# RK860-2 (Component) ## Description Buck Switching Regulator IC 0.5V~1.5V 1 Output 7A WLCSP-20 The RK860-2 is a low-dropout (LDO) linear voltage regulator IC designed to provide a stable, low-noise output voltage from a higher input supply. It is commonly used in small electronic modules, microcontroller power rails, and low-power analog/digital circuits where clean voltage regulation is important. Type: Low Dropout Linear Regulator (LDO) Input voltage: Typically up to ~6V (varies by variant) Output voltage: Fixed or adjustable (depends on suffix version) Dropout voltage: Low (suitable for battery-powered systems) Output current: ~300 mA to 600 mA class (package dependent) #CommonPartsLibrary #IntegratedCircuit #PowerManagement #RK860 ## Component Details - **Owner:** adrian95 - **Created:** 4/17/2026 - **Last Updated:** 4/17/2026 - **Visibility:** Public - **Datasheet URL:** https://www.lcsc.com/datasheet/C5156489.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=FlkNBAIDRQULVABfFAVZBgZVFVZYBgZSQ1NeBVIFQlExVlNRQVVeV11RR1NdVDsOAxUeFF5JWBYZEEoBGA4JCwFIFA4DSA%3D%3D - **License:** https://creativecommons.org/licenses/by/4.0/ - **Part Type:** Power Management - **LCSC Part Number:** C5156489 - **Manufacturer Part Number:** RK860-2 - **Manufacturer Name:** Rockchip - **Symbol Style:** parametric-v1 - **Part Type:** Integrated Circuits - **Sub-Type:** Logic - **MPN:** RK860-2 - **Package / Case Code:** WLCSP - **Pin Count:** 20 - **Logic Function:** Monitor ## Pins | Pin | Name | Type | |-----|------|------| | A1 | VSEL | | | A2 | EN | | | A3 | SCL | | | A4 | VOUT | | | B1 | SDA | | | B2 | GND | | | B3 | GND | | | B4 | AGND | | | C1 | GND | | | C2 | GND | | | C3 | GND | | | C4 | GND | | | D1 | VIN | | | D2 | VIN | | | D3 | LX | | | D4 | LX | | | E1 | VIN | | | E2 | VIN | | | E3 | LX | | | E4 | LX | | --- *Generated from [https://www.flux.ai/adrian95/rk860-2~91t](https://www.flux.ai/adrian95/rk860-2~91t)*
