AP7365-SNG-7 Visão geral
A low-dropout (LDO) regulator is a type of linear voltage regulator that maintains a stable output even when the input voltage approaches the output voltage. LDOs sit within the broader family of linear regulators, which are themselves a subset of voltage regulators and the parent power-management IC (PMIC) category. Unlike switching regulators, LDOs do not introduce switching noise, making them preferred for noise-critical rails in mixed-signal systems.
Key features of the AP7365-SNG-7 include its 600 mA continuous output capability, low 35 µA quiescent current that preserves battery life, 65 dB PSRR at 1 kHz for ripple rejection from upstream converters, and a fixed soft-start characteristic that prevents input current surges during turn-on. The exposed thermal pad (EP) on the bottom of the U-DFN2020-6 package enhances heat dissipation and enables higher sustained current without a heatsink.
The AP7365-SNG-7 uses a P-channel MOSFET pass element, which is the architectural choice that allows the very low 35 µA quiescent current (PNP-based LDOs typically draw 1-10 mA). The trade-off is slightly higher dropout voltage versus an N-channel architecture with a charge pump, but in most 3.3 V or 5 V rail applications this dropout is comfortably met.
Typical applications include single-cell lithium-ion battery-powered portable electronics, USB peripherals, wireless sensor nodes, IoT edge devices, and post-regulation stages following DC-DC converters where a clean, low-noise rail is required.
When designing with this device, place 1 µF ceramic input and output capacitors as close to the IC as possible, choose X5R or X7R dielectric for stable temperature performance, and use the exposed pad to drop thermal resistance to approximately 60°C/W on a 1 oz copper pour.

Aplicações típicas
AP7365-SNG-7 é adequado para 6 aplicaçãos: Single-Cell Li-Ion Battery-Powered Portable Devices, USB-Powered Peripherals and Dongles, IoT Edge Sensor Nodes, Post-Regulation After DC-DC Converter, Wireless Sensor and BLE Modules, Industrial Sensor and Process Control Boards.
Single-Cell Li-Ion Battery-Powered Portable Devices
The AP7365-SNG-7 is purpose-built for single-cell Li-ion battery-powered portable devices where its 2 V to 6 V input range covers the full discharge curve from 4.2 V fully charged down to 3.0 V cutoff, while the 600 mV dropout at full 600 mA load maintains regulation even at low battery. Its 35 µA quiescent current adds only ~0.13 mW of drain on a 3.7 V cell, preserving standby time. With 65 dB PSRR at 1 kHz, it cleans up ripple from upstream DC-DC converters that often feed sensitive analog/RF rails. Designers place a 1 µF X5R ceramic on VIN and VOUT adjacent to the pins, and tie the exposed pad to a 1 oz copper pour to keep θJA near 60°C/W. This makes the AP7365 SNG-7 a strong fit for handheld instruments, wearables, and other Li-ion powered products.
Recomendado
USB-Powered Peripherals and Dongles
The AP7365-SNG-7 fits USB-powered peripherals because its 6 V absolute maximum input tolerates the 5.0 V VBUS rail with margin, and its 600 mA continuous output comfortably supports downstream MCU, wireless, and LED loads. The 35 µA quiescent current ensures suspend-mode power budgets stay within USB spec. With 65 dB PSRR at 1 kHz, ripple from VBUS hot-plug events is rejected before reaching sensitive analog blocks. The U-DFN2020-6 footprint is small enough for USB-stick form factors. Compared to a switching regulator, the LDO adds no EMI that might upset RF chipsets or USB signal pairs. Designers add a 1 µF input cap to handle VBUS inrush and route the EP pad to a copper pour for the bottom layer.
Recomendado
IoT Edge Sensor Nodes
The AP7365-SNG-7 suits IoT edge sensor nodes because its 35 µA quiescent current allows months of standby on small lithium cells, while 600 mA peak output handles burst transmit loads from sub-GHz or BLE radios. The 65 dB PSRR at 1 kHz rejects switching noise from boost converters that often precede the LDO at low battery. The U-DFN2020-6 package is small enough for coin-cell sensor packages. The exposed pad allows continuous operation at high current without heatsinking in a sealed node enclosure. Designers add a 1 µF X7R output cap and use the ADJ pin with a precision divider to set the exact radio rail voltage. This makes the AP7365 SNG-7 ideal for thermostats, leak detectors, and asset trackers.
Recomendado
Post-Regulation After DC-DC Converter
The AP7365-SNG-7 is widely deployed downstream of a switching DC-DC converter where the designer needs a clean, low-noise rail for analog, audio, or RF circuitry. Its 65 dB PSRR at 1 kHz attenuates the switching ripple of a typical buck converter by a factor of ~1800×, and the LDO adds no additional switching noise of its own. The 600 mA output handles op-amps, codecs, and transceiver rails. The exposed thermal pad dissipates the (VIN - VOUT) × IOUT loss as heat across the copper pour. Designers place the LDO close to the noise-sensitive load, use a 1 µF X5R ceramic output cap, and route the EP pad to a 1 square inch copper area to manage dissipation at large VIN-VO deltas. This configuration is common in industrial control and audio boards.
Recomendado
Wireless Sensor and BLE Modules
The AP7365-SNG-7 fits wireless sensor and BLE module power trees because of its 35 µA quiescent current and 600 mA peak output — perfect for the duty-cycled transmit bursts of BLE radios that draw 30-80 mA peaks. With 65 dB PSRR at 1 kHz, it cleans up ripple on the VDD pin and improves RF spectral purity by reducing power supply noise coupling into the radio's VCO. The U-DFN2020-6 footprint is small enough for modules like sensor beacons. The exposed pad ties the EP pad to a copper pour for 1 oz copper. Designers add input/output 1 µF X7R ceramic capacitors, place them within 2 mm of the pins, and use the ADJ pin to set the precise radio rail voltage. This makes AP7365 SNG-7 a strong fit for BLE beacons and wearable sensors.
Recomendado
Industrial Sensor and Process Control Boards
The AP7365-SNG-7 is well-suited to industrial sensor and process-control boards where its -40°C to +85°C operating range handles factory floor environments, and the 65 dB PSRR at 1 kHz cleans up the noisy 24 V bus after a pre-regulator. The 600 mA output supports analog front-end, ADC, and isolated I/O subsystems. The exposed thermal pad on U-DFN2020-6 enables continuous operation at full load on a 1 oz copper pour without a heatsink. Built-in over-current, short-circuit, and thermal shutdown protection increase system robustness in fault conditions. Designers add reverse-polarity protection at the input, place a 1 µF X7R ceramic at VIN and VOUT, and tie the EP pad to the ground pour. This makes the AP7365 SNG-7 ideal for PLC analog front-ends, sensor transmitters, and process-condition alarms.

Notas de projeto
The AP7365-SNG-7's input capacitor (1 µF X5R/X7R ceramic minimum, placed within 2 mm of VIN) absorbs input-voltage transients during load steps and provides the instantaneous current that the P-channel pass element cannot source from the battery instantly. Output capacitor (1 µF X5R/X7R ceramic, also within 2 mm of VOUT) ensures loop stability — DO NOT use Y5V or low-CDV ceramics that derate severely with temperature, as the loop may oscillate at cold. For higher output current transients (>300 mA steps), increase COUT to 2.2 µF.
Estimated: at VIN=3.7 V, VOUT=3.3 V, IOUT=600 mA, the AP7365-SNG-7 dissipates approximately 0.24 W. With θJA near 60°C/W on a 1 oz copper pour with the exposed pad soldered, junction temperature rises ~14°C above ambient — well within the 150°C TJ limit. At VIN=5.0 V, VOUT=3.3 V, IOUT=600 mA, dissipation is approximately 1.02 W and junction rises ~61°C above ambient, so a larger copper pour (2+ sq inches) is recommended. Always tie the exposed pad to a contiguous ground plane.
Do not exceed the absolute maximum VIN of 6 V — a 6.5 V spike (above 100%) will permanently damage the device. Do not operate without the exposed pad soldered to PCB copper; thermal resistance rises sharply and the device may thermal-shutdown prematurely. Do not place a reverse-biased diode or large series inductance on the input — the AP7365-SNG-7 lacks reverse-current blocking and may discharge the output cap through VIN. Always check that VOUT does not back-drive VIN during power sequencing.
