Product details

Overview

AP7350-15CF4-7 from Diodes Incorporated is a 150mA ultra-low quiescent current (0.25µA typ) fixed-output 1.5V LDO regulator in X2-WLB0606-4 wafer-level chip-scale package, featuring ±1% output voltage accuracy, 2.0V–5.25V input range, and enable-controlled shutdown for battery-powered wearable electronics and IoT sensor modules.

For engineers reviewing the AP7350-15CF4-7 datasheet, AP7350-15CF4-7 pinout, AP7350-15CF4-7 application, or AP7350-15CF4-7 equivalent, key selection criteria include ultra-low standby current (0.02µA), dropout voltage of 0.43V at 150mA (for 1.5V output), EN logic thresholds (0.4V low / 1.0V high), and thermal resistance (267°C/W) in its 0.64mm × 0.64mm footprint.

Technical Context

The AP7350-15CF4-7 integrates a precision voltage reference, error amplifier, current-limit circuit, and active-high enable input to deliver stable 1.5V output with minimal external components. Its architecture supports fast load transient response (e.g., 1→50mA step at V_IN=3.3V/V_OUT=1.2V) and maintains regulation down to 2.0V input.

Designed for minimal board space, it operates across –40°C to +85°C ambient, uses SnAgCu solderable balls, and meets JESD 22 ESD ratings (4kV HBM, 400V MM) and JESD 78 latch-up (>400mA). No internal discharge path - distinct from AP7350D variants.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.5V ±1% at +25°C; ±2% over full temperature range - ensures tight rail tolerance for low-voltage microcontrollers and sensors.
Quiescent Current	0.25µA typical - enables multi-year battery life in always-on wearables and remote IoT nodes.
Dropout Voltage	0.43V max at 150mA - allows operation from single-cell Li-ion (3.0V min) or two alkaline cells (2.4V min) while sustaining full load.
Input Voltage Range	2.0V to 5.25V - compatible with common battery chemistries and intermediate supply rails.
Enable Thresholds	V_EN(H) ≥ 1.0V, V_EN(L) ≤ 0.4V - interfaces directly with 1.8V/3.3V GPIO without level-shifting.
Thermal Resistance θ_JA	267°C/W - requires minimal PCB copper area for thermal management in space-constrained layouts.
ESD Protection	4kV HBM, 400V MM - robust handling during assembly and end-use in portable environments.

Pinout & Package

AP7350-15CF4-7 is housed in the X2-WLB0606-4 wafer-level chip-scale package (0.64mm × 0.64mm × 0.34mm), with SnAgCu solderable bumps and moisture sensitivity level 1 (J-STD-020).

Pin/Terminal	Circuit Role	Design Meaning
1 (EN)	Enable control input	Active-high logic input; must be driven (not floating); ties to VIN for permanent ON; controls 0.02µA standby mode.
2 (GND)	Ground reference	Primary return path for input/output current; requires low-impedance connection to PCB ground plane for stability.
3 (VOUT)	Regulated output	Delivers 1.5V ±1% to load; requires 0.1µF ceramic capacitor placed adjacent to pin for transient response and stability.
4 (VIN)	Power input	Accepts 2.0–5.25V; requires 0.1µF decoupling capacitor near pin to suppress supply noise and support load steps.

Key Features

Feature	Design Value
Ultra-low quiescent current	0.25µA typical enables >10-year battery life in coin-cell-powered devices at µA-level average load.
Miniature WLCSP footprint	0.64mm × 0.64mm area reduces PCB real estate by >50% vs. SOT-23, critical for compact wearables and camera modules.
High output accuracy	±1% at +25°C ensures reliable operation of 1.5V I/O domains in MCUs and image sensors without external trimming.
Integrated enable function	EN pin provides clean on/off control with <0.4V low threshold, eliminating need for external MOSFET or logic gate.
Robust process reliability	Qualified to JESD 78 (>400mA latch-up) and JESD 22 (4kV HBM), supporting high-yield manufacturing and field durability.

Applications

Use Scenario: Continuous heart-rate monitoring using optical sensor and BLE SoC powered by CR2032 coin cell.

IC Role / Device Role / Timing Role: Primary 1.5V power rail for analog front-end and digital logic; regulated supply enabling consistent ADC sampling and RF transmission.

Use Value: 0.25µA quiescent current extends battery life to 3+ years; 0.64mm² footprint fits within tight wristband PCB constraints.

Use Scenario: Battery-powered temperature/humidity sensor transmitting data hourly via LoRaWAN.

IC Role / Device Role / Timing Role: Stable 1.5V bias for precision analog sensor interface and microcontroller core voltage during brief transmit bursts.

Use Value: ±1% output accuracy prevents sensor calibration drift; 0.43V dropout allows operation until battery reaches 1.93V, maximizing usable capacity.

Smart Camera Module

Medical Patch Monitor

Use Scenario: Miniaturized USB-C camera dongle with CMOS image sensor and ISP ASIC.

IC Role / Device Role / Timing Role: Dedicated 1.5V LDO for image sensor analog supply, isolated from noisy digital rails.

Use Value: Low ESR capacitor compatibility and fast transient response (<10µs recovery) prevent image artifacts during exposure changes.

Use Scenario: Disposable ECG patch operating for 7 days on a single button cell.

IC Role / Device Role / Timing Role: Main power regulator for ultra-low-power MCU, analog front-end, and Bluetooth LE radio.

Use Value: 0.02µA standby current minimizes leakage during sleep cycles; JESD 22 ESD rating protects against handling damage during clinical deployment.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700T-1502E/TT	Higher quiescent current (1.6µA typ), SOT-23-5 package (1.6mm × 2.9mm), no enable pin.	Lacks enable control; larger footprint limits use in ultra-compact designs; higher IQ reduces battery life in always-on modes.	Select when enable functionality is unnecessary and board space permits larger package.
Torex XC6210B152MR-G	0.25µA IQ, same 1.5V output, but SOT-25 package (2.9mm × 2.8mm); includes CE pin with 0.7V threshold.	CE threshold incompatible with 1.8V GPIO without pull-up; 10× larger footprint increases layout complexity in wearables.	Choose only if existing design uses SOT-25 and CE logic levels align with host controller.

Compared with MCP1700T-1502E/TT and XC6210B152MR-G, AP7350-15CF4-7 uniquely combines sub-µA IQ, enable control with 1.0V logic-high threshold, and industry-smallest 0.64mm² footprint - making it optimal for next-gen miniaturized battery systems where every micron and nanoamp matters.

FAQ

What is the maximum output current and corresponding dropout voltage for AP7350-15CF4-7?

The AP7350-15CF4-7 delivers up to 150mA output current. At this load and 1.5V output, its dropout voltage is specified as 0.43V maximum (typical 0.32V), meaning it maintains regulation as long as VIN remains ≥1.93V. This value is confirmed in the Electrical Characteristics table under "Dropout Voltage" with test condition IOUT = 150mA, VOUT = 1.5V.

Does AP7350-15CF4-7 include an internal output discharge transistor?

No, AP7350-15CF4-7 does not include an internal output discharge path. It is the non-discharge variant (as indicated by absence of "D" in the part number suffix). The discharge-capable version is AP7350D-15CF4-7, which adds a ~35Ω active pull-down between VOUT and GND when EN is low.

What capacitor values and types are recommended for stable operation?

Diodes specifies 0.1µF X5R or X7R ceramic capacitors for both CIN (between VIN and GND) and COUT (between VOUT and GND), placed as close as possible to their respective pins. These dielectrics ensure stable ESR over temperature and prevent oscillation. Bulk low-ESR capacitors may be added for large load transients, but the LDO is stable with just the 0.1µF ceramics.

Can AP7350-15CF4-7 be used in automotive applications?

AP7350-15CF4-7 is not AEC-Q100 qualified and is not intended for automotive applications. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing - customers needing automotive qualification must contact Diodes directly for designated parts, as this variant is designed for commercial/industrial portable electronics only.
