adjacent to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 0.25µA typical - reduces no-load power loss to <1nW, enabling decade-scale battery operation in IoT endpoints. |
| Integrated discharge | 35Ω active pull-down - eliminates need for external MOSFET/resistor network, saving 0.5mm² PCB area. |
| Miniature WLCSP | 0.64mm × 0.64mm footprint - fits within camera module bezels and hearable device battery cavities. |
| ±1% output accuracy | Guaranteed at +25°C - ensures reliable brown-out detection thresholds for 2.7V-tolerant microcontrollers. |
| Wide VIN range | 2.0V–5.25V - supports single-cell Li-ion (2.7–4.2V), alkaline (up to 3×), and USB-powered designs. |

FAQ
What is the minimum input voltage required for AP7350D-27CF4-7 to maintain regulation at full 150mA load?
The minimum input voltage is calculated as VOUT + VDROPOUT = 2.7V + 0.21V = 2.91V. At 150mA load and +25°C, the device sustains regulation down to 2.91V input; at –40°C to +85°C, worst-case dropout is 0.44V, requiring ≥3.14V input for full-load operation.
Can AP7350D-27CF4-7 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 output voltage overshoot during load steps, as confirmed in the datasheet's Application Information section and stability graphs.
How does the active discharge function behave during EN pin transition?
When EN transitions from high to low, the internal discharge switch turns on within 1µs (typical), pulling VOUT toward GND through a 35Ω path. Discharge completes when VOUT falls below ~0.1V, ensuring no residual voltage remains to interfere with subsequent power-up sequencing.
Is AP7350D-27CF4-7 qualified for automotive applications?
No. This part is not AEC-Q100 qualified and is intended for commercial/industrial use only. Diodes Incorporated offers automotive-grade variants (e.g., AP7350Q series) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening - contact their automotive team for qualified alternatives.
