TPS7A0508PDBZR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

TPS7A0508PDBZR from Texas Instruments, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin that must be connected to ground on the board.
2 OUT output Regulated output pin that requires a capacitor from OUT to ground for stability, at the recommended value or larger from the Recommended Operating Conditions table.
3 IN input Input pin that needs the recommended value or larger ceramic capacitor from IN to ground, as listed in the Recommended Operating Conditions table.
