AP7350-30CF4-7 Présentation
An LDO (low-dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input-to-output voltage differential is very small. LDOs belong to the broader hierarchy of linear regulators, which in turn are a subset of voltage regulators and ultimately power management ICs (PMICs). Unlike switching converters, LDOs dissipate excess energy as heat, making them ideal where low noise, small footprint, and minimal external part count outweigh efficiency concerns.
Key differentiating specifications of the AP7350-30CF4-7 include: 0.25 µA typical quiescent current (extend battery life in always-on rails), high output voltage accuracy of ±1% across line/load/temperature, integrated active-high enable for sleep-mode gating, and built-in short-circuit and thermal protection. The CMOS process enables a tiny quiescent current that is orders of magnitude lower than bipolar LDOs in the same load class.
Architecturally, the AP7350 uses a CMOS pass element paired with a precision bandgap reference and feedback loop, delivering clean, low-ripple regulation without the high-frequency noise that switching regulators generate. The X2-WLB0606-4 wafer-level package (0.6 mm × 0.6 mm × 0.4 mm height) is one of the smallest LDO footprints in the industry, allowing the regulator to fit beside an IC pad rather than under it.
Typical applications for the AP7350-30CF4-7 include wearable fitness bands, BLE beacons, IoT sensor nodes, hearing aids, and battery-powered data loggers. The 3.0 V fixed output is well-matched to Li-ion chemistries (3.0 V mid-discharge) and to low-power MCUs that operate from a 2.7–3.6 V supply such as the M0+ class.
When designing with this device, add a 1 µF X7R ceramic input/output capacitor and route the EN pin to the host MCU GPIO so that the regulator can be placed in 0.25 µA Iq shutdown between active windows. Keep input trace inductance low to preserve load-transient response.

Applications typiques
AP7350-30CF4-7 convient pour 6 applications: Wearable Fitness Bands, BLE Beacons and IoT Sensor Nodes, Hearing Aids and Medical Wearables, Battery-Powered Data Loggers, IoT Wireless Sensor Modules, Smart Home Sensor Hubs.
Wearable Fitness Bands
The AP7350-30CF4-7 fits wearable fitness bands because its 0.25 µA quiescent current extends coin-cell life by months while its 3.0 V fixed output matches the nominal discharge curve of CR2032 and similar lithium coin cells. The 150 mA continuous rating is more than sufficient to power the BLE SoC, accelerometer, and heart-rate sensor during active bursts. Housed in the 0.6 mm × 0.6 mm X2-WLB0606-4 package, the regulator occupies less than 0.4 mm² of PCB area - small enough to fit beside a QFN-packaged sensor on a 12 mm × 30 mm wristband module. The integrated enable pin lets the host MCU gate the LDO off between sensor samples for an additional 100× standby current reduction.
Recommandé
BLE Beacons and IoT Sensor Nodes
BLE beacons and IoT sensor nodes rely on the AP7350-30CF4-7 because 0.25 µA quiescent current is 50-100× lower than competing bipolar LDOs in the same footprint, letting the regulator stay enabled in always-on mode without draining a 240 mAh CR2477 battery for years. The 150 mA load rating covers peak BLE TX bursts (typically 30-50 mA) with ample margin, and the X2-WLB0606-4 0.6 mm × 0.6 mm package fits inside a 10 mm diameter beacon puck. The fixed 3.0 V output also feeds the 3.3 V-tolerant MCU with adequate headroom during transmit current spikes, while the integrated enable pin allows the SoC to fully power-down the LDO between transmissions to maximize battery life.
Recommandé
Hearing Aids and Medical Wearables
Hearing aids and medical wearables depend on the AP7350-30CF4-7 because its 0.25 µA quiescent current preserves the limited mAh budget of zinc-air or rechargeable Li-ion cells, and its tiny X2-WLB0606-4 0.6 mm × 0.6 mm footprint leaves room for the analog audio chain, DSP, and wireless receiver. The 150 mA continuous rating comfortably drives modern audio codecs such as the AK4621EF during peak playback, while the fixed 3.0 V output matches the most common analog rail for low-voltage audio amplifiers. The integrated enable pin lets the device enter sub-µA shutdown when the aid is in standby mode, and the CMOS architecture produces no switching noise that could couple into sensitive microphone preamplifiers.
Recommandé
Battery-Powered Data Loggers
Battery-powered data loggers choose the AP7350-30CF4-7 because its 0.25 µA quiescent current keeps the regulator enabled indefinitely between sensor read cycles, extending the deployment lifetime of remote environmental loggers from weeks to years on a single AA cell. The 150 mA continuous rating drives SPI flash memory, MEMS sensors, and a low-power MCU during active logging windows, and the 5.25 V maximum input handles a 3× AA battery pack (4.5 V) or a USB charger feed (5 V) without external protection. The X2-WLB0606-4 package fits inside a 16 mm × 24 mm coin-cell powered PCB, and the integrated enable pin allows the MCU to power-cycle the LDO during deep sleep for additional savings.
Recommandé
IoT Wireless Sensor Modules
IoT wireless sensor modules benefit from the AP7350-30CF4-7 because its 0.25 µA quiescent current and small X2-WLB0606-4 footprint make it ideal for sub-1 GHz, Zigbee, or LoRa modules that spend 99% of the time in sleep mode. The 150 mA continuous rating covers the 80-100 mA peaks of typical sub-GHz transmitters, and the fixed 3.0 V output aligns with the most common RF IC supply rail. The integrated enable pin lets the host MCU gate the LDO entirely off during deep sleep, while the CMOS architecture emits no switching noise that could desensitize the adjacent RF receiver chain - a key advantage over switching converters in the same footprint class.
Recommandé
Smart Home Sensor Hubs
Smart home sensor hubs rely on the AP7350-30CF4-7 to power always-on sensor subcircuits such as PIR motion detectors, temperature/humidity sensors, and BLE pair-mode radios from a 3.0 V rail that draws only 0.25 µA in standby. The 150 mA continuous rating comfortably supplies a Zigbee or Thread radio during TX, and the X2-WLB0606-4 0.6 mm × 0.6 mm footprint fits inside compact hub enclosures where board area is at a premium. The integrated enable pin allows the host MCU to power-down the LDO entirely when the hub enters sleep, and the CMOS process ensures no switching ripple couples into the antenna or radio front-end.

Notes de conception
Place the input and output 1 µF X7R ceramic capacitors within 1 mm of the corresponding VIN (A1) and VOUT (A2) balls to maintain stability and load-transient response. The X2-WLB0606-4 wafer-level package relies on bottom-side balls for thermal dissipation as well as electrical contact, so use a non-solder-mask-defined (NSMD) land pattern with via-in-pad or micro-via fan-out to keep the ground return loop short. Avoid routing noisy digital traces under the regulator.
The AP7350-30CF4-7 is a CMOS LDO, so power dissipation equals (VIN - VOUT) × IOUT. At maximum VIN 5.25 V, VOUT 3.0 V, and 150 mA full load, the regulator dissipates 338 mW - well within the X2-WLB0606-4 thermal limits thanks to the small die size and bottom-ball ground pad. At lower headrooms (e.g., VIN 3.3 V to VOUT 3.0 V), dropout falls below 300 mV at 150 mA and the device enters dropout region - ensure VIN is at least 0.3 V above VOUT at peak load.
Do not omit the EN pull-down resistor if the EN ball is left floating - per the Diodes AP7350 datasheet, an undefined EN pin may float into an indeterminate state that draws additional quiescent current or causes unstable regulation. Tie EN to VIN with a 100 kΩ resistor if always-on operation is required, or to a host MCU GPIO if shutdown is needed. Also note that the X2-WLB0606-4 package is moisture-sensitive; assembly lines should bake parts before reflow and observe the MSL rating (consult datasheet for the exact MSL level).
