Product details
Overview
AP7350D-12CF4-7 from Diodes Incorporated is a 150mA ultra-low quiescent current (0.25µA typ) LDO regulator with fixed 1.2V output, enable control, and active output discharge functionality, housed in the X2-WLB0606-4 wafer-level chip-scale package. It delivers ±1% output voltage accuracy across -40°C to +85°C and supports input voltages from 2.0V to 5.25V, making it ideal for space-constrained, battery-powered wearable electronics and IoT sensor modules.
For engineers reviewing the AP7350D-12CF4-7 datasheet, AP7350D-12CF4-7 pinout, AP7350D-12CF4-7 application, or AP7350D-12CF4-7 equivalent, key selection criteria include its 0.02µA standby current, 0.60V dropout at 150mA/1.2V, EN-controlled shutdown, integrated discharge path (35Ω typical), and compatibility with 0.1µF ceramic input/output capacitors.
Technical Context
The AP7350D integrates a precision voltage reference, error amplifier, current-limit circuit, and active output discharge transistor-enabling fast turn-off with controlled VOUT decay. Its architecture supports stable regulation under light-load conditions where quiescent current dominates system power budget.
Designed for ultra-low-power systems, it operates across a wide VIN range (2.0–5.25V) while maintaining tight load/line regulation (±25mV max load variation, 0.1%/V line regulation) and robust ESD protection (4kV HBM, 400V MM), all within a 0.64mm × 0.64mm footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±1% at +25°C; ±2% over full temperature range - ensures stable core voltage for low-power MCUs and sensors. |
| Quiescent Current | 0.25µA typical at IOUT = 0mA - minimizes battery drain during sleep modes in wearables and remote sensors. |
| Standby Current | 0.02µA typical when EN = low - enables near-zero power state for long-term storage or deep-sleep operation. |
| Dropout Voltage | 0.60V max at 150mA/1.2V output - allows operation from single-cell Li-ion (3.0V min) or two-cell alkaline (2.4V min) sources. |
| EN Threshold | VIH ≥ 1.0V, VIL ≤ 0.4V - compatible with 1.8V/3.3V GPIO without level-shifting in modern microcontrollers. |
| Active Discharge | 35Ω typical resistance between VOUT and GND when disabled - prevents floating output and speeds up power-down sequencing. |
| Thermal Resistance | θJA = 267°C/W (X2-WLB0606-4 on JEDEC PCB) - limits junction rise to ~40°C at 150mA in ambient 40°C, enabling passive thermal management. |
Pinout & Package
The AP7350D-12CF4-7 uses the X2-WLB0606-4 wafer-level chip-scale package (0.64mm × 0.64mm, 0.35mm height), featuring SnAgCu solder balls 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 to GND. |
| 2 (GND) | Ground reference | Primary return path for input, output, and internal circuitry; must be connected to low-impedance system ground plane. |
| 3 (VOUT) | Regulated output | Delivers stable 1.2V to load; connects directly to decoupling capacitor and load; internally discharged when EN = low. |
| 4 (VIN) | Input power supply | Accepts 2.0–5.25V DC; requires local 0.1µF ceramic capacitor placed adjacent to pin to suppress supply noise and transients. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 0.25µA typical enables >1-year battery life in coin-cell-powered IoT nodes with 10µA average system current. |
| Integrated active output discharge | 35Ω discharge path eliminates need for external pull-down resistor, reducing BOM count and PCB area in portable designs. |
| Miniature WLCSP footprint | 0.64mm × 0.64mm X2-WLB0606-4 saves >70% board space vs. SOT-23-5, critical for compact wearables and camera modules. |
| High accuracy over temperature | ±2% VOUT tolerance from -40°C to +85°C ensures reliable MCU core voltage even in outdoor or industrial environments. |
| Robust process reliability | Qualified to JESD 22 (4kV HBM ESD), JESD 78 (400mA latch-up), and RoHS 3/Halogen-free standards for long-life consumer and industrial use. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1202E/TT (Microchip) | Same 1.2V/150mA rating but no active discharge; 1.6µA IQ; SOT-23-5 package (1.3mm × 2.8mm). | Lacks discharge function; requires external pull-down for VOUT decay; larger footprint increases layout complexity in space-limited designs. | Select when discharge is unnecessary and cost sensitivity outweighs size/power advantages. |
| Torex XC6210B122MR-G (Torex) | 1.2V/150mA with 0.6µA IQ and 0.35V dropout; no discharge; USP-4 package (1.2mm × 1.6mm), larger than X2-WLB0606-4. | Higher IQ increases battery leakage; no discharge path; larger package consumes ~3× more board area than AP7350D. | Consider only if supply chain constraints preclude Diodes parts and discharge is not required. |
Compared with MCP1700T-1202E/TT and XC6210B122MR-G, the AP7350D-12CF4-7 uniquely combines sub-µA quiescent current, integrated discharge, and industry-smallest WLCSP footprint-delivering measurable BOM reduction, PCB area savings, and extended battery runtime in miniaturized portable systems.

FAQ
What is the purpose of the active output discharge feature in AP7350D-12CF4-7?
The active output discharge feature rapidly pulls VOUT to GND via an internal 35Ω switch when the EN pin is driven low. This prevents floating output voltage during shutdown, avoids unintended power-on of downstream circuitry, and eliminates the need for external discharge resistors-reducing BOM count and PCB area in space-constrained designs like wearables and medical patches.
Can AP7350D-12CF4-7 operate from a single alkaline AA battery?
Yes. With a minimum input voltage of 2.0V and 0.60V dropout at 150mA, the AP7350D-12CF4-7 can regulate 1.2V output down to ~1.6V input. A fresh AA alkaline cell provides ~1.6V at end-of-life, enabling full operational range across the battery's discharge curve-ideal for long-life remote sensors and handheld devices.
How does the X2-WLB0606-4 package affect thermal performance?
The X2-WLB0606-4 package has a θJA of 267°C/W on a JEDEC-standard PCB. At 150mA load and 40°C ambient, junction temperature rises ~40°C-well below the 125°C maximum. Its wafer-level construction provides low thermal resistance from die to board, but requires careful layout: short, wide traces to VIN/VOUT/GND and a solid ground plane beneath the device to maximize heat dissipation.
Is AP7350D-12CF4-7 suitable for automotive applications?
No. The AP7350D-12CF4-7 is qualified for industrial temperature range (-40°C to +85°C) but is not AEC-Q100 qualified. Diodes Incorporated explicitly states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing-none of which apply to this part. Use only in consumer, medical, or industrial non-automotive systems.
