When dropping a 5V source (like USB power or a drone's 5V BEC) down to 3.3V to power microcontrollers and RF chips, traditional LDO regulators waste a lot of energy as heat. This advanced switching regulator solves that problem by delivering up to 1A of continuous current with incredibly high efficiency, making it the go-to power IC for custom ExpressLRS receivers, flight controllers, and portable IoT devices.\u003c\/p\u003e\n\u003cp\u003ePerfectly suited for 1S LiPo\/Li-ion applications, it operates flawlessly from 2.3V to 5.5V. What makes the AP61100 truly shine is its ultra-high 2.2MHz switching frequency. This allows you to use a physically microscopic inductor and tiny ceramic capacitors, keeping your overall power circuit footprint incredibly small. Housed in a tiny 6-pin SOT-563 package and drawing a mere 15µA of quiescent current, it is the ultimate highly-efficient power solution for space-constrained, battery-operated DIY electronics.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eLDO Replacement:\u003c\/b\u003e Offers significantly higher efficiency and drastically less heat generation compared to standard linear regulators when stepping down 5V to 3.3V or 1.8V.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003e1S LiPo Ready:\u003c\/b\u003e The 2.3V to 5.5V input range makes it perfect for directly powering 3.3V logic from a single-cell (1S) LiPo battery commonly used in TinyWhoop drones.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSpace-Saving Design:\u003c\/b\u003e The 2.2MHz switching frequency allows for the use of ultra-small external components, saving crucial PCB real estate.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eUltra-Low Quiescent Current:\u003c\/b\u003e Draws only 15µA in standby, maximizing battery life for portable and always-on electronics.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePart Number:\u003c\/b\u003e AP61100Z6-7\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eIC Type:\u003c\/b\u003e Synchronous Step-Down (Buck) DC-DC Converter\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eInput Voltage Range:\u003c\/b\u003e 2.3V to 5.5V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eOutput Voltage:\u003c\/b\u003e Adjustable (0.6V to 3.6V)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMax Output Current:\u003c\/b\u003e 1A\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePackage Type:\u003c\/b\u003e SOT-563 (1.6 x 1.6 mm, SMD\/SMT)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RC-LIFE","offers":[{"title":"Default Title","offer_id":54285719994706,"sku":null,"price":10.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1065\/8067\/2850\/files\/31_SOT563_6_sml.webp?v=1786960691","url":"https:\/\/rc-life.com\/pl\/products\/ap61100z6-7-1a-synchronous-step-down-converter-2-3-5-5v-sot-563","provider":"rc-life","version":"1.0","type":"link"}
