Yl105 Datasheet Better Jun 2026

The "105" series is a common designation for single-cell lithium-ion battery protection ICs. These are used to prevent overcharging, over-discharging, and over-current.

The datasheet mentions "VDD ripple < 50mV." In reality, if you power the YL105 from the same 5V rail as a servo motor, you will get +10% RH errors. Use a dedicated 3.3V LDO regulator or add a 470µF capacitor on the power rail.

| Feature | YL-105 | FC-37 / YL-83 | |--------|--------|---------------| | Analog output | Yes | Yes | | Digital output | Yes | Yes | | On-board comparator | LM393 | LM393 | | Potentiometer | Yes (screw-type) | Yes | | LED indicators | Power + Trigger | Power + Trigger |

The YL‑105 model is also widely used for a . This is a complete security system: a main unit with an infrared sensor and a 105 dB siren, plus two remote controls. Several brands (Yilin, Verk, APT, Platinium) sell this product under the same YL‑105 model number. The "105" series is a common designation for

A standard Arduino Uno onboard 3.3V regulator is meant for low-power sensors and often drops below stable margins during RF transmission bursts. This power sag causes the radio to reset mid-packet, showing up as persistent 0x00 or 0xFF SPI register read errors in debugging consoles. The YL-105 completely offloads this burden by drawing from the much stronger 5V power rail and stepping it down locally. 2. Lack of High-Frequency Decoupling Another NRF24 problem - works on one Uno but not others

: Eliminates the need for external voltage dividers or dedicated 3.3V power supplies that may not provide enough current on certain Arduino clones. Use a dedicated 3

High Power Supply Rejection Ratio (PSRR) to filter out digital switching noise. Peak currents up to 800mA (LDO rated)
