Product details
Overview
AP7350D-15CF4-7 from Diodes Incorporated is a 1.5V 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 across -40°C to +85°C, supports input voltages from 2.0V to 5.25V, and draws only 0.25µA typical quiescent current - enabling multi-year battery life in compact wearable sensors and IoT edge nodes.
For engineers reviewing the AP7350D-15CF4-7 datasheet, AP7350D-15CF4-7 pinout, AP7350D-15CF4-7 application, or AP7350D-15CF4-7 equivalent, key selection criteria include its 0.25µA IQ, 1.5V ±1% accuracy, EN-controlled shutdown with 0.02µA standby current, and integrated active discharge for rapid VOUT decay - critical for power sequencing in space-constrained, battery-powered systems.
Technical Context
The AP7350D-15CF4-7 integrates a precision voltage reference, error amplifier, current-limit protection, and enable-controlled MOSFET pass element. Its architecture includes an internal active discharge path (35Ω typical) activated when EN is low, ensuring fast VOUT collapse to prevent back-powering downstream circuitry.
Designed for minimal board footprint, it operates across 2.0V–5.25V input range with dropout as low as 0.43V at 150mA (VOUT = 1.5V), and maintains stability with only 0.1µF ceramic input/output capacitors - eliminating need for external compensation or large bulk capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±1% (±2% over full temperature range) - ensures stable core voltage for low-power MCUs and sensors without external feedback. |
| Quiescent Current | 0.25µA typical at TA = +25°C - extends battery life in always-on wearables and remote sensor nodes. |
| Standby Current | 0.02µA typical with EN low - enables deep-sleep modes with negligible leakage during system hibernation. |
| Dropout Voltage | 0.43V max at 150mA (VOUT = 1.5V) - allows operation from single-cell Li-ion (3.0V min) or two-cell alkaline (2.4V min) with margin. |
| Active Discharge Resistance | 35Ω typical - discharges 1.5V output to <0.1V within ~1ms under 1µF load, preventing latch-up in hot-swap or reset scenarios. |
| ESD Protection | 4kV HBM, 400V MM - meets industrial I/O robustness requirements without external TVS diodes. |
| Thermal Resistance θJA | 267°C/W (X2-WLB0606-4 on JEDEC PCB) - supports 150mA continuous output up to +85°C ambient with no derating below +40°C. |
Pinout & Package
AP7350D-15CF4-7 uses the X2-WLB0606-4 wafer-level chip-scale package (0.64mm × 0.64mm × 0.23mm, 0.35mm ball pitch), featuring SnAgCu solderable micro-balls and Level 1 moisture sensitivity.
| 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 directly to low-impedance ground plane. |
| 3 (VOUT) | Regulated output | Delivers stable 1.5V to load; includes active discharge path to GND when EN = low. |
| 4 (VIN) | Input power supply | Accepts 2.0V–5.25V; requires 0.1µF ceramic capacitor placed adjacent to pin for transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 0.25µA typical - reduces battery drain by >90% vs. standard LDOs, enabling >5-year operation on CR2032 in intermittent-sensing applications. |
| Integrated active output discharge | 35Ω discharge path - eliminates need for external pull-down resistor, saving PCB area and BOM cost in reset-critical designs. |
| High accuracy over temperature | ±1% at +25°C, ±2% over -40°C to +85°C - avoids calibration overhead in precision analog front-ends and ADC reference supplies. |
| Miniature WLCSP footprint | 0.64mm × 0.64mm - fits within 1.0mm² board area, ideal for hearing aids, smart patches, and miniaturized IoT modules. |
| Stable with 0.1µF ceramics | No external compensation required - simplifies layout and eliminates ESR dependency issues common in larger-capacitor LDOs. |

FAQ
What is the minimum input voltage required for AP7350D-15CF4-7 to regulate 1.5V output at 150mA?
The minimum input voltage is determined by dropout: at 150mA and VOUT = 1.5V, max dropout is 0.43V, so VIN must be ≥ 1.93V. The device specifies 2.0V min operating input, providing 70mV margin for line regulation and PCB trace drop - ensuring reliable regulation across all conditions.
Does AP7350D-15CF4-7 require external capacitors, and what type is recommended?
Yes - a 0.1µF X5R/X7R ceramic capacitor is required between VIN and GND, and another 0.1µF between VOUT and GND. These must be placed within 1mm of their respective pins. Larger low-ESR bulk capacitors may be added for high-transient loads, but the LDO remains stable with only the minimum 0.1µF ceramics.
How does the active discharge function operate, and when is it engaged?
Active discharge engages automatically when EN is pulled low (<0.4V). An internal 35Ω switch connects VOUT to GND, discharging a 1µF load from 1.5V to <0.1V in ~1ms. This prevents back-powering, ensures clean reset sequencing, and eliminates need for external discharge resistors in space-sensitive designs.
Is AP7350D-15CF4-7 qualified for automotive applications?
No - AP7350D-15CF4-7 is not AEC-Q100 qualified. Diodes Incorporated offers automotive-grade variants (e.g., AP7350Q series) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. For automotive use, contact Diodes' automotive sales team for qualified alternatives.
