RS8052XK

Jiangsu RUNIC Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOP-8

RS8052XK from Jiangsu RUNIC Tech, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Op-amp channel A output. Rail-to-rail output driver, short-circuit current typically ±30 mA; output should be current-limited to ≤55 mA.
2 -INA input Inverting input, channel A. Rail-to-rail CMOS input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs = 5.5 V); clamp current must stay ≤10 mA.
3 +INA input Noninverting input, channel A. Rail-to-rail CMOS input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs = 5.5 V); clamp current must stay ≤10 mA.
4 V- power_in Negative (lowest) power supply. Together with V+ sets the supply span Vs = (V+) − (V−), rated 1.4 V to 5.5 V (absolute max 7 V). Typically ground in single-supply operation.
5 +INB input Noninverting input, channel B. Rail-to-rail CMOS input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs = 5.5 V); clamp current must stay ≤10 mA.
6 -INB input Inverting input, channel B. Rail-to-rail CMOS input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs = 5.5 V); clamp current must stay ≤10 mA.
7 OUTB output Op-amp channel B output. Rail-to-rail output driver, short-circuit current typically ±30 mA; output should be current-limited to ≤55 mA.
8 V+ power_in Positive (highest) power supply. Together with V− sets the supply span Vs = (V+) − (V−), rated 1.4 V to 5.5 V (absolute max 7 V). Bypass with 100 nF to V−.
